INSIDE THIS ISSUE Taking a steel stand...but whose? . .6
Scholar gets a ‘reel’ education . . .36
U.S. Commerce Secretary Wilbur Ross is shepherding a Section 232 investigation into whether steel exports represent a national security threat to the U.S., a case that splits domestic producers. See p. 6. What’s likely to happen? By the time you read this, it could be old news. Speaking at a June 19 summit, Ross said that he expected a decision to be made shortly, and that President Trump would take swift action that could include tariffs or quotas. “The president being the president, I don’t think he will dilly dally very long on making his decision, whatever it turns out to be,” Ross was quoted as saying in an article in Reuters. “I would expect this to come to a head during the month of June.”

EDITORIAL EDITORIAL
U.S. investigation of exported steel: it’s a matter of timing, perspective & politics The steel sector has been used as a political football more than once, so when the U.S. Commerce Dept. on June 20 held the first Section 232 investigation on steel since 2001, it was a telling moment, one that largely splits the industry between those that produce their own steel and those that must buy it to process. Per Section 232 of the Trade Expansion Act of 1962, the Secretary of Commerce can investigate the effects of imports on national security and recommend actions that include tariffs and quotas. Since 1980, 14 such investigations have been held. By law, Commerce has 270 days to present its recommendations. Commerce Secretary Wilbur Ross has already indicated that the investigation would soon be concluded, while the rules allowed a decision to be made as late as January 2018. Richard Chriss, president of the American Institute for International Steel (AIIS)—which maintains that duties would harm steel consumers more than it would benefit producers—has called for more hearings. Opponents counter that would only allow more damage. Nucor Corporation President John Ferriola said that China was the key to the crisis, but other countries, like Korea, Brazil, Russia and Turkey, have also driven excess steel capacity. “These governments continue to flood the world with artificially cheap steel, and much of it finds its way to the U.S., where markets are open and the government doesn’t keep mills in business for political reasons.” Some three dozen speakers spoke on the merits of the matter. A 2017 Commerce Department’s Steel Industry Executive Summary found that overall U.S. capacity use was 71% in 2016, a drop from 77.5% in 2014. March 2017 steel imports to the U.S. are 34% higher than those in March 2016, a dramatic increase. The above is a “big steel” issue, but the same dilemma—what happens if a “remedy” results in even more damage—is also at the heart of a separate matter on steel wire rod exported by 10 countries. In addition to the above 232 investigation, which stems from a campaign pledge by President Donald Trump, there is a parallel Section 232 action that covers aluminum. Each side has a long list of supporting facts, but at the end of the day, it seems that the issue is only crystal clear to those who have a decided interest in the outcome.

sub-Saharian Africa. The cable system will stretch from Mauritius to Rodrigues, to the east coast of South Africa and then on to the east coast of India. Per the release, the design calls for ultimate capacity of more than 13 Tbits-per second per fiber pair. ASN will also be in charge of project management, system design, marine operations and system commissioning, supported by IOX personnel. The project will result in “easy connectivity to current and future undersea cables on the east and west coast of Africa, delivering a gateway to the continent and a new alternate route between Asia and Africa.”

LS Cable & System Asia, a holding company for South Korea’s LS Cable & System, has won a US$10 million deal to supply ultra-high voltage cables (UHV) to DONG Energy, a state-run energy company in Denmark. A press release said that the contract calls for providing 1.5 km-long cables that are approximately three times the length of traditional high-voltage cables. The advantage of the long-distance cables, preferred in Europe, is that they cut down on construction costs such as connection material and installation cost and periods.

Foreign direct investment (FDI) registered from January to April increased to $10.95 billion, up 40.5% year-on-year, according to the Vietnamese government. Southern Vietnam, in which LSCV is located, has ongoing projects, including building a power plant and foreign firms’ factories, increasing demand for cables.
Wire & cable in the news British Steel: a success story for the ages What a difference a year can make. In a stunning reversal of fortunes, the ailing U.K. longsteel business of Tata Steel—which posted a record £79 million annual loss at the end of March 31, 2016—has seen stunning success. On June 1, 2016, the entity was sold for £1 to Greybull Capital LLC, and the results for the new business with an old name—British Steel—have been the stuff of a Horatio Alger novel. To younger readers, let’s just say that Horatio Alger means a wishes-come-true turnaround that seems to defy the harshness of the real world. And that seems to define what has happened at British Steel. Jobs have been restored, pay cuts ended, staffers given a stake in the company and more capital investment committed for future growth. The good news knows no bounds, as even the new employee publication just won an award. “In 12 months we have started transforming from an inward-looking production hub into a profitable, more agile business by controlling costs, improving our product range and quality, and through strategic investments,” said British Steel Executive Chairman Roland Junck. “The transformation in this business is (due to) our remarkable people who have embraced, engineered and led change. ... (They) are the reason I have great optimism for the future of British Steel.” Below are some of the highlights: • Operating as an independent business, British Steel reported a £47 million profit (EBITDA), its best performance in a decade for its five independent business units. The business’s financial turnaround started shortly before British Steel was launched by Greybull Capital, which made £400 million available. • One of those five sectors, wire rod activities, achieved the highest sales and manufacturing output in six years, with continuing success in automotive sales growth. The product range has been expanded, with significant sales success into the bright drawing markets.
The British Steel flag is flying briskly. • Staff pay cuts of 3% that were a key to the sale and turnaround plan have ended, and since June 1, 2016, 500 new employees have joined the company. • Employees are being given 5% of the business. “As we look to further grow the business it is important our employees, who have played such a vital role... should share in our future success,” Junck said. • The company has been awarded International Standard ISO 9001:2015, Quality Management Systems by Lloyd’s Register Quality Assurance (LRQA), among the first 6% of LRQA’s U.K. clients to transition to the 2015 standard. • The turnaround has enabled the company to announce plans to invest a further £40 million in capital investment 2017-18. • In June, the new monthly employee newspaper, Steel Matters, won the Chartered Institute of Public Relations’s Excellence Award for Best Internal Publication. In March, the company won six awards at Transform Awards Europe, including the Grand Prix award for overall excellence in rebranding. • And, in a timely coincidence, Bruce Jones, a technical account manager for British Steel, was chosen to serve as the 2017 Wire Link Scholar, a unique U.K./ U.S. industry program. A report on his two-weeks spent in the U.S., touring different plants as well as attending Interwire 2017, starts on p. 36 in this issue.

JDR has been named a preferred cable supplier for floating wind farm project U.K.-based JDR, a supplier of subsea power cables and umbilicals to the global offshore energy industry, reports that it has been selected by WindPlus as the preferred cable supplier for the Windfloat Atlantic (WFA) 25 MW floating wind farm.
JDR is a preferred supplier for the WFA wind farm. A press release said that the project, located off the coast of Viana de Castelo in Northern Portugal, will see the industry’s first application of dynamic cables operating at 66 kV. The scope of supply includes the design and manufacture of array cables to suit V164 floating turbines. The floating wind turbines will be connected via a network of inter-array cables to one export cable. A company representative informed WJI that JDR is the lone preferred cable supplier. Also, that the amount of cable was not cited as that will depend on final layout of the wind farm. The release said that JDR will deploy its dynamic cable break-away system that protects the floating platform as well as HV termination and testing. James Young, Chief Technology Officer at JDR, said that a key to landing the contract was the company’s experience “in designing and optimizing the cable configuration and accessories to meet the needs of this floating offshore wind project.” The release said that WFA brings together two pioneering developments in array cables: dynamic cable design for floating offshore wind and high-voltage power trans-

Craig Wire acquires Von Roll Austral Craig Wire Products (CWP) announced that it has acquired Von Roll Austral, Inc. (VRA), a manufacturer of shaped and heavy round copper magnet wire. The two U.S. companies are both based in Georgia: CWP in Temple and VRA in Douglasville, with a combined 40 years of experience of providing shaped and heavy round magnet wire for quick delivery and short run requirements. The acquisition combines the strength and assets of the two companies and allows Craig Wire to enhance its “Quick Time” manufacturing capabilities. Per Craig Wire Products, which specializes in short runs (250 lb) of copper magnet wire, Von Roll wanted to exit magnet wire in the U.S. as it was not in their long-term
strategy. The production equipment at VRA, which owns its plant, was described as being in good condition. The plant has 42 staffers while CWP, which has 33 employees, is now managing the VRA operations. “Our focus and main priority at this time is to integrate the two (operations).” VRA is one of four U.S. businesses that is part of the Swiss-based Von Roll Group, which notes at its website that it will continue to operate in the wire business, particularly in France and India.

Taihan Electric Wire reports winning contracts, plans for JV in Saudi Arabia Earlier this year, South Korea’s Taihan Electric Wire Co., Ltd., (TEW), reported winning two power cable contracts in the Middle East, and also announced that it will create a joint venture in Saudi Arabia for HV cable accessories. Per two press releases, TEW reported that it has won an order worth US$43 million for a 380 kV Extra-High Voltage (EHV) cable project in Saudi Arabia. The order, from Saudi Electricity Company-EOA, calls for TEW to install a 118-km underground power line to link substations between Doha and Qurayyah. The large-scale project also calls for TEW to supply cable accessories, make connections and perform testing. The second order, worth US$19 million, is for a 300 kV EHV cable project in Kuwait to be installed at a new oil refinery in Al-Zour. The turnkey system project will also include connections, civil engineering and even testing. In related news, TEW announced that it will establish a production company for HV in Riyadh, the capital of Saudi Arabia, as part of its localization strategy. The JV, to be called SAUDI TAIHAN, is being jointly funded by the Mohammed Al-Ojami Group, a local cable accessory company in Saudi Arabia. TEW plans to build a basic production facility that covers about 8,000 sq m before year’s end.
The new JV will be the first HV-class cable accessory company located in Saudi Arabia, the release said. It noted that Saudi Arabia has previously had to import HV-class cable accessories from Germany and the U.S. The new venture will increase TEW’s “competitive edge by localizing production based on its technical prowess,” it said. It noted that TEW now has production plants and corporations, including cable and cable accessory factories in South Korea, TCV in Vietnam and M-TEC in South Africa. Per Wikipedia, TEC was established in 1955 as the first wire and cable company in South Korea.

World Bank to provide the funding for subsea cable system in Pacific The World Bank announced that it has approved $36 million in grants to help provide reliable fiber-optic broadband internet in Kiribati and the Federated States of Micronesia (FSM). A press release said that the grants—$20 million for Kiribati and $16.26 million for FSM—will finance the installation of a subsea cable system that will connect Tarawa, Kiribati, to Nauru and Kosrae state, FSM, to Pohnpei state, FSM, which is connected to global networks. The Asian Development Bank is preparing finance to support Nauru’s participation in the cable system.
The projects are part of the Pacific regional connectivity program that seeks to bring more reliable and affordable internet to the majority of countries in the Pacific Islands. Kiribati and Micronesia are two of the world’s most remote island nations, covering six million square km of the Pacific Ocean, making access to information, services and economic opportunities a massive challenge. The projects will help to provide broadband internet to approximately 80,000 people. In the FSM, the states of both Yap and Chuuk already part of the Pacific regional connectivity program through the Palau-FSM Connectivity phase. The underwater cable systems for the two states are scheduled to be installed late this year, and be operational in early 2018. When completed, all four states in Micronesia will have access to broadband internet. “Just a few short years ago, no one would have believed such a project was possible,” said Yosiwo George, vice president of the FSM national government. The $36.26 million grants are provided through the International Development Association (IDA), the World Bank’s fund for countries most in need.
New Zealand to support project for a submarine cable to serve 3 islands New Zealand will contribute US$15 million toward connecting the Cook Islands of Rarotonga and Aitutaki and the island nation of Niue by a submarine cable. Per a report in Cook Islands News, Cook Island Prime Minister Henry Puna said at a ceremony that the cable system would link the two islands to faster, low-cost internet, which he said was essential for economic and social development. “The project will extend the existing Honatua subsea cable in the Pacific to Samoa, Niue and the Cook Islands, hopefully bringing us faster, more affordable and reliable internet services.”

The Manatua cable will have three fiber pairs operating at 30 Tbits per second. The main cable trunk will run between Apia and French Polynesia with branching units to Niue, Rarotonga, Aitutaki and Borabora. A consortium made up of the participating countries will construct, manage and own the cable. The final signing process for the Manatua cable agreement between the government of the French Republic on behalf of French Polynesia and the governments of Niue, Samoa and the Cook Islands coincided with the PITA 21st AGM and Tradeshow. Attending the event was New Zealand Prime Minister Bill English, who said that the project will enable Cook Islander citizens of New Zealand to benefit from the continuing and rapid advances in global technology. “In fact I’m sure, Prime Minister, you’ll have better connectivity here than in parts of New Zealand.” The cost for the project is estimated to be around $34.4 million, and with New Zealand providing $15 million, the remainder of the costs for the Cook Islands will be from the ADB, the report said. The expectation was that the cable would be ready in 2019.

WCMA annual golf tourney dodges rain hazard, scores splendid tourney The beauty of golf is that as long as one can play, it is a very good day. That was the story for the Wire & Cable Manufacturers’ Alliance (WCMA), as its Ed Fenton (love the shirt!) with June 5 annual WCMA Board President Tom Rosen. spring general membership meeting and golf outing at the Wethersfield Country Club was fortuitously sandwiched between two rainy days. WCMA Executive Director Ed Fenton thanked the 140 players and the sponsors for their generosity at the networking/dinner program, which included 10 non-playing guests. Proceeds for the event, which included a raffle and silent auction, go to cancer research at UConn. WCMA raised close to $3,000, and will match the funds, he said. The winning low-gross team was Jim Stocking, John Netta, Bob Smith and Sue Welsh while the first low net team was Mark Normandin, Bob Auger, Jim Hobensack and Joe Barry. Major sponsors for the event included Carris Reels, W. Gillies Technologies, Chase Corp. and James Monroe Wire & Cable.

PERSPECTIVES How to fathom the price of copper The publisher of The Copper Journal, John Gross is president of J.E. Gross & Co., Inc., a management consulting firm established in 1987, has worked with global leaders in the metals industry for more than 35 years. A highly decorated Vietnam Veteran, he has served as a director of the American Copper Council and as a member of the Comex Advisory Committee. Below is a recent column, followed by some questions from WJI. He can be contacted at john.gross@jegross.com, www.jegross.com.
What’s wrong with this picture?
1.8% to 23.461 mmt, resulting in a net deficit of some 55,000 mt last year. John E. Gross Thus, for the seventh consecutive year, the global copper market experienced a net deficit position, while the annual average price notched its fifth consecutive decline after peaking at $4 in 2011. How do we reconcile this apparent anomaly? Well, we can’t very easily, and this incongruity demonstrates the deepening complexity in attempting to logically analyze
Take a look at the below chart, which illustrates the relationship between the global market balance for copper and the Spot Comex annual average price. Based on the latest report from our friends at the International Copper Study Group, global production of refined copper rose 534,000 million metric tons (mmt), or 2.3% during 2016 from the prior year, to 23.406 mmt. Consumption on the other hand climbed 426,000 mt, or

To state the obvious, the bigger the numbers become, the more difficult it is to decipher them. WJI: Who are the winners and losers when the market acts as it currently does? Gross: I hesitate to say there are specific winners or losers, but those organizations that are acutely focused on managing their price risk in a disciplined, and consistent manner will typically come out ahead.
Further, it is startling when we look at the numbers from a more macro point of view. As the statistics below illustrate, between 1990 and 2015, global consumption of refined copper rose 111%; U.S. consumption fell 17%, while China saw a 2,137% increase. Let’s not talk about the production side. John E. Gross. Editor/Publisher, The Copper Journal

the global fundamentals for copper, as well as many other markets. In fact, on the numbers, between 2010 and 2016, the global copper market racked up a cumulative deficit of 1.48 mmt. Where did the metal come from? Here again, it is hard to say, but perhaps part of the answer may lie in the transparency, or lack thereof in statistics from China, which has evolved to become the world’s largest producer and consumer of copper, among other industrial materials.

ASIAN FOCUS Former Chinese steel executive among many sent to prison for taking bribes May 31 was a day or reckoning in China for some high-ranking officials, both in industry and public service, referred to by one report as “the single biggest day of judgment for high-level officials since President Xi Jinping came to power nearly five years ago.”
Deng Qilin in the courtroom where he was sentenced. Photo Xinhua/Zuma Press. A former chairman of Wuhan Iron and Steel (Group) Corp., Deng Qilin, was among those sentenced by the Intermediate People’s Court of Foshan in southern China’s Guangdong Province for taking bribes. The sentencing was one series of such actions taken as part of an anti-graft campaign. Per articles in Xinhua and The Wall Street Journal, on May 31 the court sentenced a range of individuals, including former provincial vice governors, senior bureaucrats and ex-chiefs of major state enterprises. “The point of these heavy sentences now is perhaps a warning to all the political elite that the current leadership can take down and severely punish anyone who does not toe the line,” said Victor Shih, a professor of political economy at the University of California at San Diego. Qilin, whose former company’s scope includes wire rod and wire for tire cord, was sentenced to 15 years in prison for accepting money for business favors and promotions. China Telecom’s Chang Xiaobing received a six-year sentence for taking bribes. Wang Baoan, a former head of the statistics agency, was given a life sentence, also for bribery. Deng was also fined approximately US$728,500, and his “illicit gains” will be turned over to the state treasury. He was found to have accepted bribes worth about US$8.15 million for favors in business, project construction and promotions, while holding a series of posts in the steel company between 2000 and 2015.

The court said Deng was given relatively lenient treatment for cooperating with investigators, handing over the proceeds of his crime, and providing information about crimes committed by others. Song Lin, the ousted chairman of major state-owned enterprise China Resources Holdings Co., received a 14-year prison sentence for embezzlement and bribery. Three former officials received life sentences: Lu Ziyue, former mayor of Ningbo in Zhejiang Province, for taking bribes worth US$21.6 million between 1999 and 2016; Chen Xuefeng, former member of the standing committee of the Communist Party in Henan province, for taking bribes worth US$18.4 million between 2000 and 2015 and embezzling US$809,000 of public funds; and Liu Zhigeng, former vice governor of Guangdong Province, for taking money and gifts worth US$4.4 million; former Sichuan Province Vice Governor Li Chengyun received 10 years for taking US$$976,000 in bribes; and former Guangdong Province senior legislator Wang Yang received 16-1/2 years for taking US$9.3 million in bribes and vote buying. Xinhua reported that the above actions follow prior steps taken by the top disciplinary arm of the Communist Party of China (CPC), which has “named and shamed 88 officials in 71 corruption cases that directly undermined public interests.” The CPC Central Commission for Discipline Inspection (CCDI) said the cases involved extortion of state subsidies, embezzlement of poverty relief funds, misappropriation of compensation for land requisitions, abuses of power and receipt of kickbacks. Those named on the list were not as high profile, but the scope was quite wide. A total of 3,333 officials in 2,412 cases have been named since the CCDI established the monthly reporting system to disclose such violations in July 2015. Investigation found that extortion of state subsidies for agriculture was the most common misdemeanor, followed by misappropriation of compensation for land requisitions and embezzlement of allowances for house renovation, according to the CCDI.

FIBER WATCH The country of Uzbekistan has plans to produce its first-ever fiber optical cable The country of Uzbekistan plans to start producing fiber optical cables in Tashkent so the country can become more independent in meeting its bandwidth needs. Per a report in uzdaily.com, the plant will have annual production capacity of 50,000 km of cable. That production will be used by national operator Uztelecom, which plans to use 277,000 km of cable by 2021. The announcement, by Sherzod Shermatov, acting Minister of Development of Information Technologies and Communications of Uzbekistan, calls for the plant to be built in the Chilanzar district on the premises of the joint stock company “Rele I Avtomatika.” He said that the project will save Uzbekistan some US$150 million. Per the report, the country plans to expand its internet gateway to 200 Gbps, up substantially from the current figure of 65.7 Gbps. The project furthers the country’s stated goals. An on-line government report said that it fits into the Strategy for Actions for the Republic of Uzbekistan, which has set five priority directions for 2017-2021. In an address by the Minister of Foreign Affairs of the Republic of Uzbekistan, H.E. Abdulaziz Kamilov, at the Senior Officials Meeting of the Member-States of the OIC Preparatory, the goals were outlined. The ministry seeks
The flag of the country of Uzbekistan, which plans to start production of fiber optical cables. “to intensify efforts on creation of high-quality communication links with high capacity in the field, especially in remote and isolated areas of the country. To do this, the ministry will lay new fiber optic cables and replace the existing terrestrial channels, upgrading software and hardware systems and telephone stations.” Per the Rele I Avtomatika website, the Chilanzar location, has 3.91 hectares of area, including a production site of 2.26 hectares where metal and plastic products are manufactured. That includes about a hundred types of low-voltage devices as well as corresponding services that are provided at the factory. There is a necessary infrastructure for further ramping up of the industry.

NORMA Group buys majority interest in Chinese fastener manufacturer Earlier this year, Germany’s NORMA Group announced that it has acquired an 80% stake in a Chinese manufacturer of joining products. A press release said that the NORMA Group, based in Germany, agreed to buy Fengfan Fastener (Shaoxing) Co., Ltd. (Fengfan), which is based in Shaoxing City, China. Founded in 1988, Fengfan manufactures joining products made of stainless steel, nylon and specialty materials. “With (this) acquisition, we are expanding our product portfolio and our position in the Chinese market,” said NORMA Group CEO Werner Deggim. With some 190 employees, Fengfan supplies shipbuilding, heavy industries and transport vehicle markets. Its preliminary annual sales amounted to approximately 15 million euros in 2016. Fengfan has a production and sales site in Shaoxing City in the Zhejiang Province.
Fastener maker nears completion of expansion of larger U.K. plant Hague Fasteners, a privately owned U.K.-based company founded in 1971 that makes threaded and milled special fasteners, reports that it has made very good progress on its plans to expand in a new nearby location.
A press release said that the company, based in Willenhall, is expanding into a new facility near its current location that is nearly triple the size. That move is expected to double production for the business. One of the company’s special focuses is on small batch critical special fasteners.
Jon and Claire Hague stoutly believe in U.K. potential. Earlier this year, company owners Jon and Claire Hague said that despite the decision by British voters to exit the EU, they believed that niche manufacturers would continue to grow, and decided to make a major investment. The company reports that its Quality Management System meets ISO 9001:2015, which makes it “one of the few specialist manufacturers that have seamlessly upgraded to the latest QMS standard and are proud to lead the way in the bolt & nut manufacturing sector.”

Richard Medoff General Manager Ace Metal, Inc. A 2017 WAI Life Member
Q: What year did you join WAI and why did you do it? What were you doing at the time? A: I joined the WAI in 1980, the year before Ace Metal exhibited at the first Interwire show. I was assistant plant manager and sales manager. Q: Did you have any sense that you had found a life-long career? A: I started working for Ace Metal in 1975 after finishing my military obligations and college. As my father had started the business, he was grooming me to eventually run the company. Q: What did you do and how did your career proceed over the years? A: I started out as a punch press operator, then assistant plant manager and continued up the ladder over the years. Ace Metal has been the only company I have ever worked for, which must seem pretty unusual. Q: What has been the best part of being in the wire and cable industry? Ever come close to leaving? A: The industry is expansive and offers many challenges. The camaraderie has been enjoyable, interesting and informative. I have met and worked with so many people over the years and the resulting friendships have lasted equally long. Over the years there were a few times when I thought of changing my line of work, but I’ve always been drawn back by the various hats that I wear here at Ace Metal. It keeps me engaged. Q: Looking back, how has being a WAI member contributed to your career? A: First, I want to note that I feel honored to be part of the wire and cable industry. It’s been a part of my life for most of my life, and to me it makes sense to be a member of the Association that represents it, and not just because we exhibit at its shows. When I travel for business—and not just in this great country, but to other countries as well—I am part of the U.S. wire and cable industry, and that carries some recognition, and the WAI is a part of that legacy.

CHAPTER CORNER The Midwest Chapter Scholarships for 2017 have a brotherly touch For the first time in the history of the WAI Scholarship Program, there are two winners from the same family in the same year. This rare designation belongs to the Stepanovic brothers—Scott and Eric—who were selected to receive the 2017 awards from the Midwest Chapter. The Stepanovic name may sound familiar as their mother, Lynn, is purchasing manager at Major Wire, Inc., and their father is the global strategic sourcing manager at Magnum Metalsource. Also, Scott was a recipient of the award in 2015. This time, he and his younger brother, Eric—who will also go to Loyola University Chicago, to study Eric Stepanovic finance—were both chosen. Fort Wayne Metals’ Dennis Rohrs, part of the selection committee, explained the choices. “It was clear to me that the Stepanovic brothers were outstanding candidates for our scholarships. I was mindful of the perception that we would be giving both scholarships to recipients in the same family, but they truly are outstanding candidates. After reviewing Scott Stepanovic their applications, I remarked to a colleague that I would like to meet the parents of these young men since I believe the apple doesn’t fall too far from the tree. Congratulations to the Stepanovic family!” Lynn Stepanovic was thrilled at the news. “Many thanks to the Midwest Chapter for recognizing both Scott and Eric for their achievements in high school and college. They have both worked very hard, and having that acknowledged is truly an honor!”

The Midwest Chapter has now awarded 18 scholarships since the program started in 2008, with its annual golf tournament a key “driver” for making that possible.
A good day for the Midwest Chapter golf tourney, and for a good cause The Midwest Chapter returned on June 16 to West Chicago, Illinois, to stage its 15th Annual Golf Tournament, and while the forecast had been iffy, the weather golfing gods were generous as it turned out to be a perfect day at the St. Andrews Golf & Country Club. The team of Jamey Ford and Doug Grover (Chemetall), Doug Hoersten (Leggett & Platt) and Bob Tulloch (Ivaco) shot a six under par 65 to walk away with top honors. Contest winners included the following. Closest to the Pin: Dan Borst; Tom Ruschek (Keystone); Jamey Ford (Leggett & Platt); and Steve Schultz (Lake Cable); Longest Drive: Jamey Ford (Leggett & Platt); and Bob Bender; Accurate Drive: Dennis Ryan (Kreuger Steel & Wire); and Travis Canfield (Suzuki Garphyttan). “It was a very busy day, but all in all a very successful outing,” said Kevin Sopczak, Leggett & Platt, who organized the event. “It’s hard to believe that this was the 15th Annual WAI Midwest Chapter golf outing,” said John Dabbelt, Fort Wayne Wire Die, Inc. “It was good to see some old friends and meet new acquaintances.” Key sponsors for the event included Beta Steel (2), Charter Steel, Ladky Associates Foundation, Lake Michigan Metals, Rio Tinto, Teknikor and Western Engineered Products. Other sponsors included Breen Color Concentrates, CASMI, D & S Wire Inc., Fort Wayne Wire Die, Krueger Steel & Wire, Leggett & Platt, Major Wire, OMCG, Inc., Omnisource Corporation, P & R Specialty, SACO AEI Polymers, Inc., Sonoco Plastics, Suzuki Garphyttan Corp. and Worth Steel and Machinery.

Chapter president makes pitch for players at the WCMA golf tournament New England Chapter President Derek Olson was among those who took part in the recent golf tournament of the Wire & Cable Manufacturers Alliance (see report on p. 17). Speaking to members at the dinner following the event at the Wethersfield Country Club, Olson encouraged the players to continue their generous ways by taking part in the chapter’s 23rd annual tourney on Sept. 12. Below he discusses the upcoming event. WJI: The chapter went to a new golf course last year and is now returning: what makes it a good site? What was the overall reaction to it? Olson: One big reason for moving to the Golf Club of Avon is that it has a 27-hole course, which allows more golfers to play while speeding up the pace of play. The course is one of the best groomed in New England, with some of the nicest fairways around. It can be very challenging, but due to the scramble format you don’t have to be a golf pro to really enjoy the day. We went from a limit of 144 to as many as 200 players without any marathon waits. At the same time, we don’t want people to wait till the last minute to register, because we have to finalize our arrangements long before Sept. 12. WJI: How important is this event to supporting the chapter’s scholarship fund?
WCMA Director Ed Fenton watches as Derek Olson reminds golfers that another tourney will soon be held. Olson: 100% of the proceeds go to our Chapter Scholarship fund. We have given out $56,000 in scholarships to date. Last year, five children or grandchildren of members received $2,000 each. The long-term goal is to have the scholarship fund be self sustainable. WJI: Why should companies want to contribute prizes for the auction or sponsor a hole or specific prizes? Olson: It’s a great way to give back to the industry and to get your company name out there. The exposure to wire and cable industry professionals in New England is unmatched.

WIRE LINK REPORT Bruce Jones with Plant Manager Bob Macario in front of the iconic wire rope flag outside of Bridon Bekaert.
2017 Wire Link Scholar Report By Bruce Jones, photos by John Drummond As a technical account manager for British Steel, understanding the process of making steel into wire is essential in supporting the wire rod business. My major responsibility in this role is the sale of material into the U.S. When making decisions for new products or new customers or even for a change in supply, it is just as crucial to have knowledge of downstream processes. This is something that is recognized by The Worshipful Company of Tin Plate Workers alias Wire Workers and the Wire Association International through the creation of the Wire Link Scholarship, which I was lucky enough to win, and resulted in an experience I will never forget. I was lucky to be able to spend this trip with John Drummond, a WAI Past President who also happens to be the president of the Wire Foundation, which also supports the program. Having spent his career in various roles in the wire industry, John has a great deal of knowledge. Over my two weeks in the U.S., he shared it with me, while making sure that I also had a most enjoyable stay in the States. My journey began on Friday, April 28, when I landed in Boston, Massachusetts. After a short evening, shaking off the jet lag, the following morning was spent exploring some Colonial history on Boston’s famous Freedom Trail, where I saw how a spot of tea led to the American Revolution. The agenda also included a visit to Fenway Park for a baseball game between the Boston Red Sox and the Chicago Cubs, with the visitors winning a close game with the help of a couple of double plays. A big thank you to Gem Gravure’s David Gemelli for donating 36 | WIRE JOURNAL INTERNATIONAL
the tickets. The next morning, we traveled to Fall River to see Battleship Cove, where I got to step foot on the USS Massachusetts (a ship similar to the one my granddad served on in WW II). John’s knowledge of the history really brought the static battleship to life. However, it was really John’s brother-in-law, Ed, who most impressed me that day, by serving up a lobster meal to remember! On Monday, May 1, we climbed into John’s truck and battled the I-495 traffic en route to East Granby, Connecticut, for a tour of RSCC Wire & Cable, part of the Marmon Group. Having never seen nonferrous products or processes before, I wasn’t sure what to expect. I soon realized that there are many similarities in cable production between steel, copper and aluminum. Vice President of Operations Luke Thompson explained the paying off, back twisting and cabling process. While what I saw was different, it did provide me a broader understanding of processes in general. I was particularly interested in the engineering solutions the company had developed to service the logistical and technical needs of sensor cables for the oil industry. We also visited the Innovation & Technology Center, where Marmon staffers—Senior Chemist Dan Masakowski and Chief Innovation Officer Rob Konnik—provided an interesting insight into the development of the polymer jackets that are critical in the success of the company’s extreme environment cable products. I had plenty of questions for Konnik, who explained the differences between the processes and why they are required for the different applications. From there, we went to visit Luvata—the Finnish translation of that word is “to promise”—in Waterbury,

Connecticut, at one of their special products sites. The main products produced at the site are electrodes, superconducting cables and photovoltaic ribbons. These are used in applications requiring high magnetic fields such as NMR spectroscopy, MRI scanners and nuclear fusion reactors as well as the large Hadron collider. We were greeted there by President James Lajewski and Technical Manager Robert Schaedler, who gave me a crash course in superconducting principles before the plant tour. They explained the theory behind the product, and I was in awe at the cutting-edge process they had designed to produce a vast array of assemblies. We also toured the laborato-
ry, where I was shown how product quality is ensured through rigorous testing, a consideration that is close to my role. On Tuesday, May 5, we drove to the FreeportMcMoRan Norwich rod and wire plant, also in Connecticut. Our tour guide was Plant Manager Jim Hodson, who explained the operations. The plant has two main product lines, and I got to see the continuous casting equipment on a down day. That turned out to be a plus as I got a better look at the equipment, and could ask questions about the differences from the same process for continuous casting of steel, which I had previously learned

WIRE LINK REPORT Plant Manager Jim Hodson was the guide for the tour of the Freeport-McMoRan copper rod mill. during a technical rotation at British Steel. The concept of melting, casting and rolling the material in one step is where the processes differ greatly and really takes advantage of a single product analysis. The second product line is the 99.99% oxygen-free rod, produced electrolytically in a sealed environment. That afternoon, we drove to the Nucor Steel wire rod and mesh plant in Wallingford, Connecticut. There, Operations Manager Jon Rowley proved to be an insightful tour guide. We discussed the British Steel’s four-strand rod mill and Nucor’s single-strand mill. While the two

plants differ greatly in design, execution and product types, they share the ingenuity of the technical and manufacturing teams in improving the capability of the process. I was interested in how Nucor handled the payoff process, knowledge that I believe can be applied to help benefit our customers. This is as concrete an example as you could ever ask for to show the value of the Wire Link Scholarship program. Due to the rich itinerary planned by John, who is most certainly a morning person, Wednesday, May 3, was the first of a few early starts on the road. We drove to Bridon Bekaert in Scranton, Pennsylvania, and our first stop was at the wire rope plant, where we met Plant Manager Bob Macario, who provided a most insightful and relevant tour. I saw the stranding process that produces ropes used in a wide array of applications. The highlight was when the machines were stopped, allowing me to see a “freeze frame” of the payoff, stranding and drawing processes that produce varied assemblies, lengths and diameter ropes. I got a shop-floor education on how swaging, double-twisting and optimizing lay length each work. That experience was invaluable as it will help me better understand when customers discuss their stranding operations and requirements. We then went on to the wire drawing facility, where by chance we arrived alongside a contingent from my homeland: a team of managers from Bekaert, the new owner of the Bridon group. The tour, led by Plant Manager David White, first looked at the “recipe” of wire rod, which was similar to that which British Steel produces. Then, there was a walk through the annealing and lead patenting steps. I was very interested

AWT Machinery promoted welding technology from South Africa’s Clifford Machines & Technology (CMT) at Interwire 2017, most notably a new mesh welder that is especially flexible. CMT, which continues to deliver state-of-the-art, high quality, reliable and efficient machinery, recently supplied a high-production fencing mesh welder to a large reputable mesh producer. The mesh line, model MWPA34 for direct AC welding, is extremely versatile, offering the ability to produce a large range of mesh fencing products along with other more general purpose wire mesh. What makes this current line superior to the market is its ability to weld the new 4D high security mesh, which features alternating crosswires on the front and back of the mesh panel.

The value of doing so, explained AIM President Constantine Grapsas, is that it provides information about processes as well as profitability that answer such questions as: are you utilizing your capital investment in the most efficient manner? is there a problem with your bending operations? does it take too long to set up your production? what was produced? when? how long did it take? which shift was more productive? which bender had the most troubles? what was the total wire weight used yesterday, last week, last month, etc.? and how many pieces of part “A” did we produce last month? The new AccuTrack technology platform can answer all the above questions. It remotely monitors all AIM CNC benders in real time, while managing equipment utilization, uptime, idle time and many other production properties. The system, which automatically “discovers” all of the AIM equipment in the same network, can start working in minutes. It has easy-to-comprehend graphics that enables a user to pinpoint problems while providing production reports in a touch of a button.

Used equipment may be a perfect match for new manufacturing needs There’s no finish line to advances in technology, but Erik Macs, director of sales for Wire and Plastic Machinery Corp., believes that used and refurbished equipment can also be a good way to go for many manufacturers seeking more capacity. Below he explains why. New equipment manufacturers around the world can provide the latest and greatest equipment for wire and cable production. Typically, that comes with a minimum one-year warranty for parts and labor, and a customer can expect to get years of production capability. Those are definite pluses, only it can come with a staggering price tag in some cases. If cost is not a factor, then there are a lot of OEMs that would like very much to hear from you. But if the bottom line does matter, you should consider contacting a supplier of used and refurbished equipment—such as Wire and Plastic Machinery Corp. (WPMC)—that purchases surplus machinery and recycles it back into the industry in a refurbished state. The biggest reason for going this route is that the savings for buying a used refurbished machine can be anywhere from 20% to 70% of that of a new machine, the range depending on the initial condition of the used machinery. Another reason is that the delivery time likely will be many months less. The performance speeds may not match the newest technology, but an overall analysis
may find that there are significant advantages to buy refurbished. Technology advances can be critical in certain areas of our industry, but not all processes need cutting edge hardware and software. For instance, there may be no need to replace a tensioning system in a rotating cabler system if Erik Macs it has little effect on overall cable performance. Aside from needing a new screw and barrel, most extruders can easily be resurrected. Most machinery will require an electrical overhaul. Sometimes the mechanical enhancements and upgrade of electronic controls allow the refurbished machinery performance to exceed that of the original OEM. However, one other consideration is that newer technologies can also add to maintenance concerns and cost. For all the above reasons, it could be time well spent for a customer to find out what may be possible with refurbished equipment. WPMC can offer a wide range of equipment from its five U.S. warehouses, and offer flexible options. For more details, go to www.wireandplastic.com.

Davis-Standard USA Davis-Standard’s display at Interwire 2017 included the company’s new cut-feed station, which is ideal for low-voltage wire and cable processes for insulating applications. Engineered for efficiency and longevity, this unit facilitates timely transfers between one take-up to the other while minimizing operator involvement. This expedites the take-up reel change process during insulation and enables manufacturers to boost outputs. The robust design features a deflection pulley arrangement and helper caterpillar with Davis-Standard’s Orlando Martinez by a cutting system to streamline the company’s cut-feed station. the insulation process and ensure quality. The pulley arrangement sits between two portal take-ups. It includes pulleys for round cables with integrated clamping, feeding and cutting devices. A pre-programmed length of cable can be pulled out of the accumulator enabling the operator to affix the end of the cable to an empty reel after being cut. Pneumatic clamping during take-up changeover is delivered via the helper caterpillar. The caterpillar pulls the cable from the accumulator, transferring it from one take-up cut-feed station, up to the other. Other advantages include adjustable vertical and horizontal guiding rollers at the inlet and outlet sides of the machine, and adjustable upper and lower belts on pneumatic cylinders with pressure rollers. An AC gear motor delivers power with an automatic “off” feature when the winding drives are activated.

The traditional form of tape pads is the flat pad, or pancake type. But more and more cable makers started using traversed pads, also called coils or spools. These hold two to three times more tape, and are more stable and less likely to collapse, which is especially important for narrow tapes. Usually, tapes narrower than .625 in. or .500 in. are only available in traversed pads. One problem that can happen when tape is paid off a traversed pad is that the angle the tape exits the pad gets worse the closer to the pad edges the exit point is. This
Gimax Srl Italy Cable Consultants Corp. USA At Interwire 2017, Gimax Srl showcased the company’s expanded range of equipment for the wire and cable industry. Per Gimax, the company’s redesign of its entire range of drawing equipment has proved to be very successful, resulting in a solid increase in sales as well as penetration of market segments, including some that were little known to the business. One such example is specialized cobalt-based tubular wires, which can be produced on Gimax’s dry TRD line, or titanium wires drawn down to 0.2 mm (AWG 32) on the company’s new TRS wet draw line.

exit angle may stretch one edge of the tape, or the other, and that lowers the quality of the taping process. The new version Dynamex displayed eliminates this problem. It deploys a patent-pending device, called the “ZERO-ANGLE TAPE EXIT,” which is housed in the “black box” in the photo. This device makes the tape exit the traversed pad perpendicularly across its full width, which leaves the device at a fixed location, in the center of the pad width. This technical advances may be available in the future as a stand-alone to retrofit existing machines. For more information, contact Ben Bravin at tel. 310-329-0399, sales@dynamex.com.

The TRS is a totally non-slip wet drawbench, where the lubricant is “sprayed” onto the die, die box and capstan. Several of these are now in production for aluminum welding wire as well as ferrous wire. The TRS has a reduced footprint as well as easily accessible parts and components that offer cost savings in terms of floorspace and labor (operation and maintenance). All those advantages help to decrease downtime and consequently increase productivity. The TRD line also includes a dry drawbench with vertically positioned capstans (horizontal shaft). This nonslip line offers further benefits than can be had on more traditional lines that use horizontally mounted capstans (vertical shaft). The maintenance of this line is a lot easier since the machine is far more accessible, particularly on the rear of the line where the motors, gearboxes, piping, cabling, etc., are housed. This line is designed to always maintain the temperature under constant control through an extremely efficient water cooling circuit of the capstan and the dies.

Each cage and capstan is driven by a separate motor, and the pitch can be adjusted freely, which allows a rotating speed as high as 300 rpm; the cage’s transmission is by reducer from motor instead of by a timing belt, with cage loading/unloading driven by a cage motor with a low-speed mode; the pintle on the cage is opened pneumatically and clamped by a spring device with a mechanical safety lock system, which increases the cage rotate speed without an air-package system; the position-point fixing design guarantees an accurate match for the cage and bobbin loading and unloading system, and the loading and unloading device can be either motorized or hydraulic; energy generation during braking can be fed back to the power system to achieve further energy-saving purposes; the electric system can be run by a remote mode, and a wire break can be displayed on the touch screen to show the bobbin position on the cage; the intelligent controller

Shanghai Xiaoxuan M&E Technology Co., Ltd. China At Interwire 2017, Shanghai Xiaoxuan M&E Technology Co., Ltd. (SXME), extolled the multiple advantages offered by the company’s new wire drawing machine. Chen Shenpei, SXME’s vice general manager, said that the most important aspect about the machine is that it is powered by a servo motor that is built in the capstan. In the photo, he points out the comparative advantages that this results in. The direct connection eliminates the need for a gear box, belt and brake as well as for an electric cabinet. Instead, the system is truly plug and play. The

result of the above advantages is that there are significant savings: the system uses 20% less energy, requires half the space and maintenance is reduced by 40%. The SXME wiredrawing system also has Industry Internet of Things (IIoT) intelligent management. It allows the use of a mobile phone to track a product for just about any production aspect, from who is working on it, the current work status, the machine’s productivity for a given period, the output of certain diameters in a certain period, power consumption per ton in a certain period, the maintenance status, and so on. Another characteristic is that if the emergency stop button has to be used, the wire on the machine will not break because of the way the system is controlled. SXME began research on the new drawing machine in 2013, and the first model was finished in 2015. To date, more than 50 drawing machines have been sold and are now in production.

WAFIOS USA In the shape of iQsmartbend, WAFIOS has developed a patented, award-winning software solution designed to optimize bending processes for wire and tubes that it showcased at Interwire 2017. Below, it discusses the thinking behind its product development. The phenomenon of vibrations can be observed in almost every area of our daily lives. In some cases it is undesirable and may even be dangerous, but in others, it is the intended result of a conscious action. Intervening
Vinston US Corp. USA At Interwire 2017, Vinston US Corp. showcased the company’s new hybrid bender, the CMM-8-600 WB. The eight-axis table bender can deploy up to three servo-driven slides that can be used for various stabilization and completion tasks. The eight-axes model supports wire sizes of up to 6 mm for soft wire and 4 mm for spring wire. The table is adjustable on the Z axis based on the need of the wire form. Smaller components can be produced with speed and stability when the table is close to the machine body. Larger components can be cleared by extending the table away from the machine body. The vertical movement of the table along with the servo slide assist facilitates the completion of many complex wire forms with ease. An example would be the end hook for a wire form, which would be difficult to complete with a standard tabletop bender. The servo slide, in this case, can stabilize and hold the wire in place while the end hook is completed. The new bender will utilize the same software architecture as Vinston’s wire formers, making cross training

Thomas Madelung, regional sales manager, by the company’s BM30 wire bending system. measures can be put in place in both cases, as a means of either absorbing (or at least minimizing) vibrations in the former case, or generating (or amplifying) them in the latter. The pendulum of a grandfather clock and the swinging-out motion of the seats on a fairground swing ride are both examples of controlled, stimulated vibrations. One example of where absorption can be found is in the tuned mass dampers used in high-rise structures. Installed in buildings such as the Taipei 101 tower, which measures 500 meters in height, dampers of this kind absorb building vibrations—particularly those caused by wind, but also those caused by earth tremors or human influences— and prevent the building from rocking. As a result, they serve a dual purpose: both ensuring the building remains safe and providing comfort for its inhabitants. Another example can be found in construction cranes. The natural vibrations that occur in the boom, cable and load need to be balanced out so that the boom can position the load in exactly the right place. Then there are the controlled and guided vibration movements created in a wrecking ball. Analytical calculations and control systems can be used to minimize or absorb vibrations in tuned mass dampers, wrecking balls, and cranes, but the vibrations that affect CNC machines are subject to many influencing factors that rule out methods of this kind.
FEATURE
When long wire and tube parts are being shaped, the workpieces frequently vibrate heavily due to the process. To hold the required quality usually means manually adjusting (in other words, slowing down) each bending step, a time-consuming, cost-intensive process. Generally, conventional criteria such as flexibility, output rate and quality are used to assess how profitable a wire-bending machine is. Often, however, it is not the machine that is the limiting factor, but rather the geometry of the bent part. Significant vibrations can occur in long bent parts with slim geometries as the process means that an increasing amount of the bent part’s mass hangs freely in the air each time a bending step is completed. These vibrations cause unwanted deformation in areas of wire that have already been bent, and excessively strong swinging motions can also lead to the wire springing out of the tool that is open at the top: a machine operator has just two options: either reduce speed or factor in waiting times. Both strategies, however, impact output. Up to now, it has not been possible to find a solution in which an optimization algorithm, operating by means of a direct link between the production machine and a computer, is able to automatically reduce or even eliminate the natural vibrations that the bent part experiences. WAFIOS, we are pleased to note, through iQsmartbend, has achieved this. For more information, contact WAFIOS at 203-4815555 or sales@wafios.us.

Morgan-Koch’s Al Kozlowski and Marc Heberlein by the WiTech wire rod sander displayed at Interwire 2017.
WiTech Wire Technologies Srl Spain/USA At Interwire, WiTech Wire Technologies, represented in the U.S. by Morgan-Koch Corp., displayed the company’s updated sander, Model SEZ-2-450, for steel wire rod. The single-head machine, first introduced in 2016, has a new two-roller flyer system (2-RFS). The abrasive belt rolls are extended by 50% for use with high-performance sanding belts (single 450 mm or double 200 mm for rough/fine processing) that can operate at speeds up to 4.0 m/s. The roll diameter, 12% larger, allows for excellent belt tracking. A new wire guiding arm provides fine adjustability to either guiding rails or guiding rolls for extremely straight and vibration-free wire guidance. The SEZ-2-450 has a new bearing system with a higher dynamic load for significantly longer lifetime and reduced bearing wear through the center support of sanding belt rolls. It offers excellent lifetime because of tungsten carbide flame-sprayed sand belt rolls, and the modular body provides easy machine access. There are no problems with no sanding dust in the motor room because of the use of water-cooled motors, and if a problem occurs, an emergency stop for the line is simple. Earlier this year, WiTechs carried out a test series with some well-reputed manufacturers. The in-line model had to meet varied customer requirements for steel wire rod qualities. That included sizes, from 3.0 mm to 13.0 mm, and different surface cleaning and abrasion processes, and for different market sectors: automotive, railway and high precision wire rod applications. The initial results were quite good, and a second series of tests is planned for September. WiTechs will be pleased to share the results with you and welcomes your support and any input/ requests your company might have. The booth also included a WiTech wet cleaning and coating machine, model HSBE-3301, that provides substantial energy savings by using up to 45% less compressed-air, thanks to innovative proportional valve technology. It offers a higher layer support, up to 30%, due to the intelligent combination of hot rinsing and coating. The tank is optimized for energy-efficiency, with an innovative double-chamber system for excellent coating results. It has automatic filling control via touch-panel with user-friendly visualization, a compact design with an

Off-line ‘purity detector’ offers testing benefits for material inspection/analysis At Interwire, Sikora AG exhibited its on-line PURITY CONCEPT system, but the company also displayed an off-line model for inspection and analysis of pellets, flakes and tapes. The off-line models are designed for smaller material throughputs as well as for production lines where sample testing is sufficient, or the control of incoming goods is required, said Harry Prunk, a member of the executive board at Sikora AG. Depending on application and expected contamination, the systems—equipped with X-ray technology (X), Infrared technology (IR) or optical sensors (V)—are used for the detection and analysis of contamination in plastic material. 60 | WIRE JOURNAL INTERNATIONAL
The operation is simple, Prunk said. “If we take, for example, our laboratory PURITY CONCEPT X with X-ray technology, it inspects up to 3,000 pellets (equal to 200 ml) that are placed on a tray. Within seconds, these pellets are inspected for contamination. Contaminated pellets are optically highlighted for further analysis.” Prunk explained that, for cable manufacturers, the use of inspection, sorting and analysis devices is not a decision for an online or an offline system. “We see in the industry that for comprehensive process optimization, cable manufacturers combine the online inspection and sorting system PURITY SCANNER with an offline inspection and analysis device of the PURITY CONCEPT system. This interaction ensures the monitoring of material purity as well as the creation of a database to avoid contamination in the future. Quality assurance cannot be any more professional as with this combination.” Contact Sikora AG, www.sikora.net.

The latest OFC 52/52i development is focused on the ring-marking process and how to achieve higher production speeds. In the ring marking process, the marks are printed on the fiber with a high-speed ink jet and the marks are dried with heated airflow before the color is applied to the fiber. Using solvent-based ink makes the system very cost-effective for the customer. High-quality black marks are printed at equal intervals and the interval of the marks is accurate for ramps as well. A wide range of mark patterns can be produced. The high-speed machine vision system ensures the quality of ring marking. It inspects mark quality and helps customers to reduce costs at production facilities through reduced rework and quality assurance.
In addition to new coloring lines, the benefits of an improved ring marking process can be gained with old coloring lines. The Nextrom ring-marking process can be an upgrade for all coloring lines, even for non-Nextrom lines, as a standalone unit. The system can process high-speed coloring at speeds of up to 3000 m/min, with ring marking up to 1000 m/min and upcoating up to 900 m/min. Contact: Nextrom, www.rosendahlnextrom.com.

Abstract
A refinement is offered that accounts for the effect of increased ambient temperature on temperature rise. A well-known function is identified as the factor used to translate the temperature rise at a reference temperature ሺʹͲԨሻ to a temperature rise at any ambient temperature.
This paper builds on the previous year’s work which attempted to establish a series of best practices when evaluating the temperature rise of bundled cable. In the previous paper a simplified model was introduced and used to characterize the temperature rise of cable bundles supporting PoE-style applications. In this paper, the simplified model is re-interpreted in terms of the more elaborate CENELEC model before being recast into a concise matrix model. The use of the more elaborate models suggests a change to the earlier recommendation that only center-of-bundle measurements be recorded. The introduction of temperature measurements on the surface of the bundle permits different methods of determining the coefficients used to characterize bundled cable temperature rise.
The assumptions that were used to develop the iteratively solved CENELEC model are employed to establish a closed form matrix model describing the temperature rise of similarly shaped cable bundles. Next, the assumptions on the distribution of temperature within the bundle are examined and a refinement to the matrix model is offered resulting in a nearly equivalent model that takes into consideration the temperature at any point within the bundle.
The topic of practically measuring the temperature rise in bundled cable is also discussed. The one-measurement-onmultiple-bundles method discussed last year is reviewed. A case study is offered to demonstrate the suitability of the method for determining the fit coefficients that estimate the maximum temperature of the cable bundle. The same example is used to demonstrate that in the absence of a previously identified error correction and/or data from the surface of the bundle, the obtained coefficients are unlikely to represent the temperature profile of the complete cable bundle. An alternative measurement method is implemented and shown to be effective but still include errors which jeopardize the interpretation of the data. A method of accounting for these errors is established and when implemented, results in harmonized coefficients regardless of the measurement method chosen.
It is shown that a previously introduced error-correction method can be extended to surface temperature measurements resulting in good agreement between the different methods of determining temperature rise coefficients. Finally, the coefficients determined through this process and in use in standards committees are used to extend the simplified model in the direction of non-round cable bundles.

1. Introduction
A previous paper attempted to publish some best practices for establishing the temperature rise of bundled cable supporting a constant DC current [1]. Though not explicitly covered in the paper, the goal was to provide methods of determining the temperature of the cable bundle used to support PoE-style applications. In the year since the last paper, the discussion surrounding the use of remote powering and cable heating has continued. While many of the practices introduced in the last paper continue to be useful, there have been further developments leading to a deeper understanding of the topic. This improved understanding has benefited cable manufacturers, standards organizations and customers alike.
Finally, the simplified model and the coefficients mentioned above are used to examine the temperature rise of nonhexagonal cable bundles. This is carried out by reinterpreting the simplified model in terms of an integral rather than a polynomial. An equivalent form of the simplified model is developed as an integral around a circle. Manipulating the path of this integration makes possible the prediction of the temperature rise of bundles whose cross section deviates somewhat from the traditional hexagonal bundle.
2. Cable Heating Models 2.1 Existing Models
This paper discusses some of the topics which, while touched upon in the last paper, have been developed further contributing to a deeper understanding of the temperature rise of bundled cable. It begins by reintroducing the basic model used to describe the temperature rise as a function of the number of cables and current supported by the conductors in a hexagonal bundle. This basic model employed by TIA is compared to the CENELEC model and the two are shown to be equivalent in structure but to differ in the way they empower the user to predict temperature rise.

In a previous paper, experimental data was gathered on 7, 19, 37, 61 and 91 cable bundles driven using five different current levels. The data from this and other similar bundles was used to verify the behavior of cable bundle temperature rise as a function of both current and number of cables. One conclusion from this investigation was that the temperature rise at the center of a cable bundle was best approximated using a function of the form οܶሺ݊ ǡ ܰǡ ܫሻ ൌ ሺ݊ Τͺሻ൫ܥଵ ܰ ܥଶ ξܰ൯ܫଶ

2.3 Use of the Models at Other Than Ԩ.
The model described by (1) is intended to be used at an ambient temperature of ʹͲԨ. While the temperature rise of bundled cable supporting PoE-style applications is predominantly a function of the energizing current, changes in ambient temperature also affect the temperature rise of the cable bundle due to a change in the resistance of the conductors. It would be convenient to have a method of determining the temperature rise at ambient temperatures greater than ʹͲԨ. This can be accomplished by recognizing (1) as a form of Joule’s law and expressing the temperature rise as a function of current and dimensional parameters (grouped into a function ݄ሺܫǡ ܰǡ ݊ ǡ ݀ሻ) and resistance or

The model described by (2) has no apparent accommodation for operation at temperatures other than 20C but does include the term for conductor resistance as one of its parameters.

In addition to the form of the model, strategies for efficiently evaluating the temperature profile of cable bundles were proposed. Specifically, it was argued that the temperature rise of a cable bundle of any size due to any current energizing any number of pairs could be estimated by measuring the temperature rise of two differently sized bundles driven using relatively high current levels on an arbitrary number of conductors. The data gathered in the study relating temperature rise to the number of cables in a bundle for different energizing current levels is represented in Figure 1.

A plot of the three solutions obtained using the iterative, matrix and refined matrix models is provided in Figure 2 for the case of Cat 6 cables in bundles ranging from 1 to 100 cables3 and shows that the three solutions are nearly identical. To numerical precision, the iterative (2) and matrix (9a, 9b, 9c) model provide the same results. The refined matrix model described by (9a, 20, 9c) predicts a slightly smaller temperature rise than the other two (Figure 3). One might conclude that the refined matrix model requires full layers to determine the function Ý‚áˆşâ€ŤÜŻâ€Źáˆť. In truth, all of the models are best suited to bundles comprised of full layers with points intermediate being interpolated versions of the full layer cases. This point is exploited in section 4 of this paper.

While equation (9) eliminates the need to iterate, the result represents an approximation because the resistance of the bundle is not appropriately described by equation (7).

3. Practical Measurement Concerns 3.1 Review of Measurement Procedure
The need to establish the temperature rise of differently sized bundles of different categories of cable means that a number of measurements need to be carried out. In practical terms, this means establishing the two terms which largely describe the temperature characteristics of a cable bundle. In the case of equation (1) the two terms are â€ŤÜĽâ€ŹŕŹľ and â€ŤÜĽâ€ŹŕŹś . In the case of (2) the two terms are ߊ௧௛ and ߊ௨ .
Confining attention to the case of (1) and in an attempt to reduce the number of required measurements, a two-measurement method of establishing the behavior of a particular type of cable was proposed. The first measurement recorded the temperature difference between the center of a cable bundle (of ܰଵ cables) and the ambient, or οܶଵ . The second measurement was similar to the first but was carried out on a cable bundle of ܰଶ ŕľ? ܰଵ cables resulting in οܶଶ . From these two measurements the coefficients â€ŤÜĽâ€ŹŕŹľ and â€ŤÜĽâ€ŹŕŹś necessary to characterize the behavior of a type of cable (bundle) could be established using ܰଵ â€ŤÜŤâ€ŹŕŹś ‍ܼ‏ ྤ ଵ൨ ŕľŒ ቈ â€ŤÜĽâ€ŹŕŹś Ü° â€ŤÜŤâ€ŹŕŹś ଶ

3.2 Intra-bundle Measurement Correction
In the previous paper, the temperature rise for differently sized cable bundles was established using a comparison of two independent measurement methods. In the first, thermocouples located at the center of the bundle were used to gather temperature data. In the second, the resistance of the center conductor in the cable bundle was monitored and the change in resistance was used to establish the conductor temperature. A systematic error between the two methods was discovered which correlated with the size of the cable bundle under investigation (Figure 5). The collected data showed that for 7 cable bundles, the deviation from agreement between the two methods is as much as 5% while the deviation between methods for a 91 cable bundle is reduced to a value closer to 3%. Believing the change in resistance method to be the more accurate of the two, the thermocouple measurement method underestimated the true temperature change by an amount which depended linearly on the size of the cable bundle.

This procedure was/is effective at establishing the coefficients necessary to predict the temperature at the center of the cable bundle and for bundles similar in size to the values used to establish the coefficients. However, because both of the measurements were carried out at the center of the cable bundle, the coefficients â€ŤÜĽâ€ŹŕŹľ and â€ŤÜĽâ€ŹŕŹś are predisposed to accurately predict the center-of-bundle temperature. In cases where errorcorrection is not suitably applied, the resulting coefficients incorrectly predict the temperature on the surface of the bundle.

errors present in the exterior temperature data which also need correction. The need for error correction is also supported when one considers that the thermocouple only tangentially contacts the surface of the cable jacket (Figure 7). Thermocouples are intended to be used in regions where the thermocouple junction is surrounded by a constant temperature (not at the boundary between two media). Therefore, it is conceivable and even likely that the thermocouple is reporting a temperature which is less than the temperature of the surface of the bundle. An argument can be made that any correction introduced should (like the correction used for the temperature data gathered inside the bundle) be a function of the bundle size because as the diameter of the bundle increases, the boundary between the ambient and surface of the bundle more closely approximates a plane reducing the temperature gradient around the thermocouple.

Figure 5. Ratio of observed temperature rise using the thermocouple method to calculated temperature rises using the change in resistance method If this error correction is applied to the case considered in Table 1, the temperature rise data or the quality of fit does not change significantly. What does change is the shape of the curve dictated by the data points. This change in shape, though subtle allows for the calculation of coefficients [â€ŤÜĽâ€ŹŕŹľ ŕľŒ ͲǤͳͳ͝ and â€ŤÜĽâ€ŹŕŹś ŕľŒ ͳǤͲ͝] that better approximate the value of ÎżÜśŕŻŚŕŻ¨ŕŻĽŕŻ™ŕŻ”ŕŻ–ŕŻ˜ . For illustrative purposes, Figure 6 contains the corrected data alongside the original uncorrected center-of-bundle data and fits (in gray and dotted lines). In other words, a suitable correction to the data obtained at the center of the cable bundle results in a better fit to the data collected on the exterior of the cable bundle. This observation supports the conclusion obtained in the earlier paper.

To a large extent, the fitting procedure with error correction demonstrated on the intra-bundle data improved the prediction of the temperature predicted on the exterior of the bundle. However, there still exists a discrepancy between the data recorded on the exterior of the bundle and that predicted by the linear-with-respect-to-cable-count term in equation (8). Given that the temperature data recorded on the exterior of the cable bundle was gathered using thermocouples similar to those used on the interior of the bundle, one might expect that there are

4. Reinterpretation of the Model
The measurement techniques identified in this paper have been used to develop a set of coefficients â€ŤÜĽâ€ŹŕŹľ and â€ŤÜĽâ€ŹŕŹś describing the anticipated temperature rise of bundled cable in open air and conduit environments. These coefficients and others introduced by other participating companies have been used to establish the coefficients in the latest draft of TIA TSB-184-A. These coefficients were developed for use in the equations of the form (1) or (6) and allow the user to predict the anticipated worst-case temperature rise of a hexagonal bundle of cable operating at 100% duty cycle at steady-state with any number of pairs in each cable energized by the current I in open air or in an enclosed conduit filled to less than 40% by volume.
(28)
While this is useful, there is the possibility that this hexagonal model is also useful for determining the temperature rise of cable bundles that deviate somewhat from the largely hexagonal shape.
(29)
To accomplish this, the hexagonal distribution is replaced with a circular distribution which yields an equivalent temperature rise. The concept of a radius of temperature rise, ‍ݎ‏οŕŻ? , is introduced for this purpose and can be visualized by setting the area of a circular region equal to the anticipated temperature rise or ŕŹśŕ°—
For clarity, the uncorrected temperature data gathered from the center, surface and some distance from the bundle originally provided in Table 1 are repeated after error correction in Table 2.

In this way, the temperature at the center of the bundle is determined by summing the contributions of small wedgeshaped slices of the overall bundle analogous to integrating around a circular path to determine the area of a circle. This expression can be used to express (1) in the form of a double integral which is independent of ‍ݎ‏ο� , or

Figure 8 contains a plot of the data and fit when both the intraand inter-bundle data have been error corrected using (25, 28, 29). Note that even though the gathered temperature data has been adjusted upward, the predicted temperature rise for a 100 cable bundle is the same and (for bundles larger than 100 cables will be less than that predicted using the lower in magnitude but uncorrected data.

This error correction can be implemented via a trial and error process5. The determination of the coefficients can also be improved by considering more than one bundle size of the same type of cable bundle.

Table 2. Error corrected data from 61, 37 and 19 cable bundles of Cat 5e
The argument made surrounding Figure 7 suggests that the thermocouple readings taken at the bundle surface may also be in error and that a correction to their values may be in order. This possibility is also supported when the data from the bundle surface in Figure 6 is considered. Keep in mind that there is no established second method for determining the true temperature at the surface of the bundle such as was the case with the change in resistance method of determining the temperature at the center of the bundle.

with no increase in inputs or loss of accuracy between (1) and (31). Recasting the polynomial in (1) as a double integration of the form ݂ ሺܰሻ݀ܰ݀ߠ seems like a complicating step but conceptually, it permits the function ݂ሺܰሻ to be used as the integrand along different non-circular paths of integration. Each differential wedge ݀ߠ is a contribution approximated by an equivalent wedge in a circular bundle of ܰ cables.
applications. It began by considering a simple model and then compared the model to the more elaborate CENELEC model. The two are shown to be similar in structure but (per the standards organizations which have adopted them) are intended to be used differently. The more flexible and computationally intensive CENELC model is recast in matrix form eliminating the need to determine a solution iteratively. Further, the assumptions used to estimate the resistance of the conductors in the CENELEC model are developed and incorporated into a revised matrix model. This revised model is compared to the CENELC and original matrix model and the three are shown to be virtually identical.
As an example, consider the case of a 19 cable hexagonal bundle formed using Category 6 cables (ܥଵ ൌ ͲǤͳͲͷ and ܥଶ ൌ ͲǤͲ ) with a diameter of ݀ ൌ ͲǤʹͷ̶ ሺǤ͵ͷ ݉݉ሻ. Equation (1) [and equation (31)] predict that the temperature rise of the 19 cable bundle will be οܶሺͳͻሻ ൌ ͷǤͲͻԨ. If the same cable bundle were placed in a tray equivalent in height to the 19 cable bundle but wider such that it accommodated 4 additional cable diameters, a total of 43 cables would fit within (Figure 9).
All of the models considered make use of empirically determined coefficients. These coefficients are obtained by analyzing the temperature data recorded on physical bundles of cable. In most cases, this data is most conveniently gathered using thermocouples. Previous results demonstrated that thermocouple data gathered at the center of a cable bundle underestimated the temperature by an amount which could be related to the number of cables in the cable bundle. A proposed correction was reviewed and extended to the case of data gathered on the exterior of the cable bundle. The correction was shown to improve the accuracy with which the coefficients predict the behavior of both the internal and exterior temperatures of the cable bundle. Finally, the coefficients determined through this process and the simplified model are used to examine the temperature rise of non-hexagonal cable bundles. This is carried out by reinterpreting the simplified hexagonal polynomial model in terms of an integral around a circle. A change in the path of integration is introduced and the circular model adapted to geometrically deviant cases with results that align with expectations of the physical system.
Figure 9. Rectangular bundle with 43 cables (19-cable hexagonal bundle at center). Equation (1) predicts οܶሺͶ͵ሻ ൌ ͻǤʹԨ. However, the bundle under consideration is no longer a hexagonal (or round) bundle but rectangular in shape. The expectation is that the cable at the centroid of the rectangle would experience the greatest temperature rise [4] but that the temperature rise should be less than if the bundle contained the same number of cables but was more uniformly hexagonal or round. In such a case the integrand and limits in (31) can be modified so that the integration is carried out over the perimeter of the rectangle. An alternative expression for (31) then becomes ଵ
