alloy, the maximum allowable temperatures are between 150°C and 230°C. Peak temperatures may vary between 180°C and 310°C. These conductors have a limited sag effect as compared to others. c) Use of AA1370 or AA1350 (commercially pure aluminium) in H11 temper (85 MPa ≤ UTS ≤ 95 MPa) for the manufacturing of conductors type ACCC (Aluminium Conductors Composite Core). The conductor consists of a carbon fiber wire, with a typical tensile strength of 1500 N/mm2, around which aluminium wires are wound. In order to optimise the filling of the apparent cross sectional area of the conductor, the wires are profiled instead of having a circular cross sectional area. ACCC conductors can significantly increase the capacity of an existing power corridor without requiring the necessary modifications to existing structures, as would be necessary if a larger conventional cable was used to increase the required capacity. Several technical papers have illustrated in detail the various strategies and new technologies concerned with the need for transporting more and more EE within existing infrastructures; therefore we will avoid going deeper into this subject, but we will only add that Properzi, with their specialised machinery and dedicated services, has allowed the cable industry to reach targets that were unimaginable “yesterday”. The application of aluminium rod for mechanical uses is maybe even more demanding and severe than the application for electric conductors. Also in this sector the driving forces are the “perfect three” and the rate of substitution where steel is most often the loser. Yes, aluminium rod is everywhere around us in the form of conductors, and we have good reason to believe that for the foreseeable future this market trend which requires increasingly complex alloys will grow at a steady rate; this will be the future. Properzi can offer a complete range of aluminium rod plants, from the smallest ones sized for 10,000 tpy to the extra-large ones sized for 100,000 tpy. The complete range of Properzi CCR Al rod lines is displayed in Table B. For SMALL and MEDIUM plants Properzi has tailored the very efficient Aluminium International Today
vertical melting furnace called “Vert-Melt”. This furnace is not available for LARGE and EXTRA-LARGE CCR rod lines since, in general, such plants are equipped with large holding furnaces which are fed with liquid metal coming from pot lines. Properzi also has a very wide range of coilers for rod packaging. In summary: � the classic package of 2.5 tons, both in European and American standard � the jumbo coiler, designed to produce coils of 3 tons, again in European and American standard � the super-jumbo coiler which has been delivered mainly in North America where the coils weigh 3.7 tons and have an internal diameter of 780 mm All the above are solutions for tight coils either in random or pitch-topitch mode. Also available for small and medium CCR lines is the packaging in loose coils for in-house transportation and use. In case any packaging for export is required, Properzi offers an off-line recoiler. In addition to the Properzi “classic” aluminium plants described above, some years back Properzi launched a new generation of CCR lines called E–Type (where “E” stands for Essential). Such lines, ranging from 1.6 tph through 4 tph, have been specially designed for producing EC grade and eventually AA 6201. The rod is generally coiled in loose coils, ideal for inhouse use of the produced rod. The annual output rate of such CCR lines ranges from 10,000 tpy through 26,000 tpy. The furnace set is also part of Properzi’s supply. We have talked about machinery but the following services and/or features offered by Properzi should not be neglected as a part of the supply package: � specialised engineering for layouts, foundation drawings, and for tailoring special technical solutions, if requested � lowest OpEx (Operational Expenditures) � highest OEE (Overall Equipment Efficiency) � first class components (hydraulic, pneumatic, electrics, etc.) and user-friendly control system � high rod quality and high grade of repeatability of the quality � flexible machines � on-site technical assistance for training, commissioning and start-up Seventy years; it is a very big number also to be written and, in fact, we have walked a long way and… the journey is continuing!� Carmelo Maria Brocato Vice President of the Board Commercial Director 2016 Highlights
