Amorphous Metal Transformer
Amorphous core type distribution transformer Amorphous transformer manufacturers in India and other countries make these transformers by applying a special method to create the core. In conventional transformers, the core is made up of metals. Metals get heated during the magnetization and demagnetization processes. As a result, a portion of the electric energy is wasted as heat energy. An amorphous metal core transformer has the core made up of some alloys. Amorphous transformer core materials are mixed together in the molten stage and then are supercooled. The process is very similar to making glasses. So, the amorphous transformer manufacturers call the amorphous metal distribution transformer as the Metallic Glass Transformer as well. When the metals used for the core are crystalline, they produce more heat. With the specially made amorphous alloy distribution transformer, the core is not crystalline. This means the transformer produces less heat during load. When the loss is super low, this type of transformer is called a super low loss amorphous transformer.
Amorphous core energy-efficient transformer The applications and advantages of an amorphous distribution transformer are ample. The amorphous iron transformer core has high magnetic susceptibility and high electrical resistance. Amorphous transformers in India are either imported or manufactured locally by amorphous core transformer manufacturers in India. These are made with a ferromagnetic amorphous metal as the core. The mixture of iron, silicon, and boron gives the core very low coercivity. The two kinds of losses are heavily reduced with an amorphous core transformer. When there is no load, the loss is called the no-load loss. This is mainly due to the core of the transformer heating up. With the non-crystalline metal alloys, the loss is reduced to more than 70%. The other type of loss is called the copper loss; this is when the transformer is under heavy load. A typical amorphous core transformer (AMT) has less copper than the conventional transformers. Due to this fact, an AMT can have less efficiency at full load. To compensate this, more copper and core materials are added to making energy-efficient AMTs. This is why they are expensive than the traditional ones. The bigger the size of the transformer, the more the copper windings are needed. These are used mainly in the grid distribution systems. There are some specialized electric motors that operate under high frequencies which would use these transformers as well. Rajasthan Powergen Transformer P. Ltd. is one of the leading amorphous core transformer manufacturers in India.
What Is Amorphous Transformer ? The cores of routine transformers comprise of stacks of laminations that are made from silicon steel with a nearly uniform crystalline structure (CRGO). In transformers with amorphous cores, a ribbon of steel is wound to make the core. Amorphous metals are made of alloys that have no nuclear arrange. They are made by the rapid cooling of liquid metals that anticipates crystallization and leaves a vitrified structure within the frame of thin strips. Due to the need for orderly structure, this sort of metal has to been given the title “The Metallic Glasses”.Rajasthan Powergen Transformer P. Ltd. has set up state of the art amorphous metal core transformer fabricating facility by bringing in the most recent amorphous metal cores manufacturing equipment.

Amorphous Core Transformer Advantages Ease in repair: It doesn’t have any complex mechanism, thus, it facilitates ease and rapid repair. Moreover, due to modular design also it helps in easy repair. Less no-load losses: In AMT’s the no-load losses are probably 20-30% less when compared with traditional silicon sheet transformers, where no-load losses repeatedly occur for a lifetime regardless of a load of the transformer. Improved overload capacity: The another key merit is that it produces less heat because the no-load loss is also less, this results in sustaining overload capacity in a better way. Consequently, it results in longer product life shell. Better distribution efficiency: Since no-load loss is quite less, it promotes higher distribution efficiency. In addition to it, this will also save your monetary investments in maintenance breakdown. Environmental caretaker: It can be said as eco-friendly to some extent as it emits lower carbon dioxide and sulphate dioxide, therefore, protecting the environment from such harmful gases. Sustaining short circuits: The amorphous metal transformers have a higher strength of sustaining short circuits due to its windings and usage of foils.

Amorphous Transformer Core Materials Amorphous transformers can be utilized inside as well outside which is the major advantage of these kinds of transformers and accurately the reason so numerous individuals are picking for these kinds of transformers. The frequency of this sort of transformer is usually 50 Hz and 60 Hz and the vector bunch that’s utilized is Dyn5 / Dyn11 or any other in case that’s the necessity and require of the client. The winding material that’s utilized is either copper or aluminum and the taping extend is off the circuit. Impedance is given in line with the appropriate standards as our Transformers could be a solid name within the advertise of transformers.
Amorphous Transformer Features The LV windings with 200~6300KVA capacity adopt cylinder or screw structure, have high mechanical strength, uniformly-distributed ampere-turns and good anti-short circuit ability All HV windings adopt multi-layer cylinder structure to improve impulse distribution of winding Low running noise and higher reliability by using three-phase three-column amorphous core, adopting our invention patent technology ofV2.0 amorphous transformers Its surface is sprayed with back and top coat after de-oiling, de-rust, and phosphatization to meet special requirements in humid and contaminate regions. It has characteristic of beautiful appearance,small volume and occupation for installation, is ideal product with good quality and free maintenance. The transformer installed locating parts to avoid displacement in transportation, meantime allnuts are fastened to assure no loose in operation
Amorphous Metal Casting Process Amorphous core material is provided within the shape of strips on reels in a five-ply organize with a thickness of 0,115 to 0,125 mm. Ribbons come completely different widths, e.g. 142 mm, 170 mm and 213 mm. The primary organize consists of forming the five-ply lace into layers of ribbon. The ribbons are bolstered to a cutting machine which combines three spools into a cover of 15 layers of ribbon, with a thickness of around 0,375 mm. The stacking calculate of 0,85 comes about in laminations that are marginally thicker.
The core is assembled by binding the layers together over an uncommon mandrel. The stacked laminations are laced over a rectangular mandrel which shapes the inner core measurements. The core is at that point gradually built (“laced”) layer by layer to make a rectangular shape that is nearly comparable to wound core making with customary steel. Typically done by hand. An inward U-shaped bracket or mandrel of CRGO makes a difference to hold the shape of the center. The exterior sheet of the core is ensured by a CRGO strip of the exact width of the undefined core ribbon. This can be fundamentally done to bolster the flexible amorphous ribbon core structure.
