AT ISSUE There is a common misconception that a distribution transformer with copper windings is in some way more efficient, more reliable, or has higher short circuit strength when compared to a transformer with aluminum windings.
Improvements in technology regarding the use of aluminum in transformers have made aluminum-wound transformers the ideal choice for today's applications.
Operating Cost - Cooper Power Systems designs aluminum-wound transformers with windings of a larger cross-sectional area than would be used for a copper wound unit. This larger cross-sectional area translates to a lower current density, and an equivalent operating temperature. By reducing the current density in the windings, a low-loss design can be achieved with aluminum or copper windings.
Reliability - A transformer's life is defined by the life of its insulation system. Because Cooper aluminum-wound and copper-wound units run at equivalent operating temperatures, the insulation systems age at the same rate for each design. Lower Cost First - Whether low losses are the goal or not, aluminum windings are less expensive than copper windings. The following example shows two equivalent-loss designs, on with aluminum windings and one with copper windings.
Appearance standard:Soft surface, no grease, smooth and without feeling scratch. Tolerances of side burr, thickness and width should less than that in the standard.
Packing: Standard Export Wooden Pallet or Case. Also we can meet special requirements of customers. Deliver in coil, hard paper core inside, with paper interleaved. Eye to wall and Eye to Sky, both ok.
Applications: Excellent formability, weldability and corrosion resistance. Mainly used for electric material in high and low pressure winding for dry type transformer and oil transformer.
