Aluminum Strip for Transformers

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. RECOMMENDATION Improvements in technology regarding the use of aluminum in transformers have made aluminum-wound transformers the ideal choice for today’s applications. RATIONALE 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
