  • Do you have questions about transformers? Our FAQ page has ...

    The type of winding material does not affect the transformer's reliability. A transformer's life is defined by the life of its insulation system. Because aluminum-wound and copper-wound units run at equivalent operating temperatures, the insulation systems age at the same rate for each design. An advantage of aluminum windings is weight.
