Transformers use wound conductors to transfer electrical energy between circuits and adjust voltage levels. Magnet wire and specialty conductors help form the windings that enable efficient power conversion in distribution, industrial, commercial, utility, and energy infrastructure applications.

Because transformers are expected to operate reliably for long service lives, winding materials must support insulation integrity, thermal performance, and electrical efficiency. Essex Solutions provides conductor solutions engineered to help manufacturers build transformers that support dependable power delivery.
