Grade1 180 UL Certificated UEW Enamelled Copper Wire Insulated Solid IEC/JIS/NEMA
A transformer is a device that transfers electrical energy from one circuit to another through its coils (windings). The properties needed for motor windings are similar to those needed for transformers, but with the additional requirement to withstand mechanical vibration and centrifugal forces at operating temperatures.
