Polyimide enameled copper (aluminum)round wire class220

Enameled copper (aluminum) round wire is a wire using an oxygen-free copper rod or electrical round aluminum rod under extrusion by requested specification mold or dawning and annealing procedure, Then painted with required temperature tolerance level insulating coatings by mold type or blanket type, after baking procedure, the conductor and insulating coating will become an integral productThe product is now widely used in oil-immersed transformers, dry transformers, electric reactor, motor, choke coils, air compressor and other similar electrical instruments.
