Enameled Copper Wire

Introduction of enamelled Copper wire:
Enameled copper wire is made of copper rod, which are draw by the specification mould,it is the baked winding wire with multiple-layers of insulating paint after annealing softening treatment. 
Zhengzhou LP Industry enameled copper wire is based on the national standard GB, the US NEMA standard and the EU IEC60317 standard or the technical requirements of customers to formulate production standards. The main performance control indicators are conductor size, conductor fillet size, insulation thickness, overall size, elongation, Spring back, flexibility and adhesion, room temperature (high temperature) breakdown voltage, thermal shock and other items.
