1.Introduction:This product is premium copper or aluminum conductor, evenly wrapped with polyimide film or polyimide, fluorine 4.6 composite film. Fluorine 4.6 can be melt and make a whole with the film and conductor after heated. It has strong voltage resistance, thin thickness and thermal class up to 220℃. The product is widely applied in electric machines,reactors,electric welding machines and similar electrical instruments. The electrical bare copper or aluminum wire with extrusion process is the ideal material for polyimide film wrapped copper or aluminum wire.
