Product Details

●Product introduction: This product is made of oxygen-free copper rod or electric round aluminum rod after being extruded or drawn by a certain size of the mold, and then 2-3 layers of polyimide film are evenly wrapped on the copper-aluminum conductor. As the winding wire of the insulation layer, the product has excellent withstand voltage performance and thin insulation thickness, heat resistance up to 220 ° C, mainly used for winding of motor, reactor, electric welder or other similar electrical products. The bare copper (aluminum) wire produced by the extrusion process is the most ideal material for producing polyimide film covered wires.
