Overview


Paper Covered Wire Cable paper covered wire is the winding wire and its condutor is made of oxygen-free copper rod or electrical round aluminum rod through a certain specifications of the extrusion mould or after drawing wire and annealing treatment, and then the copper (aluminum) conductor is wrapped on two or more than two layers of insulating paper (including telephone paper, cable paper, high voltage cable paper, turn-to-turn insulation paper), suitable for oil-immersed transformer coil and other similar electrical winding thread.
