The cable paper-covered wire is a wire that is extruded or drawn by an oxygen-free copper rod or an electrical round aluminum rod after being annealed by a specified die, and then wrapped with two or more layers of insulating paper on the copper (aluminum) conductor (including Winding wire for telephone paper, cable paper, high-voltage cable paper, inter-turn insulating paper, etc.), suitable for oil-immersed transformer coils and other similar electrical appliance winding wires. The electrical bare copper (aluminum) wire produced by the extrusion process is an ideal material for the production of cable paper-covered wires.
