Paper covered wire description
Paper-covered wire is a wire that is annealed after an oxygen-free copper rod or electrical round aluminum rod is extruded or drawn through a certain specification mold, and then two or more layers of insulating paper (including Telephone paper, cable paper, high-voltage cable paper, interturn insulation paper, etc.) are suitable for oil-immersed transformer coils and other similar electrical appliance winding wires.
