Introduction: The cable paper-covered wire includes cable paper covered aluminum wires and cable paper covered copper wires. They are made of oxygen-free copper rods or electrical round aluminum rods that are annealed after being extruded or drawn by a specification die, and then wrapped two or more layers on the copper (aluminum) conductor Insulating paper (including telephone paper, cable paper, high-voltage cable paper, turn-to-turn insulation paper, etc.) winding wire, suitable for oil-immersed transformer coils and other similar electrical winding wires. The bare copper (aluminum) conductors produced by the extrusion process are ideal materials for the production of cable paper covered wires.
