Paper Covered Aluminium Wire is a wire which is annealed or drawn by an oxygen-free copper rod or an electric round aluminum rod through a mold of a certain specification, and then wrapped on a copper (aluminum) conductor to wrap two or more layers of insulating paper (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 windings. The bare copper (aluminum) wire produced by the extrusion process is the most ideal material for producing cable paper covered wires.
