●Product Name: Cable paper covered wire
●Product introduction: The cable paper covered wire is an electric wire which is extruded or drawn by an electric round copper rod or an electric round aluminum rod through a certain specification of a mold, and then wrapped on a copper (aluminum) conductor to wrap two or two layers. The winding wires of the above insulating paper (including cable paper, high-density insulating paper, inter-turn insulating paper, etc.) are 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.
●Executive standard: GB/T7673-2008
