Introduction of Kraft paper cover aluminum winding wire
Kraft paper cover aluminum winding wire is annealed wire made of an electrician round aluminum rod extruded or drawn by a certain specification die, and then wrapped two or more layers of insulating paper (including telephone paper, cable paper, high-voltage Cable paper, turn-to-turn insulation paper, etc.) are suitable for winding wires of oil-immersed transformer coils and other similar electrical appliances. Electrician bare aluminum wire produced by extrusion process is the most ideal material for producing cable paper-covered wire.
