[0002] A cable is usually a rope-like electrical energy or signal transmission device composed of several or several groups of wires (at least two in each group). Each group of wires is insulated from each other and often twisted around a central wire. The entire outer layer is covered with a highly insulating covering. The cable has the characteristics of internal power conduction and external insulation.

[0003] Coating is a process method that uses continuous coating machines, continuous extruders, etc. to add different materials to the outside of the conductor according to the different performance requirements of wires and cables. The coating process content is diverse, and the coating process for different materials is different. For example, rubber, lead, aluminum, plastic and other materials mostly use extrusion process; polyester film, aluminum-plastic composite film and other strip materials mostly use longitudinal wrapping process; mica tape, non-woven fabric, alkali-free glass and other fiber materials mostly use winding process; asphalt, insulating paint and other materials mostly use dipping process.
