It is a necessary basic product in the future electrification and information society. At present, the wires used in household appliances generally only have conductors and insulating layers. The insulating layers are melted and then combined with the conductors, and then formed by cooling. After repeated use, the insulating layer is easy to harden and detach, so that the conductor loses the protection of the insulating layer, causing unsafe factors such as leakage. The replacement and maintenance of the wire increase the corresponding cost, causing great inconvenience to life and production. The tensile strength is also low, so further improvement is needed.
