Background Art

A cable is a device for transmitting electric energy or signals, usually composed of several or several groups of wires. Definition 1: It is a wire made of one or more mutually insulated conductors and an outer insulating protective layer, which transmits electricity or information from one place to another. Definition 2: It is usually a rope-like cable made 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 center. The entire outside is covered with a highly insulating covering layer. The cable has the characteristics of internal power conduction and external insulation.

The existing cables currently have poor anti-pulling performance, which causes the cables to be easily broken and damaged due to the strong mechanical pulling force when they are pulled during laying, shortening the service life of the cables.
