Background

Cable is a generic term for optical cables, electrical cables, and the like. The cable has many purposes, is mainly used for controlling installation, connecting equipment, transmitting power and other multiple functions, and is a common and indispensable object in daily life. The cable is electrified, so that the installation needs to be particularly cautious, and the common copper and aluminum rods for the electric wires and cables pass through one or more die holes of a drawing die by a wire drawing machine at normal temperature, so that the section of the electric wires and cables is reduced, the length of the electric wires and cables is increased, and the strength of the electric wires and cables is improved. Drawing is the first procedure of each wire and cable company, and the main process parameter of drawing is the die matching technology.

The existing cable is simple in structure and single in layer number, flame retardant performance of the cable is not high, the cable cannot be effectively protected when a fire disaster occurs, the cable is often bent in use, and the bent part is in a tightening state and easily cracks, so that the service life of the cable is shortened.
