[0002] Flat cable is a flat wire formed by combining many wires together. The conductive core of flat cable adopts soft structure, good flexibility, strong toughness, and has many advantages such as heat radiation resistance, cold resistance, acid and alkali resistance, stable electrical performance, and long service life. It is widely used in power connection and control signal lighting of various mobile power devices in power, ports, metallurgy and other industries. For example, the gantry crane of hydropower station uses flat cable as mobile power cable for power supply.
