[0002] Wires and cables are wire products used to transmit electrical energy, information and realize electromagnetic energy conversion. Wires and cables in a broad sense are also referred to as cables, and cables in a narrow sense refer to insulated cables. Wires and cables often need to be cut during the production and processing process. Wires and cables are cut into different lengths to meet different usage requirements.
