[0002] Cable is an electrical energy or signal transmission device, usually composed of several or several groups of wires. Cables have different definitions. Definition 1: A wire made of one or more mutually insulated conductors and an outer insulating protective layer to transmit electricity or information from one place to another. Definition 2: A rope-like cable usually made of several or several groups of wires (at least two in each group) twisted together. 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. The cable has the characteristics of internal power and external insulation. Cables can be classified into power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. They are all composed of single or multiple strands of wires and an insulating layer, used to The manufacturing of wires and cables for connecting circuits, electrical appliances, etc. is completely different from the production method of most electromechanical products.
