[0002] A cable is usually a rope-like structure formed by stranding several or several groups of wires. The wires in each group are insulated from each other and are often twisted around a center. The whole is wrapped with a highly insulated covering layer. Cables include power cables, control cables, compensating cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, and aluminum alloy cables, etc. They are all composed of single-strand or multi-strand wires and insulating layers, and are used to connect circuits and electrical appliances, etc.
