[0002] Cable is a combination of wires used to transmit electrical energy, signals or data. It is widely used in power, communication, construction or industry. It is usually composed of conductors, insulation layers, sheaths and shielding layers. Different materials and structures are used to meet various environmental and functional requirements. The conductors are mostly copper or aluminum, which have good conductivity; the insulation layer and sheath are made of materials such as PVC or PE to provide electrical insulation and mechanical protection. Cables are divided into power cables, control cables and communication cables to adapt to different working conditions and requirements. Cables are an indispensable and important component in modern infrastructure.
