Background

Cables are generally rope-like cables made by stranding several or groups of conductors (at least two in each group), each group being insulated from each other and often twisted around a center, the entire outer surface being coated with a highly insulating coating. The cable has the characteristics of internal electrification and external insulation, and the cable can be a power cable, a control cable, a compensation cable, a shielding cable, a high-temperature cable, a computer cable, a signal cable, a coaxial cable, a fire-resistant cable, a marine cable, a mining cable, an aluminum alloy cable and the like. They are composed of single or multi-strand wires and insulating layers, and are used for connecting circuits, electric appliances and the like.

(1) The traditional cables can meet various complex environments in the laying and erecting process, some cables are in humid areas and have high annual moisture and humidity, some cables are erected outside the open air, the cables can be corroded to a certain degree under different environments and illumination intensities in different areas, and the strength and toughness of the cables are tested in the laying process;

(2) the insulating parcel mode of ordinary outsourcing that traditional cable adopted, because long-time the erosion that receives the environment, the insulating layer of cable outsourcing receives the damage, just so makes the cable not have insulating function, plays the influence to the transmission of cable on the one hand, and on the other hand also has the risk of electric leakage.
