As an indispensable component in the power system, high-voltage cables undertake the important task of power transmission and distribution. With the rapid growth of my country's economy, the demand for electricity continues to rise, and the application scope of high-voltage cables is also expanding.

High-voltage cables are defined as cables with a rated voltage of 110kV or more, and their components include conductors, insulation layers, sheaths, fillers and shielding layers. According to different insulating materials, high-voltage cables can be divided into types such as cross-linked polyethylene insulated cables, polyvinyl chloride insulated cables and rubber insulated cables. From the perspective of structural form, there are many forms such as single-core cables, multi-core cables and combined cables.

First of all, the high-voltage cable has a precise structural design, and each component works together to ensure the safe and stable transmission of electricity under high-voltage conditions. The conductor, as the core of power transmission, is usually made of copper or aluminum and has the ability to withstand high voltages. The insulation layer is responsible for isolating the conductor from the external environment, effectively preventing current leakage and energy loss. The function of the shielding layer is to reduce electromagnetic interference, thereby improving the signal transmission quality of the cable. The sheath not only protects the entire cable, but also enhances its wear resistance and resistance to external environmental factors. In some high-voltage cable designs, an insulating shield is added outside the insulation layer to further improve the electrical performance of the cable.

Secondly, the characteristics of high-voltage cables are outstanding. In emergencies such as fires, flame-retardant high-voltage cables significantly improve safety. High-voltage cables are widely used in many key areas, such as nuclear power plants, subway stations, telephone exchanges and computer control centers, high-rise buildings, hotels, radio and television stations, important military facilities, and oil platforms. The selection of these application scenarios not only reflects the advantages of high-voltage cables in flame retardant performance, but also demonstrates their indispensable position in modern society.Secondly, the characteristics of high-voltage cables are outstanding.
