Description

technical field [0001] The invention relates to a power cable sheathing material, which belongs to the field of electric wires and cables. Background technique [0002] Power cables are cables used to transmit and distribute electric energy. Power cables are often used in urban underground power grids, outgoing lines of power stations, internal power supply of industrial and mining enterprises, and underwater transmission lines across rivers and seas. In power lines, the proportion of cables is gradually increasing. Power cables are cable products used to transmit and distribute high-power electric energy in the main line of the power system, including 1-500KV and above various voltage levels and various insulated power cables. [0003] There are various requirements for power cable indicators, such as insulation, tensile strength, operating temperature, flame retardant performance and other indicators. Continuously improving the performance of sheath materials is an urgent...
