Description

technical field [0001] The invention relates to the technical field of power transmission and transformation line protection, in particular to an insulating layer for power transmission and transformation lines. Background technique [0002] Power transmission and transformation is the transmission of power from the power plant to the grid. It increases the low voltage (such as 500,000 volts) for remote transmission. The higher the voltage of the same power, the smaller the current, and the smaller the current, the smaller the loss on the line. Generally, in the power industry, 35kV ~ 1000kV is called power transmission and transformation. The power cable for power transmission and transformation is composed of single-strand or multi-strand wires and insulating layers, and is used to connect circuits and electrical appliances. The breakdown strength of traditional cables is not very high due to inappropriate material matching. In the actual use process, there are atmospheric...
