Cable accessories are products that connect cables to power transmission and distribution lines and related power distribution equipment. They generally refer to the intermediate and terminal connections of various cables in a cable line, forming the power transmission network together with the cables. Cable accessories are primarily designed based on the characteristics of the cable structure, restoring cable performance while ensuring cable length extension and proper termination connections.
The reliability of high-voltage cable accessories can be evaluated from aspects such as electrical performance, sealing and moisture-proof performance, mechanical performance, and technological performance.
