[0002] The cable intermediate joint is the cable joint in the middle of the cable line. The intermediate joint is a cable accessory used for the intermediate connection of cross-linked cables or oil-immersed cables of various voltage levels. Its main function is to make the line unobstructed, keep the cable sealed, and ensure the insulation level at the cable joint so that it can operate safely and reliably. The cable intermediate joint connects the two ends of the cable in the power system, which can effectively maintain the continuity of the power system and ensure the normal transmission of power signals. If the cable intermediate joint fails or has a poor connection, it will cause the interruption of the power signal, which will directly affect the operation and normal work of the power system. The cable intermediate joint increases the service life of the cable line. As a component of the cable line, the cable intermediate joint can effectively prevent water, moisture, high temperature, and corrosion, thereby effectively extending the life of the cable line.
