The main function is to make the line unobstructed, keep the cable sealed, and ensure the insulation level at the cable joint to make it run safely and reliably. If there is no seal or the seal is not good, not only will the oil leak and the oil invade the paper, but the gas will also invade the inside of the cable, causing its insulation performance to drop.

Cable connectors are also called cable ends. After the cable is laid, in order to make it a continuous line, each line must be connected as a whole. These connection points are called cable joints. The cable joint in the middle of the cable line is called the intermediate joint, and the cable joint
