Background

Cables are generally rope-like cables made by stranding several or groups of conductors (at least two in each group), each group being insulated from each other and often twisted around a center, the entire outer surface being coated with a highly insulating coating. The cable has the characteristics of internal electrification and external insulation; the cable connector is also called a cable head, and after the cable is laid, in order to form a continuous line, all the sections of the cable must be connected into a whole, and the connection points are called cable connectors. The cable joints at the middle of the cable run are called intermediate joints and the cable joints at the two ends of the run are called termination joints. The cable joint is used for locking and fixing incoming and outgoing lines, plays a role in water resistance, dust resistance and vibration resistance, and has the main functions of enabling the lines to be smooth, enabling the cables to be kept sealed, ensuring the insulation grade at the cable joint and enabling the cable joint to operate safely and reliably. If the sealing is poor, not only oil leakage causes oil-impregnated paper to dry up, but also moisture invades into the cable, so that the insulating property of the cable is reduced.
