Typically rope-like cables formed by twisting several or groups of conductors (at least two in each group), each group being insulated from each other and often twisted around a centre, the whole being covered with a highly insulating coating. The cable has an inner energized, outer insulated feature. The cables include power cables, control cables, compensation cables, shield cables, high temperature cables, computer cables, signal cables, coaxial cables, fire resistant cables, marine cables, mining cables, aluminum alloy cables, and the like. They are composed of single or multi-strand wires and insulating layers for connecting circuits, appliances, etc.
The cable joint is also called a cable head. After the cable is laid, the sections must be connected as a unit in order to form a continuous line, and these points of connection are called cable joints. The cable joints in the middle of the cable line are called intermediate joints, while the cable joints at both ends of the line are called terminal heads. The cable connector is used for locking and fixing the incoming and outgoing lines, and plays a role in preventing water, dust and vibration. Its main function is to make the line unobstructed, make the cable keep sealing, and guarantee the insulating grade of cable joint department, make it safe and reliable to operate. If the sealing is poor, not only the oil-immersed paper will be dried up due to oil leakage, but also moisture will invade the cable, and the insulation performance of the paper will be reduced. The connector is divided into a plastic cable connector and a metal cable connector according to the connector materials. The metal cable joint is divided into a porous metal cable waterproof joint, a bending-proof metal cable joint, a double-locking metal cable waterproof joint, a plastic hose cable joint, a metal hose cable joint and the like.
