Cable joint for power engineering
Technical Field
The invention relates to the field of power engineering, in particular to a cable joint for power engineering.
Background
The cable connector is also called a cable head. After the cable is laid, in order to form a continuous line, all the sections of the cable must be connected into a whole, the connection points are called cable joints, the cable joint in the middle of the cable line is called an intermediate joint, the cable joints at two ends of the line are called terminals, and the cable joints are used for locking and fixing incoming and outgoing lines and play a role in preventing water, dust and vibration.
At present, when a power cable is connected, the outer insulating layers of two cable ends to be connected are usually removed by using wire stripping pliers, so that core wires are fully exposed, then the two core wires are twisted together forcibly, finally, an insulating adhesive tape is used for winding a connecting part, the connecting part is wound by a connecting wire, the connection is unstable, the sealing performance is poor, and the joint of a common cable is easy to wear, damage or destroy the cable.
