Description

Technical Field

[0002] Cable joints are also called cable heads. After the cable is laid, in order to make it a continuous line, each section of the 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 joints at both ends of the line are called terminal heads. Cable joints are used to lock and fix the incoming and outgoing lines, and play a role in waterproofing, dustproofing and vibration prevention. The main function of the cable joint 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 joint is a very important component in the power system, responsible for connecting different cable segments and transmitting electricity from the power plant to the user's electrical equipment. However, due to various reasons, such as vibration, friction, humidity and other factors, the cable joint bayonet may have problems such as loose joints and cracks during use, affecting the safe and stable operation of the power system.
