                                 Cable Joint Classification

1. It can be divided into indoor and outdoor types according to the installation location.

2. It can be further divided into hot-shrink (the most commonly used), dry-pack, epoxy resin casting, and cold-shrink based on the materials used for production and installation.

3. By the material of the wire core, they can be classified into copper-core power cable heads and aluminum-core power cable heads.

4. Cable joints are classified by material into plastic cable joints and metal cable joints. Metal cable joints are further divided into multi-hole metal cable waterproof joints, anti-bending metal cable joints, double-locking metal cable waterproof joints, plastic hose cable joints, and metal hose cable joints, etc.

 The role of cable joints is to connect two or more cables together to form a continuous electrical circuit. They provide a secure and reliable connection, preventing electrical short circuits and ensuring the smooth flow of electricity.

Its main function is to ensure the smooth operation of the lines, maintain the sealing of the cables, and ensure the insulation grade at the cable joints, making it operate safely and reliably. If the sealing is poor, not only will oil leakage cause the oil-impregnated paper to dry up, but moisture will also penetrate into the cable's interior, reducing the insulation performance of the paper.

Some electrical installation workers often ignore the installation when laying wires.Plastic cable waterproof connectorsQuality: When it should be used.Insulation SleeveNot installed with a casing; should useWiring BoxThere is no wiring box installed in these areas; even at the junction of electrical wires, the method of connection is not twisted, but an illegal hook-like method. This hook-like method has a large contact resistance, which causes continuous heating when the wires are electrically connected. This can lead to the drying and carbonization of the nearby wood, eventually leading to combustion and the potential for a fire.

Electric wire joints that heat up not only cause significant energy losses but also seriously affect the normal operation of electrical equipment. In mild cases, the working current in the circuit increases, leading to a shortened life of the electrical equipment. In severe cases, it can suddenly interrupt production, scientific research, medical operations, and other activities, leading to unforeseen losses. It can also cause fires, electric shocks, and other accidents, resulting in unquantifiable losses.
