Cable Joint Kits introduction and matters needing attention

After the cable is laid, to make it a continuous line, each segment of the line must be connected as a whole, and these connection points are called Cable Joint Kits. Cable Joint Kits are used to lock and fix the incoming and outgoing cables and play the role of waterproof, dustproof, and anti-vibration. Many friends may be relatively new to Cable Joint Kits. Let's take a look at the introduction and precautions of Cable Joint Kits in detail. Here are some answers.

Classification of Cable Joint Kits.

First, according to the installation location, it can be divided into indoor and outdoor Cable Joint Kits. Second, according to the production and installation materials, it can be divided into heat shrinkable type (the most commonly used one), dry pack type, epoxy resin casting type, and cold shrinkable type. Third, according to the core material, it can be divided into copper core power Cable Joint Kits and aluminum core power Cable Joint Kits. Fourth, according to the joint material, it is divided into plastic Cable Joint Kits and metal cable joints. Metal Cable Joint Kits are further divided into porous metal cable waterproof joint kits, anti-bending metal Cable Joint Kits, double-lock metal cable waterproof joint kits, plastic hose Cable Joint Kits, metal hose Cable Joint Kits, etc.

The role of Cable Joint Kits.

The main function of Cable Joint Kits is to make the circuit unobstructed, keep the cable sealed, and ensure the insulation level at the cable joint so that it can operate safely and reliably. If the seal is not good, not only will the oil leak and cause the oil-impregnated paper to dry but also moisture will invade the inside of the cable and reduce its insulation performance. Cable Joint Kits are tools used to connect two wires to make the wires safe, unobstructed, sealed, and safe and reliable.

Causes of heating in Cable Joint Kits.

Some electrical installation workers often do not pay attention to the installation quality when laying wires. For example, no casing should be installed where insulating sleeves should be used; junction boxes should not be installed where junction boxes should be used; even at the wire joints, instead of splicing, an illegal hook-like connection method is used. The contact resistance of this hook-like connection is very high, and continuous heating when energized will gradually dry and carbonize the nearby wooden boards. Finally, it burns and causes a fire. The heating of Cable Joint Kits will not only cause a large amount of power loss, but also Cable Joint Kits will seriously affect the normal operation of electrical equipment. The working current in the line increases, the life of electrical equipment is shortened, and the production, scientific research, medical operation, and other activities in progress will be suddenly interrupted, and fire and electric shock accidents will be caused, causing immeasurable losses.

Causes of heating in Cable Joint Kits.

Where the cable body has an inner shielding layer, the inner shielding layer of the joint of the conductor part of the crimping tube must be restored when making Cable Joint Kits. A part of the internal semiconductor shield of the cable should be set aside so that the internal shield of the Cable Joint Kits on the connecting tube can be connected to ensure that the internal and external semiconductor shields are semiconductor materials and play a unified role. The electric field outside the insulation of the cable and the Cable Joint Kits. Like the internal semiconductor shield, it plays a very important role in cables and Cable Joint Kits. The external semiconductor ports must be neat and uniform, and a smooth transition with the insulation is required, and the Cable Joint Kits are added with the semiconductor tape to be connected with the semiconductor shield outside the cable body.
