What is the main function of cable joints, what are nylon cable joints, and what are the commonly used classifications? Many people still don’t know. Today, Nylon cable gland manufacturers will answer the above questions for you. Now let’s take a look.

The main function of nylon cable joint
The main function of the cable joint is to make the line unobstructed, keep the cable sealed, and ensure the insulation level of the cable joint so that it can run safely and reliably. If the seal is not good, not only oil leakage will cause the oil-impregnated paper to dry up, but also moisture will invade the inside of the cable, reducing the insulation performance of the paper.

The cable joint is also called the cable head. After the cable is laid, to make it a continuous line, each section of the line must be connected as a whole, and these connection points are called cable joints. The main function is to make the line unobstructed. The phenomenon of heating of the wire joints generally first manifests as a peculiar smell around the wire joints, which can be smelled. This is because the heat of the wire joints makes the outer insulation layer smell; secondly, smoke and redness are emitted from the wire joints. , The outsourcing insulation layer turns black, catches fire, or even disconnects.

What are Nylon Cable Glands?
The cable joint is a component in the cable line, which is used to realize the connection of two cables and improve the electric field at the end of the two cables. When one end of the cable is connected to other electrical equipment, a cable terminal is required; when one end of two cables is connected to a cable line, a cable intermediate joint is required, and the cable terminal and the intermediate joint are collectively referred to as a cable end. The main function of the cable head is to seal the cable. When the cable leaves the factory, both ends are sealed, but when laying or connecting, its ends must be cut open, which destroys its sealing. If the end of the cable is not sealed during laying or the quality of the cable head is unqualified, the cable head will leak oil, and finally, the insulating oil will dry up, and the insulation performance will be greatly reduced, which will affect the safe operation of the cable.

Classification of cable glands
① According to the joint material, it is divided into plastic cable joints and metal cable joints. Metal cable joints are further divided into porous metal cable waterproof joints, anti-bending metal cable joints, double-lock metal cable waterproof joints, plastic hose cable joints, metal hose cable joints, etc.
②According to the installation site, it can be divided into the indoor type and outdoor type.
③ 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.
④ According to the wire core material, it can be divided into copper core power cable head and aluminum core power cable head.

There are two types of cable terminals: indoor and outdoor. Nylon cable joint manufacturers warmly remind us that because outdoor cable terminals are easily affected by wind, rain, ice, snow, and ambient climate, the working conditions are poor and the structure is relatively complicated. The working condition of the indoor cable terminal is better, no waterproof device is required, and the cable core wire can be directly connected to the equipment.

Brass cable gland manufacturer shares the key points of cable joints in construction
In the installation of power engineering, the cable terminal head and the intermediate joint are important power equipment components in the power transmission and transformation cable line. The manufacturer of the brass cable gland tells you that its function is to disperse the electric field at the cut-off point of the outer shield of the cable terminal head. Protect the cable from being broken down, and also have the functions of internal and external insulation and waterproofing. In cable lines, more than 60% of accidents are caused by accessories, so the quality of connector accessories plays a very important role in the safety and reliability of the entire power transmission and transformation. Conductor connection requires low resistance and sufficient mechanical strength, and no sharp corners can appear at the connection. Brass cable gland manufacturer reminds you that crimping is commonly used to connect medium and low-voltage cable conductors, and attention should be paid to crimping: (1) Select a conductor connecting pipe with appropriate conductivity and mechanical strength. (2) The matching gap between the inner diameter of the crimping tube and the outer diameter of the connected core is 0.8-1.4mm. (3) The resistance value of the joint after crimping should not be greater than 1.2 times that of the equal-section conductor, and the tensile strength of the copper conductor joint should not be lower than 60N/mm2. (4) Before crimping, the outer surface of the conductor and the inner surface of the connecting pipe are coated with conductive glue, and the oxide film is destroyed with a wire brush. (5) Use a file or sandpaper to smooth the sharp corners and burrs on the connecting pipe and core conductor. Inner semiconductor shielding treatment 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 the joint. They can communicate with each other to ensure the continuity of the inner semiconductor so that the field strength at the junction is evenly distributed. Treatment of the outer semiconductor shield is a semi-conductive material that acts as a uniform electric field on the outside of the cable and connector insulation. Like the inner semiconductor shield, it plays a very important role in the cable and connector. The outer semiconductor port must be neat and uniform, and it also requires a smooth transition with the insulation, and the semiconductor tape is added to the joint to connect with the outer semiconductor shield of the cable body. Treatment of cable reaction cones During construction, the shape and size of the reaction cones are accurate and the potential distribution on the entire cone surface is equal. When making cross-linked cable reaction cones, special cutting tools are generally used, and micro-flame can also be used. Slightly heat, and cut with a sharp knife, after the basic shape, then use 2mm thick glass to repair and scrape, and finally use sandpaper to polish from coarse to fine until it is smooth. Metal shielding and grounding treatment The role of metal shielding in cables and connectors is mainly to conduct cable fault short-circuit currents and shield electromagnetic fields from electromagnetic interference to adjacent communication equipment. In operating conditions, metal shielding is at zero potential under good grounding conditions. After the cable fails, it has the ability to conduct short-circuit current in a very short time. The grounding wire should be reliably welded, the metal shield and armored tape on the cable body at both ends should be firmly welded, and the grounding of the terminal head should be reliable. Sealing and mechanical protection of joints The sealing and mechanical protection of joints are the guarantees to ensure the safe and reliable operation of joints. Manufacturers of brass cable gland suggest that water and moisture should be prevented from penetrating into the joints. In addition, joint protection grooves should be built or cement protection boxes should be installed at the joint position.
