Functions, Heating Causes And Grade Standards Of Metal Cable Waterproof Joints

Nylon Cable Gland can be seen in many industrial equipment and cables, but many people are relatively unfamiliar with it, such as: what is its function? What are the reasons for heating? What is its grade standard? Many people may not know anything about it. Today we will briefly introduce some of its knowledge points to you so that you can better understand the product.

Function of the product

The main function of the metal cable waterproof joint is to keep the circuit in a smooth state, ensure the sealing effect of the cable, enhance the insulation performance of the joint, and allow the cable to operate stably and safely. Once the cable is not sealed or the seal is not tight, the cable connectivity will decrease, and even cannot be connected smoothly.

Reason for heating

The heating of the metal cable waterproof joint is very harmful. It will not only cause a large amount of electric energy to be lost, but also affect the stable operation of electrical equipment and shorten the service life of electrical equipment. It can be said that the loss may be very large.

The main reason for the heating of the metal cable waterproof joint is that the construction personnel did not install it correctly when laying the cable line.

When the construction personnel did not use the junction box where the junction box was needed. The location where the insulating sleeve is required is not used, the method of cross-jointing and twisting at the cable joint is unreasonable, etc., which will cause the joint to heat up after installation.

Grade standard

The international grade standards for metal cable waterproof joints are mainly based on waterproof performance and anti-fixation performance. Generally, there will be an IPXX logo on the product packaging, which is its grade standard. The first digit ranges from 0 to 6. The larger the number, the higher the grade. The second digit ranges from 0 to 8. Similarly, the larger the number, the higher the grade.
