In daily life and production will use a variety of electrical equipment, these electrical equipment according to a certain design layout, through wires, wires and other connections, in the circuit will inevitably use cable connectors or electrical connectors. In general, PG Cable Gland must be strictly inspected before they leave the factory and tested before they are put into operation. Additional cable connectors that are purchased or completed from the outside require routine inspection because they are usually weak links in the electrical circuit. The following situations are not caused by the failure of the cable connector and the use of unqualified cable connectors.

1. Repeated construction can be seen everywhere now, but some construction units did not take the relevant engineering drawings (drawings) before the construction, it will make the construction of the cable, not installed after the construction of cable connectors.

2. When laying indoor lighting, air conditioning installation and other lines, in order to save costs, when the length of wire and cable is not enough, wiring at will, only electrical steel tape winding connection without PG Cable Gland.

3. Electrical workers do not pay attention to safety and quality. They do not install junction box where the electrical junction box needs to be laid. They do not install sleeve where the flexible metal wire protection sleeve is used. They install hook connection in the place where the Plastic Cable Gland is needed, but do not use cable connector. In this way, the resistance of the contact surface will be increased, and the insulation layer such as insulation tape will be accelerated by heating continuously when the power is on. If the contact parts are loose, it will cause fire or electric arc, which will easily cause fires.

4. There is only focus on early investment, ignoring the later maintenance costs.

Through the above introduction, I believe that we have a certain understanding of the importance of correct installation of Plastic Cable Gland, then we need to consider the application and selection of cable joints before construction. Especially in the construction should pay attention to the installation and connection of cable and wire joints, daily use after construction also needs to strengthen the inspection and investigation, so as to avoid the occurrence of faults and accidents.

All kinds of joint parts are used in the pipe fittings industry. With the wider use, the causes of the faults are also different. Therefore, the related information of cable joint fault analysis is also concerned by everyone.

The failure of Plastic Cable Gland is caused in part by long wear and tear, but also due to improper operation of the joint device caused by damage. When a fault or short circuit occurs, the staff concerned need to analyze the surface and inside of the cable connector, and then find the appropriate method to make the cable connector work properly.

First of all, it is necessary to analyze the faults on the surface of the joint, and then find the appropriate way to deal with them, so as not to affect the use of the internal cable because of the faults in the joint part.

Secondly, it is necessary to analyze the faults in the cable connector. After eliminating the non-surface faults, the analysis of the internal faults can help us to better formulate the relevant solutions to the faults.

Although different connector products have been widely used at this stage, operators need to understand the working principle, basic characteristics and performance advantages of PG Cable Gland, so that they can analyze the faults of such components at the first time when they have fault problems or short-circuit phenomena, so as to solve the problems. Plan.

In addition to the above fault analysis, regular cleaning and maintenance of the cable connector, in order to make the connector device to maintain the best state, and will effectively extend its service life, reduce the probability of failure.
