Nylon Cable Glands

After the cable is laid, to form a continuous circuit, the lines at each end should be connected as a whole, and each connection point is the cable joint. For cable joints, it is necessary to test the insulation status of the cable joints. Once problems are found, they must be adjusted in time. So what is the reason for the failure of nylon cable glands insulation? Let's take a look.



This is the content:

  • Long-term use of insulating layer will cause aging

  • The temperature in the local area of the cable is too high

  • Problem with making cable joints






Long-term use of insulating layer will cause aging

In the long-term application of nylon cable glands, the insulating layer will be damaged by external factors, resulting in its performance decline. Among them, the common influencing factors are the insulation layer is damp, the environment and temperature change, chemical corrosion, long-term overload, etc., which lead to the aging of the insulation layer, affect the performance of the cable, and make the cable unable to meet the application requirements.


The temperature in the local area of   the cable is too high

During the long-term application of Cable Glands, there will be heat generation during operation, and the uneven air gap of the insulating layer will also cause the local temperature to be too high, which will lead to cable accidents and damage to the cables. Cable Glands are exposed to special environments, long-term overload operation, and poor overall heat dissipation, which will cause the local temperature of the cable to be too high, which will adversely affect the performance of the cable and shorten its service life.



Problem with making cable joints

The production of nylon cable glands is an operation with high technical requirements. The production of Cable Glands should meet the requirements of high precision and should be produced in full accordance with the specifications. However, from the actual situation, a small number of factories often use rough methods to manufacture cable joints for the sake of profit and catching up with the construction period during the actual production period, which will lead to uneven insulation of the cable itself, resulting in poor sealing of the cable joint accessories. In addition, due to the poor external environment, the cable joints will be exposed to the air for a long time, and moisture will penetrate the cable joints, making the cable joints damp and destroying the Cable Glands. When manufacturing cable joints, if there is not enough pipe length reserved, it will cause the problem of shrinkage of the cable insulation head, resulting in a gap at the junction of the joint and the insulation pipe. After the power is turned on, a tiny current will be continuously released from the gap, which will eventually cause the cable joint to be broken down and the cable to be damaged. This will adversely affect the Cable Glands application and fail to meet application needs
