What are the causes of the aging of wires and cables? (1)

      The most direct cause of aging failure of wires and cables is the breakdown of insulation. There are many factors to reduce the conductive insulation. According to the actual operation experience, it can be summed up as follows.

1. Cable gland failure. The cable gland is the weakest link in the cable line, and the cable gland failure caused by the direct negligence of personnel (poor construction) often occurs. In the process of making cable glands, if there are some original nets such as loose crimping and insufficient heating, the insulation of cable head will be reduced, which will lead to accidents.
