Methods of prolonging the service life of cables

Generally speaking, the service life of wires and cables is not less than 20 years, but external factors often affect the length of their service life, such as insulation layer damage, aging, corrosion, etc. In the actual use process, the reason for cable aging is In all respects, how to prolong the service life of cables?

The length of the service life of the wire depends on the quality of the wire and the environment in which the wire is installed and used. The wire mainly relies on the outer layer of insulation. After a long time, it is corroded by corrosive gas, and the insulation performance gradually decreases. It gradually ages and hardens, becomes brittle or falls off. At this time, it can not function as insulation. The insulating layer on the exterior of household wires is mostly made of plastic and rubber, which will age and lose its insulating effect after a long time of use. It is very dangerous for the wire to lose the insulation performance. If the two wires touch together or the live wire touches something connected to the ground, the phenomenon of running electricity will occur, which will increase the temperature of the local wire, generate sparks, and cause accidents.

Therefore, we can pay attention to the following points in the process of use, which can also effectively extend the service life of the cable:

1. Avoid man-made damage

The wires laid directly on the outer wall must be careful not to be damaged artificially. The wires are mainly insulated by the outer insulating layer. When the wires age and become hard, brittle or fall off, the surface insulation performance will be reduced.

Second, pay attention to moisture

Wires and cables should pay attention to moisture-proof. In wet conditions, short-circuit leakage is more likely to occur when moisture is immersed into the metal conductor. In addition to affecting the service life of the wire, it is also prone to accidents.

3. Prevent sun aging

There are many LAN cables under the eaves. At this time, be careful not to expose to the sun and the ambient temperature should not be too high. Because ultraviolet radiation will accelerate the aging of the cable, thereby shortening the service life.

Fourth, pay attention to storage

When storing the wires, it is strictly forbidden to contact with acids, alkalis and mineral oils, and they should be stored separately from these corrosive substances. Avoid storing cables in the open air as much as possible.

Five, regular inspection

In normal use, it is necessary to regularly check the use of the electrical and wiring in the home, and carry out maintenance, repair and replacement in a timely manner.
