Cables have been widely used nowadays, but there are requirements for cables in the process of transportation, installation and storage, because many factors will cause cable damage and reduce the service life of cables
Cable moisture is a very common problem
Cable moisture or water will reduce the insulation resistance of cables and cause problems I
what are the causes of cable moisture 1
After the cable has been used for a period of time, the remaining cables are directly placed in the open air and have not been sealed
If the environment is wet, water vapor may enter the cable 2
If the plastic packaging is not tight, damaged or notched, most of these cables are affected by water vapor 3
Improper operation of the staff makes the cable head enter water vapor 4
The insulation of the cable is seriously damaged, causing water to enter the cable 5
The cables stored in the warehouse for a long time and the cables next to the ground may be affected by the moisture on the ground 2
Once the cable is found to be in water, how to deal with it Relying on the existing technical means, it is difficult to remedy the water entering the cable
Therefore, in real life, if the cable is found to be in water, the common method is to saw off the cable several meters in front of the cable, and then check whether it is dry
If there is still water, it needs to be sawed again until it is completely dry
If the whole cable is in water, it will basically announce the end of the cable Therefore, it can be seen that once the cable enters the water, it can hardly be saved in the existing technology
Therefore, for the problem of cable moisture and water, the importance of prevention is greater than repair III
how to prevent cable from moisture and water 1
Thicken the insulating layer to prevent damage and water inflow 2
Choose a better insulating material
Impurities and pores in the insulation will cause water vapor to enter 3
Ensure that the cable head is well sealed 4
Strengthen the technical literacy of the staff to avoid water inflow caused by mistakes during installation 5
Store the remaining cables in a dry closed warehouse to avoid direct contact with the ground
