What to do if water enters the cable? Is there any way to solve it?
Water ingress of cables is also a very common power cable failure. How do you solve the problem of water ingress of cables? It is troublesome to have water in the cable. So far, there is no particularly effective method to solve it. Either do the intermediate connector or replace the cable entirely. Wire and cable manufacturers generally take precautionary measures when there is water in the cables. There is a water hazard in the cable. Generally speaking, after the cable enters the water, the phenomenon of "water tree aging" will occur under the action of the electromagnetic field. The damage to the cable will only be a matter of time and will eventually lead to cable breakdown.
The reasons for water in the cable manufacturers: 1. When the cable is laid and stored, the cable ends at both ends are not sealed or the sealing is not good, and water vapor penetrates into the cable. 2. During the laying of the cable, the cable head is not well sealed and immersed in water, or when the pipe is laid, the outer insulation of the cable is broken and water penetrates into the cable. 3. After the cable laying is completed, the cable ends at both ends have not been made in time, and have been exposed to the air or humid environment for a long time. 4. Local cable breakdown occurred during the operation of cable power supply, and water penetrated into the cable.
Solution with water in the cable: 1. Make the cable head in time after the cable is laid, and complete the wiring to eliminate the hidden dangers in the bud. 2. If only the two ends of the cable enter the water, you only need to cut off both ends and reconnect the cable ends. 3. If the cable has a clear water entry point, you need to cut off the cable near the water entry point to make an intermediate joint. 4. It is inevitable that there is water in the outdoor cable well or cable channel. Try to use a bracket to hold the cable high. 5. Use special hot nitrogen to carry out the pressure drying process inside the cable. Generally, there is no such professional equipment. 6. Regularly perform pressure leakage test on the cable to ensure that the operating status of the cable is known in a timely manner.
