3 kinds of preventive measures for cable fault prevention and cable water leakage. After cable fault prevention and cable leakage, it is very troublesome to handle and detect. The general cable fault tester is not equipped with corresponding processing equipment. In the specific operation, if a part of the cable connector end leaks, it can be used again only by cutting off the front-end development. If the cable has leaked, the foundation cannot be used at this stage, so it can only be reported. Therefore, it is an appropriate choice to avoid cable leakage, and take preventive measures to prevent it from happening.

First, the cable joint should be kept sealed. The edge of the sawed cable, whether it is piled or laid, should be sealed with plastic, and a special type of sealing sleeve for the cable should be used to avoid the penetration of moisture and moisture. Make the cable joint immediately after laying the cable. Second, when purchasing cables, be sure to choose manufacturers with solid quality.

Because residues, air vents, etc. in the insulating layer are the starting point of water tree generation, the quality of the cable is particularly important to avoid water tree embrittlement. Third, improve the management method of the cable head manufacturing process. Once the cable leaks, the first penetration is usually the cable joint. Therefore, the cable head can be made well, which can increase the overall service life of the cable. For example, when the cable is detached from the semiconductor material layer, a few vertical marks are made on the semiconductor material layer, and then the semiconductor material is peeled off like a gossip.

However, when cutting with a knife, if the cut is too deep, the cable sheath will be damaged, creating opportunities for the formation of drainage trees. In addition, when soldering the wire, because the switching power supply cannot be found, the gas furnace will be used to melt the solder wire immediately. At this time, the flame will destroy the copper shielding layer and the cable sheath. Therefore, to avoid this kind of situation, the appropriate method can be used. Equipped with UPS, because the time required for soldering wire is generally only 10min, the output power is 500W. The PVC plastic pe corrugated pipe is selected. The pipe has corrosion resistance, smooth inner cavity, excellent compressive strength and ductility. Therefore, when the cable is buried and laid, the damage to the outer sheath of the cable can be greatly reduced.

Design of cable trenches (pipes) and cable wells. Due to the limitation of the standard, the cables are laid in the ground or in the cable trench, and most of them are buried in the ground. For example, in the rainy area in the coastal area, there is water stored in the cable trench or cable well for a long time. Because the depth of the cable trench or cable well will exceed the depth of the sewer pipeline, the drainage pipeline is very difficult, so in the overall planning, harmony should be carried out, which is beneficial to the drainage pipeline of the cable trench (well).

If it is not possible to ensure that the cable well does not store water, the middle connector in the cable well should be carried by a support frame. 3 kinds of preventive measures for cable leakage fault prevention of cable fault Shenzhen Noyafa Electronic Technology Co., Ltd.
