Wire and cable fault analysis


Failure analysis is an important task to ensure the safe operation of cable line systems. Paying attention to this task is the basis for eliminating the causes of cable failures and is also a strong basis for improving cable technology, including line design, cable manufacturing and operation. Although the design of the cable structure, including accessories, has been carefully studied in the production process, and a series of relevant tests have been passed before it is put into operation, but these cannot fully simulate the long-term operation of individual actual cable lines, so the occurrence of cable lines Faults can be determined in which areas it is necessary to improve. If you only meet the analysis of rushing to repair the cable failure and ignore the cause of the failure, you will always be in a passive state and be exhausted.

Cable Line Obstacle Test


Cable line obstacle testing can use test methods such as DC bridges, AC meters, or line pulse testers. Compared with the general DC test method and AC test method, the pulse test method has the following advantages:

Repair cable internal fault


Remove moisture from the inside of the cable. When the cable near the joint or the cable is damp less than 3m, the lead sleeve can be longitudinally cut. After removing the moisture by the above method, use the longitudinally cut lead sleeve or a lead sleeve larger than the outer diameter of the cable lead sleeve to wrap it. Re-sealing. If the wet core wire exceeds 3m. Then reconnect this section of the cable.

Cable Connector Troubleshooting


Before cutting the joint, check whether there is water and moisture in the joint. If there is, do not use a blowtorch to cut the joint, because the blowtorch heats the moisture from both sides of the joint to the inside of the cable. It is best to use a hammer and cut. Cut the casing with a knife; if there is no moisture and moisture, you can use a blowtorch to scald the lead sleeve, remove the lead sleeve dirt, scrape off the rust spots, remove the solder slag, and remove it from the cable connection for reuse.
