How to detect fireproof cable failure

1. Cable fault diagnosis

The diagnosis of the nature of the cable fault is to determine the type and severity of the fault so that the tester can prescribe the right medicine and choose the appropriate cable fault location and location method.

2. Cable fault location

Cable fault location is also called rough measurement. An instrument is used to determine the fault distance at one end of the cable. The common fault location methods on site include classical bridge method and modern traveling wave method.

3. Cable fault fixed point

Cable fault location is also called precise measurement, which is to find out the general location of the fault point according to the fault location result and the path direction of the fireproof cable. In a small range, use the discharge acoustic method or other methods to determine the fault The exact location of the point.

Conclusion: In the process of using fireproof cables or power cables, if you encounter a failure, you should notify the maintenance and emergency repair department in time, and then carry out emergency plan operations in advance to avoid greater economic losses and secondary disasters.
