What if there is no fault point exposed on the cable surface
There will always be such and such faults on the cable. Some cables only have some faults on the surface, so the staff will clearly find them. However, some cables have no fault points exposed on the surface, so the staff can't find them. What should we do at this time?
For the cable with no fault point exposed on the surface, in addition to checking the data and verifying the cable name, the maintenance personnel must also identify it with the cable identifier to distinguish it from other live cables in operation. Especially when there are many cables in the unified section, it is very important to strictly distinguish the cables to be inspected from other live cables.
