Cable fault repair manufacturer Cable damage degree Cable fault repair manufacturer 1. Single point fault The power cable fault is at a certain point in the cable, whether it is a single-phase-to-ground, phase-to-ground or mixed fault. In practice, most cable faults are single-point faults. 2. Compared with single-point fault, multi-point fault refers to that there are multiple fault points at different distances from the measuring end (terminal end) in the same cable.
3. Large-area or long-distance faults are relative to point faults in cables. Large-area faults usually refer to damage to a certain section of the insulation layer in the cable, such as large-area moisture-damaged faults in common cables. 4. The quality problem does not belong to the category of cable fault classification, but in fact, it is often found in our country that after some user cables are used for a short period of time, the dielectric strength of the main insulation layer of the entire cable decreases, and the leakage current is very large. In the case of leakage failure. It is sometimes difficult for users to distinguish whether it is a fault point or a quality problem in the field.
