Information

There are four common faults in cable trays:

The first type of fault: the entire cable is blown or a phase is blown. This type of fault causes the current relay on the power distribution cabinet to operate, and the cable is seriously damaged in the fault.

The second type of fault: all phases of the cable are short-circuited. Similarly, such faults cause the current relay and voltage relay on the power distribution cabinet to operate, and the cable is also seriously damaged at the fault point.

The third type of fault: the cable bridge has only one phase open circuit, the current relay acts, and the damage at the fault point is lighter but the exposure is more obvious. It may be that the phase current is too large or caused by the quality of the cable.

The fourth type of fault: the internal short circuit of the cable, the appearance does not see traces, such faults are generally caused by the quality of the cable is relatively rare.
