What are the main reasons for the bursting of wires and cables?

During the operation of wires and cables, accidents of this kind often occur, especially when non-standard wires and cables are used. When wires and cables are running, when two-phase (and multi-phase) grounding or interphase short-circuit faults occur, most of the systems trip and burst. Next, the Qingzhou cable manufacturer will talk about what are the main factors that cause "cable blasting"?

1. When the three-phase core wires inside the cable are short-circuited between each other, or one of the pair of cable sheaths is short-circuited, a very large amount of heat will be generated, causing the fault to burst.

2. For example, particles, impurities, bubbles, etc. in the insulating layer, or external mechanical damage.

3. Check whether the wire and cable are bent too much and the cable is injured.

4. The bending radius is too small, the mechanical external force is damaged, the ion release of the DC resistance test is not complete, and the rated current is overloaded.

The cable burst occurs during operation, which will cause the system to suddenly trip, which is extremely detrimental to production. We believe that if the cable system often has burst faults, it means that there are major problems in the construction, operation, maintenance and management of the cable line, and it should be paid enough attention. After the repair work is completed, the cause should be carefully found and eliminated. Avoid this type of accident from happening again. cable price list
