Mine cable blasting?
In the course of operation of wires and cables, such accidents often occur, especially when non-standard wires and cables are used. When the cable is in operation, when two-phase (and multi-phase) grounding or phase-to-phase short-circuit faults occur, the system is mostly tripped. This kind of failure phenomenon is commonly referred to as shot blasting. Now let's just say, what are the main factors that cause the "cable blasting"?
1. Short-circuit faults between the three-phase cores inside the cable, or one of the short-circuit faults on the outer jacket of the cable, will generate very large heat, causing the fault to burst. 2. For example, particles, impurities, bubbles or the like in the insulating layer, or external mechanical damage. 3, check the cable is bent too much to give the cable to hurt. 4. The bending radius is too small, mechanical external damage, DC resistance test ion release, rated current overload.
The cable blasting occurs during operation and causes a sudden trip of the system, which is extremely detrimental to production. We believe that if there are frequent shot-blasting failures in the cable system, it indicates that there are major problems in the construction, operation, maintenance, and management of the cable lines, and sufficient attention should be paid. After the repair work is completed, the cause must be carefully searched and eliminated. Avoid recurring shots.
