Mcp Series Shearer Cable Due to the need of working environment, the cable is often bent, stretching causes the control line to break, and a short circuit to ground or phase.
The most common failures in coal mines are: mechanical damage, break down of joints or terminals, and short-circuit of single-wire cables to ground or phases. There are roughly the following types of failures:
1. The cable is directly affected by external forces and malfunctions, such as armored cable, mobile rubber cable, etc., top-down plate is broken; the hydraulic support, scraper transporter is out of order, the off-road (derailment) vehicle is damaged, the gun is broken, and laid. The cable bends too much and damages the lead package and insulation. The cable that passes through the wind wall or damper is crushed due to the curved shape of the roadway. Talk about coal mine (electricity, rubber sheath, control, communication) Cable faults and causes 2. The cable is faulty due to moisture and moisture, such as cable joints or terminal places where there is drip and water in the food and drink place, and the cable jacket is damaged by water soaking. The insulation of the power supply network is reduced, causing a relative or inter-phase short circuit. Why the shelf life of mcp Shearer Cable is short 3. The cable is faulty due to the insulation aging, such as the long service life of the cable and the aging caused by the overload for a long time.
4. Because of the frequent bending of the rubber sheath shearer cable, the control line is broken due to stretching, and a short circuit to the ground or phase.
5. Rubber cable hot or cold joints due to the poor quality of the joints to produce local heat or leakage.
Why the shelf life of mcp Shearer Cables is short? The reasons for the above-mentioned failures of cables for coal mining (power, rubber bushings, control, and communication) cable faults are as follows: Firstly, when laying cables, they are not operated according to the laying requirements of cables. The use is not in accordance with the requirements of the operation or maintenance; second, there is a defect in the cable manufacturing, so in order to prevent failures, according to the use of requirements on the one hand to choose different types of cables, and according to (coal mine electrical test procedures) provisions of the cable acceptance On the other hand, the maintenance of strong lines is well done.
