Performance analysis of mining rubber cable

Mine rubber sheathed cables are mainly used for the power lines of mining machinery that are not fixedly installed. Tai'an Hongjian Cable Co., Ltd. produces mineral rubber sheathed soft cables with three characteristics: First, flame retardancy, that is, non-flammability: the second is weather resistance, not afraid of hot and cold wind and snow and rain; Third, good mechanical properties, namely Resistant to friction, resistant to extrusion, resistant to rewinding. Due to the harsh environment of use and non-stop winding, the service life of the cable is shortened. If the fixed laying can be used for more than ten years, but the practice of the mine proves that the life of the mine rubber flexible cable is generally only a few months. It must also be stated that the flame retardancy of the cable is not non-combustible, but it is unnatural and does not prolong combustion. When Huang Jing appears a fire, as long as the power supply is cut off and the external fire source is removed, the burning cable will self-extinguish, and the flame retardancy is not explosion-proof. High quality cables are used normally and will not burn or explode. However, poor quality cables or improperly used cables may burn or explode. Just as steel would not burn, steel collisions will produce sparks.

Mine rubber cable safety precautions

1, buy high-quality cable, do not buy inferior cable

2, the correct choice of cable model

3, correct wiring, solid and reliable contact, pay attention to the protective box shielded wire is reliably grounded

4, the correct use of cable, no overload operation

5, always check the cable is damaged, replace the cable immediately, is strictly prohibited running sick
