Mine flame retardant cables are referred to as mining cables for short. It is a rubber sheathed cable for coal mining that is manufactured by national standards. Mining cables are mainly used for movable laying cables for mining power plants with power frequency working voltage U0/U8.7/10KV and below.

In the mine power supply and distribution system, armored cables are generally used in the distribution lines of the DC high-voltage power supply and distribution system, and the repair rate is much less than that of the low-voltage power supply.

The power supply and distribution system in the mining area is a weak link in the power supply and distribution system, and the working environment is weak. Therefore, how to choose the model, specification and cross-section of the cable is closely related to the safety of the power supply and distribution system.

The selection of cable models is closely related to the reliability and safety of the power supply and distribution system and whether it is economical, scientific and reasonable.
