Mine control cable selection regulations

1. In the vertical shaft or the shaft of the inclined angle of 45° and above, the high-voltage cable fixedly laid shall be made of steel wire sheathed non-drip lead-coated paper insulated cable, steel wire armored XLPE insulated cable or steel wire armored polychlorinated cable. Vinyl insulated cable.

2. In the horizontal roadway or the roadway with the inclination angle less than 45°, the fixed high-voltage cable should be made of steel belt armored lead-wrapped paper insulated cable, steel belt armored, non-drip, lead-wrapped paper insulated cable or steel belt. Vinyl chloride insulated cable.

3. For power cables of mobile substations, high-flexibility and high-strength mine-monitored shielded rubber cables must be used.

4. The low-voltage cable laid fixedly shall be made of armored PVC insulated cable, steel tape armored lead-coated paper insulated cable or mine non-flame-burning rubber sheathed cable.

5. For power supply cables with a voltage of 1140V and 660V or 380V power equipment for coal mining face, mine non-flame retardant shielded rubber cable with phase separation shielding must be used. Mine electrical equipment should be used for mine electrical equipment.

6, mobile and hand-held electrical equipment: coal mine underground should use a special phase-separated shield non-flame-burning rubber cable; other mines should use mining rubber cable.

7. When the cable is laid in bundles, it is advisable to use a mine flame retardant rubber cable.
