Yes, mining cables belong to flame-retardant cables and must pass the national mining product safety certification.

flame retardant properties

Mining cables can self extinguish and limit the spread of fire in the event of a fire, meeting the definition of flame-retardant cables. The outer sheath is usually made of flame-retardant materials, which can effectively control the spread of fire even during combustion. ‌

Safety Certification

All mining cables must obtain a safety mark certificate issued by the National Mining Product Safety Mark Center to ensure that their flame retardant performance meets coal mine safety standards. ‌

structural characteristics

The structure of mining cables must meet the requirements of frequent movement, bending, and other working conditions. The outer sheath should be thickened and color coded to distinguish voltage levels, and the conductor temperature rise should be limited to below 70 ℃. ‌
