FlameRetardant Mine Cable

Mine cable, known as coal mineused cable, it is referred to as those electric wires for coal mining plantssuch as coal cutter, coal preparation plant, lighting equipment, signaling equipment,electric drill, cap-lamp, etc. We are able tomanufacture a wide range of flame retardant mine cables. The following typesare available: M, MCP, MZ, MZP, MYP, MCPTJ, MYPJ, MVV, MKVV, MYJV, MKYJV, MHYVand UGF. We can supply high voltage mine cable, 10kV rubber cable, 6kV minecable, mobile crane cable, mining flame retardant cable, etc. Our flameretardant mine cables are all manufactured in strict accordance with theMT818-1999 standard.
