  • Product Description
    • Commodity name: Metal shielded rubber sheathed flexible cable for shearer with rated voltage of 1.9/3.3kV and below
    • Commodity ID: 1171377247374430208

    1. Scope of application
    This product is suitable for the power connection of shearers and similar equipment with rated voltage Uo/U of 1.9/3.3kV and below.

    2. Implementation of standards
    MT818.1-2009 coal mine cables-Part 1: General provisions for flexible mobile fire-retardant cables for coal mines.
    Cables for MT818.4-2009 coal mines-Part 4: Metal shielded flexible cables for shearers with rated voltage of 1.9/3.3KV and below.

    3. Features
    The conductor of this cable adopts the same direction structure, which not only improves the bendability of the cable, but also reduces the outer diameter of the cable. XJ-30A ethylene-propylene insulating rubber is used for power wire core insulation. The metal fiber braided reinforcement layer is used outside the power wire core to improve the mechanical properties of the cable. The outer protective layer is made of XH-03A neoprene, and the flame retardant grade meets the requirements of the MT386-2011 "Test Methods and Judgment Rules for Flame Retardancy of Flame Retardancy of Flame Retardant for Flame Retardant for Flame, ensure the safety and reliability of cable operation.
