Rated voltage 1.9/3.3kV mobile metal shield rubber sheathed flexible cable


Key words:



  • Product Description
    • Commodity name: Rated voltage 1.9/3.3kV mobile metal shield rubber sheathed flexible cable
    • Commodity ID: 1171377250104922112

    Scope of application
    This product is suitable for power connection of underground mobile coal mining equipment with rated voltage of 1.9/3.3kV.

    Executive standard
    MT818.1-2009 cables for use in coal mines-Part 1: General provisions for mobile flexible cables for use in coal mines.
    MT818.7-2009 cables for coal mines-Part 6: Shielded flexible cables with rated voltages up to and including 6/10kV.

    Features
    The conductor of this cable adopts the same-direction stranded structure, which not only improves the flexibility of the cable, but also reduces the outer diameter of the cable. The power wire core insulation adopts XJ-30A EPDM rubber insulation. The outer protective layer adopts a self-developed flame retardant formula, and the flame retardant grade meets the requirements of the MT386-2011 "Test Methods and Judgment Rules for Flame Retardancy of Flame Retardant Cables for Coal Mines". The safety and reliability of cable are ensured by adopting the above materials and technology.

    Mobile metal shielded rubber sheathed flexible cable for coal mine

    Power connection for underground mobile coal mining equipment with rated voltage of 1.9/3.3kV.

    Cable working conditions
    1. The rated voltage Uo/U is 1.9/3.3kV.
    2. The minimum bending radius of the cable is 6 times the diameter of the cable.
    3. The ground core of the cable must be well grounded.
    4. Frequency voltage test

    The insulated power wire core can withstand the power frequency voltage test specified in Table 7 without breakdown.
