Shielding and Monitoring Reinforced Flexible Cable for Shearer with Rated Voltage of 1.9/3.3kV and Below

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

2. Implementation standards
MT818.1-2009 Cables for coal mines Part 1: General requirements for mobile flame-retardant flexible cables for coal mines.
MT818.3—2009 Coal Mine Cables Part 3: Shearer shielding and monitoring reinforced flexible cables with rated voltages of 1.9/3.3kV and below.

3. Features
The conductor of this cable adopts the same direction structure to improve the flexibility of the cable and reduce the outer diameter of the cable; the power core insulation adopts XJ-30A ethylene propylene insulating rubber; the power core adopts a metal fiber braided layer to improve the cable Mechanical properties: XH-21A neoprene rubber is used for the outer sheath, and the flame retardant grade meets the requirements of the MT386-2011 "Test Methods and Judgment Rules for Flame Retardant Cables for Coal Mines"
