Metal Shielded Rubber Sheathed Flexible Cable of 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.
MT818.4—2009 Coal Mine Cable Part 4: Rated voltage 1.9/3.3KV and below coal mining machine metal shielded flexible cable.

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-03A 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". The use of the above materials and technologies guarantees The safety and reliability of cable operation.
