0.66/1.14kV and below fire-retardant coal mine shearer rubber flexible cable mark 

Identified mark of insulated core: using color OR printing numbers on the surface of insulated core.
If you use color to identify, the insulated color of single core cable is red or white.
Power core color of c able with 4 cores is red, white, light blue and black for earthing conductor.
If you print numbers on the surface of insulated core, power core of cable with 4 cores is 1, 2, 3 and 0 for earth- ing conductor.
Identified mark of cable:
Different cable sheath color will be used to identify cable under well with different voltage degree. Please see the following table.
