Fixed laying power cable for colliery is suitable for use in fixed installation in transmission/distribution lines for rated voltages less than 10KV such as the place from central distribution chamber to the electromechanical chamber, movable transformer substation,comprehensive mining workshop and switch cabinet. The cable has the characteristic of high frame retardancy.

Colliery PVC insulated flame retardant power cable(MT818.12-1999)

Colliery XLPE insulated flame retardant power calbe(MT818.13-1999)

Main properties

1)For the calbes are used in the mining of complicated conditions and inclement environment, abounded with gas and smut,easily caused exposition, the insulated plastic flame retardant power cables have the property of high flame retardant. Amone them,the one whose maximun cross-sectional area ins up to 50mm² should pass through The Combustion Testing Of A Type Collecting Electric Wire & Cable. If less than 50mm², it should pass through The Combustion Testing Of B Type Collecting Electric Wire & Cable.

2)The maximum temperature of the normal operating cable conductor or short(should not exceed 5 second)

For PVC insulated flame retardant power cable,the maximum temperature should not exceed

160 centi degree when short circuit. 90 centi degree for XLPE insulated flame retardant power cable, the maximum temperature should not exceed 250 centi degree?hen short circuit..
