Three. Mine communication cable - mine use flame retardant communications cable products:

MHYV-Lane Inclined electrical and mechanical chamber.

MHYAV-for wet inclined shaft or drift.

MHYA32-for inclined or vertical shaft.

Four. Ore - coal mine fire-retardant communication cable installation and laying of communication cables:

A. Cable to allow long-term operating temperature of -40 to +50 ° C, monthly mean relative humidity of 95% (+25 ° C);

Two. Cable to allow the laying and installation of temperature should be not less than -10 ° C;

3. Cable minimum bending radius: MHYV type 10 times the cable diameter, other models for the outer diameter of 15 times.

VII. Mine communication cable - coal mine retardant communication cable transport and storage precautions:

The cable is suitable for all means of transport of the water. Land empty, should be noted that in the process of transport and storage:

A. To prevent moisture intrusion cable;

Two. Prevent severe bending and other mechanical damage;

3. Prevent heat and sun exposure;

4. The cable hoisting should use special lifting equipment, prohibited level hanging line disk or directly from high-altitude shirk cable
