MINING POWER CABLES	Technical Data sheet

APPLICATIONS

YHKGSYFoyn 150/250 V, YHKGSYFoyn 300/500 V and YHKGSYFoyn 0,6/1 kV are armoured, mining control cables with individually shielded wires intended for control, communication, measuring and monitoring systems in mines.

Cables can be applied in:

- opencast and underground mines, except explosive condition zones.

- underground mines in their non-methane and methane fields in areas of „a”, „b” or „c” degree explosion hazard.

- underground mines in workings of class A or B coal dust explosion hazard.

- intrinsically safe circuits in opencast and underground mines in explosion hazardous areas.

- intrinsically safe circuits in underground mines in areas classified as „a”, „b”, or „c” degree explosion hazard.

- in vertical mine workings and with an angle of inclination over 45°.

Cables can not be used for power supplying in power engineering installations.

Galvanized steel wire armour provides carrying an axial load of the cable during exploitation. It also offers enhanced protection against mechanical damages.

Cables have positive Technical Opinion No. 06/09  regarding application in underground mines and Certificates No. 06/09/A1 and 06/09/A2 issued by TI EMAG Institute.

CONSTRUCTION
