MINING POWER CABLES	Technical Data sheet

APPLICATIONS

YKGSYFoyn 150/250 V, YKGSYFoyn 300/500 V and YKGSYFoyn 0,6/1 kV are armoured, mining control cables 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” degree explosion hazard.

- underground mines in workings of class A 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 Certificate No. 06/09/A1 issued by TI EMAG Institute.

CONSTRUCTION                                                                                                           

-  bare annealed copper conductors (tin-plated on request), meeting requirements of class 1 per PN-EN 60228,

-  PVC insulation, colours of insulation:

-  insulated conductors laid-up in layers into a cable core, cables are made of  3, 4, 5, 7, 10, 12, 14, 16, 19, 21, 24, 27, 30, 33, 37, 40, 44, 48, 52, 56, 61, 65, 70 and 75 conductors,

-  inner PVC sheath,

-  galvanized steel wire armour,

-  special (oxygen index bigger than 29%) PVC cable covering, black (RAL 9005) or blue (RAL 5015 – for intrinsically safe circuits), other colours also available.

AVAILABLE UPON REQUEST

YKGSXFoyn - polyethylene insulated cables (X) of low capacitance, designed to transmit signals over long distances. Cables are designed for operating voltage 150/250 V. Cable sheath made of special self-extinguishing and flame retardant PVC (Yn).

XnKGSXFoxn - halogen free cables of reduced combustibility, sheathed with special halogen free material (Xn), applied when higher safety in case of fire is required. The cables are flame retardant, their smoke emission in fire is low and released gases are not corrosive. Cables are designed for operating voltage 150/250 V.
