APPLICATIONS
YKGSYektyn 150/250 V, KGSYektyn 300/500 V and YKGSYektyn 0,6/1 kV are overall shielded, 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”, „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.
Cables can not be used for power supplying in power engineering installations.
The overall shield protects the cables against external electromagnetic interferences and prevents emission of interferences produced in the cables.
Cable inner sheath offers enhanced protection against mechanical damage.
Cables have positive Technical Opinion No. 06/09 regarding application in underground mines and Certificate No. 06/09/A1 issued by TI EMAG Institute.

AVAILABLE UPON REQUEST
YKGSXektyn - 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).
XnKGSXektxn - 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.
