APPLICATIONS

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

Cables can be applied in:

- w 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.

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.

AVAILABLE UPON REQUEST

YnHKGSX - 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).

YnHKGSXS - cross-linked polyethylene insulated cables (XS) of low capacitance and higher, up to 90°C, conductor temperature limit, designed to transmit signals over long distances. Cables are designed for operating voltages 300/500 V and 0,6/1 kV. Cable sheath made of special self-extinguishing and flame retardant PVC (Yn).

XnHKGSX - 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.
