Application
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:
• 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. 7305/2022 regarding application in underground mines
and Certificates No. 7305/06/09/A1/2022 and 7305/06/09/A2/2022 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.
