MINING POWER CABLES	Technical Data sheet

APPLICATIONS

YnHKGSLY 150/250 V, YnHKGSLY 300/500 V and YnHKGSLY 0,6/1 kV are 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. 05/53 regarding application in underground mines and Certificates No. 05/53/A1/2 and 05/53/A2/2 issued by TI EMAG Institute.

CONSTRUCTION                                                                                                           

-  flexible, multiwire conductors, stranded of bare annealed copper wires (tin-plated on request), meeting requirements of class 5 per PN-EN 60228,

-  PVC insulation, colours of insulation:

-  tinned copper wire braid shield of coverage bigger than 70% on insulated conductors (bare copper wire braid available on request),

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

-  cable core wrapped in polyester tape,

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

AVAILABLE UPON REQUEST

YnHKGSLX - polyethylene insulated cables (X) of low capacitance, designed to transmit signals over long distances. Cable sheath made of special self-extinguishing and flame retardant PVC (Yn).

XnHKGSLX - 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.
