APPLICATIONS

YnHKGSLYkonożo-P are multipair, pair and overall shielded and YnHKGSLYkonożo-T are multitriple, triple and 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.

Shielded pair or triple structure substantially decreases mutual influence between signals transmitted along the cable.

The overall shield protects the cables against external electromagnetic interferences and prevents emission of interferences produced in the cables.

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, identification colour code:

                   pairs – black and brown insulation and white pair number printed on it,

                   triples – black, brown and blue insulation and white triple number printed on it,

- insulated conductors twisted into pairs or triples,

-  tinned copper wire braid shield of coverage bigger than 70% on pairs or triples (bare copper wire braid available on request),

- shielded pairs or triples laid-up in layers into a cable core, green-yellow protective conductor located in the outer layer, cables are made of  2, 3, 4, 5, 7, 8, 10, 12, 14, 15, 16, 18, 19, 21, 24, 25, 28, 30, 40 and 50 pairs or triples,

-  cable core wrapped in polyester tape,

-  tinned copper wire braid shield of coverage bigger than 70%,

-  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

YnHKGSLXkonożo-P, YnHKGSLXkonożo-T - polyethylene insulated cables (X) of low capacitance, designed to transmit signals over long distances. Cables are designed for operating voltage 300/300 V. Cable sheath made of special self-extinguishing and flame retardant PVC (Yn).

XnHKGSLXkonożo-P, XnHKGSLXkonożo-T - 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 300/300 V.
