MINING POWER CABLES	Technical Data sheet

APPLICATIONS

YKGYyn-żo 0,6/1 kV are mining power cables intended to work in power engineering installations.

Cables can be applied in:

- opencast and underground mines, except explosive condition zones,

- underground mines in workings of class A coal dust explosion hazard.

Cables have positive Technical Opinion No. 2242/2011 regarding application in underground mines and Certificate No. 2242/A1/2011 issued by TI EMAG Institute.

CONSTRUCTION                                                                                                           

-  bare annealed copper conductors, meeting requirements of class 1 or 2 per PN-EN 60228,

-  PVC insulation, colours of insulation:

-  insulated conductors laid-up into a cable core,

-  inner covering on cable core, PVC or unvulcanised rubber,

-  special (oxygen index bigger than 29%) PVC cable sheath, yellow, other colours also available.

CHARACTERISTICS

Operating voltage Uo/U    0.6/1 kV
Voltage test    4 kV rms

Conductor temperature limit
      in work conditions          +70°C
      in short-circuit               +160°C

Temperature range
      during operation            from - 30 to + 70°C
      during installation          from   - 5 to + 70°C

Minimum bending radius      12 x cable diameter

Cable combustibility             flame retardant

Combustibility tests             PN-EN 60332-1-2, IEC 60332-1-2, PN-EN 60332-3-24, IEC 60332-3-24 (cat. C)

Reference standards           WT-TK-27

The cable meets requirements of the low voltage directive 2014/35/EU

* 1 second short-circuit current rating is calculated assuming that the temperature of power conductors during short-circuit equals the maximum conductor operating temperature under normal conditions.

Other cross-sections and conductor counts available on request.
