Special rubber mining cables

HRN N.C5.360

VDE 0250/Teil 812

1-phase conductor: tinned copper fine-wired rope
2-control conductor: tinned copper fine-wired rope
3-protective conductor: tinned copper fine-wired rope
4-separator: polyester tape around phase conductors
5-insulation: rubber compound at ethylene-propylene elastomere base (EPDM)
6-semi conductive layer: rubber compound at ethylene-propylene elastomere base (EPDM)
7-semi-conductive layer over phase conductor insulation: semi conductive textile tape
8-semi-conductive layer over around cable core: semi conductive textile tape + polyster tape
9-inner sheath: rubber compound at natural and styrene-butadiene elastomere base (NR+SBR)
10-separator: polyester tape
11-sheath: rubber compound at polychloroprene elastomere base (PCP)

Sheath colour: yellow
Flexible cable is intented for application in mines with methane pits. It is used for all drives where usage of cable controller and remote-control usage are indicated. Permissible bending radius at removal during operation is 2.5D, at what radius the cable can sustain 5000 single bending cycles without inner damages (D=external cable diameter). Construction 3x6+2,2,5+6mm2 is not according to HRN and it has been specially developed for drilling machines. EpN 62 construction enables application of cable controller and drilling machine control.
