HRN N.C5.364

VDE 0250/Teil 813

1-phase conductor: tinned copper fine-wired rope
2-semi-conductive layer: rubber compound at ethylene-propylene elastomere base (EPDM)
3-insulation: rubber compound at ethylene-propylene elastomere base (EPDM)
4-semi-conductive layer: semi conductive textile tape
5-inner sheath: EpN 64 - NR+SBR; EpN 65 - EPDM
6-electric protection: tinned copper wire concentrically around separator sheath
7-separator: polyester tape
8-separator sheath: rubber compound at ethylene-propylene elastomere base (EPDM), wrapped with semi conductive textile tape
9-control conductor: tinned copper wire concentrically around separator sheath
10-separator: polyester tape
11-external sheath: rubber compound at polychloroprene elastomere base (PCP)

Sheath colour: red
Flexible cable is intended for application in mines with methane pits. It is used under application of adequate cable controller of high voltage network, where application of armoured cables isnt possible because of site removal, and those are pit transformer stations for supplying of excavations and preparation sites. At laying and removal during operation, banding radius is at least 5D (D = external diameter).
nominal voltage: 3,6/6 kV
test voltage: 11 kV
standards: HRN N.C5.364; VDE 0250/Teil 813
Permissible conductor temperature: 90°C
