Standard: SRPS N.C5.230
DIN VDE 0276-620; HD 620 S2
Nominal voltage U0/U: 6/10 kV
Test voltage: 21 kV
Conductor: multi-core conductor class 2,
copper XHP 48 (N2XSEY) or aluminium conductor XHP 48-A (NA2XSEY), according to SRPS N.C0.015, IEC 60228.
Inner semi-conductive layer: extruded
Insulation: cross-linked polyethylene (XLPE).
Outer semi-conductive layer: extruded layer
firmly attached to insulation, wrapped semi-conductive tape over layer
Electrical protection (screen): Soft copper wire
braid with counter-helix soft copper tape around each core or copper tapes around each core.
Filling: Extruded non hygroscopic layer
around the core.
Sheath: PVC compound
Sheath color black, for use in mining red colour.
For laying indoors, in cable ducts, outdoors,
as well as directly in the ground in local networks, industrial plants and power stations.
Laying on the ground caused by the mechanical
characteristics of PVC sheath.
