Standard: SRPS N.C5.230
DIN VDE 0276-620; HD 620 S2; IEC 60502-2
Nominal voltage U0/U: 6/10 kV
Test voltage: 21 kV
CONSTRUCTION
Conductor: multi-core annealed copper conductor class 2, (XHP 85) or aluminium
(XHP 85-A), according to SRPS N.C0.015
(IEC 60228).
Inner semi-conductive layer: extruded.
Insulation: XLPE compound.
Outer semi-conductive layer: extruded,
with lapped semi-conductive tape over
extruded layer used as bedding for electric
protection.
Electric protection: wrapped annealed copper
wires with contra-helical annealed copper
tape or wrapped copper tape around each core (SE).
Core: 3 cores are stranded together.
Separate sheath: extruded, non hygroscopic
layer over the core that completely fills the
space between the cores.
Armour: wrapped flat zinc-plated steel wires
with contra-helical zinc-plated steel tape
Outer sheath: PVC compound.
Sheath colour black, for use in mining red.
APPLICATION
In urban networks, industrial plants and power
plants, when the cable is exposed to severe
mechanical tensile strains during laying down
or use. For laying in ducts, in the open air and
in earth.
Permissible conductor temperature:
– max operating temperature +90°C
– in short circuit (max 5 s), max +250°C
– short-term overload in emergency operation to
+230°C
Permissible environment temperature:
at laying and handling, min +5°C
BENDING RADIUS (min.):
– 15D (D – cable diameter)
