Standard: SRPS N.C5.220
DIN VDE 0276-620; HD 620 S2
IEC 60502-2
Nominal voltage U0/U: 6/10 kV
Test voltage: 21kV
CONSTRUCTION:
Conductor: multi-core conductor class 2, copper PHP 48 or aluminium conductor
PHP 48-A, according to SRPS N.C0.015,
IEC 60228.
Inner semi-conductive layer
Insulation: special high-voltage PVC
compound.
Outer semi-conductive layer: extruded,
with wrapped semi-conductive tape over
extruded layer.
Electric protection (sreen): wrapped annealed copper wires with contra-helical annealed copper tape or wrapped copper tape.
Core: 3 screened cores are stranded together.
Filling: extruded, non hygroscopic layer
over the core that completely fills the space
between the cores.
Outer sheath: PVC compound.
Sheath colour black, for use in mine red.
APPLICATION:
Indoors, in ducts, in earth, in the open air
in distributive lattice, industrial plants and
power plants. Laying down, directly into the
earth, is restricted by mechanical properties
of PVC sheath.

– in short circuit (max 5 s)
max +160°C
Permissible environment temperature:
at laying and handling, min +5°C
BENDING RADIUS (min.):
– 15D (D – cable diameter)
