CONSTRUCTION:
Conductor: multi-core conductor class 2,
copper XHP 81 or aluminium XHP 81-A
according to SRPS N.C0.015, IEC 60228.
Inner semi-conductive layer
Insulation: cross-linked polyethylene XLPE
Outer semi-conductive layer: extruded,
with wrapped semi-conductive tape over
extruded layer.
Electric protection: wrapped annealed copper wires with contra-helical copper tape or wrapped copper tape around each conductor (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 two steel tapes
Outer sheath: PVC compound
Sheath colour black, for use in mining red.
APPLICATION
For laying indoors, in ducts, in the open air, directly in earth, in urbane networks, industrial plants and power plants. Suitable for the networks which require minor reduction factor. Not provided for complicated conditions in terms of severe axial strains.
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)
