Single-Core Cu/XLPE/CWS/LW/PE MV Cable (20.3/35 kV)

Property Specification
Type: N2XS(FL)2Y , Cu/XLPE/CWS/LW/PE (IEC)
Standards: IEC 60502
Construction: Copper conductor, inner semi-conducting layer, XLPE insulation, outer semi-conducting layer, semi-conductive water-swelling tape, copper screen, copper binder tape, water-swelling tape, aluminum tape, PE outer sheath
Applications: Featuring exceptionally low dielectric losses, these cables are ideal for power distribution networks subject to rapid load variations and high short-circuit levels in commercial, residential, and industrial settings. They are suitable for cable ducts, direct underground installation, or outdoor exposure in open air. Should physical damage break the sheath and allow water entry, the swelling tape swells rapidly to seal the area, blocking longitudinal water migration along the cable.
