N2XS(FL)H

Medium voltage Power cable 12/20 kV (24 kV) with Cu conductor, XLPE insulated and LSZH outer sheathed

Application

Single-core medium voltage power cables with copper conductor, XLPE insulation and LSZH outer sheath, featuring radial and longitudinal water barriers for use in distribution networks and power generation units. The LSZH outer sheath makes the cable suitable for indoor installation, as well as for direct burial in the ground, outdoor installation, and installation in cable ducts.

Construction

Conductors: ETP copper, class 2 stranded and compacted, in accordance with EN 60228
Conductor screen: Extruded semiconductive cross-linked compound (XLPE-based)
Insulation: Cross-linked Polyethylene, XLPE type DIX-8
Insulation screen: Extruded semiconductive cross-linked compound (XLPE-based) + semiconductive water swelling tape + copper wires with counter helix of copper tape
Outer sheath: Halogen free compound, LSOH type HM4 with bonded aluminium-polymer water barrier, UV resistant
