7 XLPE DATASHEET | Land CONDUCTOR Bare copper wires filled with water swellable tapes, with nominal cross-section area up to 4000 mm². Aluminum is also available. INSULATION Low peroxide XLPE. METALLIC SHEATH The smooth metallic sheath is constituted by a longitudinally welded aluminum tape (WAS) applied over the outer semiconductive layer and water barrier, to provide water tightness, mechanical protection and to carry fault currents. OUTER SEMI-CONDUCTIVE LAYER Water-swellable tapes and extruded semi-conducting screen layer, to have a smooth electrical interface with insulation. OUTER SHEATH An extruded layer of red or black colored high density polyethylene compound is provided over the metallic sheath. An extruded black semi conductive layer can be applied over the outer sheath for after installation tests. Flame retardant and low smoke versions are available. Dimensional data for 3000 mm2 copper Electrical data for 3000 mm2 copper Indicative diameter 140 mm Indicative cable weight 40 kg/m Ohmic resistance 0.0060 Ω/km Coaxial inductance 0.14 mH/km Capacitance 0.24 µF/km INTEGRATED FO CABLE Up to 4 integrated fiber optic elements for monitoring purposes, able to accommodate both multi-mode and single-mode fibers. INNER SEMI-CONDUCTIVE LAYER Water-swellable tapes and extruded semiconducting screen layer, to have a smooth electrical interface with insulation.
