Copper cable 150 kV 2000 S (lead)
StandardsInternational : IEC 60840
Since the late 1960s, Nexans has been developing an entire range of XLPE insulated cables for high voltage-transmission. The cables consists of a stranded copper or aluminium conductor with an extruded insulation system. All our extrusion lines are equipped with multiple heads, which allows for simultaneous application of the insulation and the two semi-conductive layers.
In all lines, incoming materials are kept and handled in completely super clean and closed systems and the curing is always done under dry process. After the reticulation, particular care is taken on the degassing process. The cable is then further protected by a metallic shield and an outer sheath. Big unwind and take up stands allows for the manufacturing of long cable lengths.
