High-voltage cables for transmission

• Onshore AC transmission:
  • cables ranging from 60 kV to 500 kV, XLPE insulated,
  • used for power transmission from the onshore windpark substation to the central grid.
• Offshore AC transmission:
  • submarine cables ranging from 60 kV to 500 kVvarious designs available: 3-core XLPE cables (60-225 kV); single core XLPE up to 400 kV.
• Onshore and offshore DC transmission :
  • up to 500 kV
  • applicable for high transmission requirements and long distances
  • mass-impregnated cables with an Integrated Return Conductor, and Polymer-based insulated DC cables.

For Horns Rev, Nexans designed, manufactured and successfully type-tested a 21 km long 150 kV 3-core submarine cable, which was installed in three days between,land and an offshore substation, using a special cable-laying ship.
