Submarine cables are used to link islands, between platforms, submarine installations, across fjords and over the sea for hundreds of kilometres. High quality and reliability are extremely important design criteria for Nexans submarine cables and umbilicals.

From 6 to 525 kV
Nexans offers a complete range of submarine power cables, from 6 to 525 kV.
Adapted to customers' needs
The insulation system is for each implementation adapted to the customers' needs, providing solutions for both AC and DC, by paper/oil or extruded polymer insulation systems. With our factory especially designed for manufacturing long lengths the limitations are more of a physical or geographical nature than manufacturing capacity.
Combines different elements in one cable
Our multiple core cables can contain power phases, optical fibre steel tubes and high pressure steel tubes for fluids to become what we denominate a power umbilical, or any combination of these elements.
Connect over long distances and to deep water
We have developed cable systems operating at AC or DC for very long distance connections. DC cables are now applied for over 500 km while 3-core AC cables for over 100 km are being designed. Higher voltages are sought after also for submarine applications in deep water.
Offshore windmill farms
In order to avoid use of land and to reduce noise and visual pollution there is today a trend to move offshore. Several large-scale offshore windmill farms have now been built. The transport of power from the windmill farm to the grid on land requires the use of submarine power cables. Nexans' vast experience with composite 3-core XLPE and fibre optic submarine cables have made us a major supplier to this market and to the offshore market of long AC and DC submarine power cables.
Link between turbines
The voltage for offshore windmill farms is typically 36 kV AC for the link between the individual turbines in the farm 
 
Power transmission
Typically 132-245 kV AC for the transmission of the power from the offshore substation to the  onshore grid. This means that our 3-core XLPE cables are very well suited for the purpose.
