Nexans has been awarded a contract by EDF to construct a submarine power cable for the French island of La Reunion in the Indian Ocean.

The cable link will take a subsea route along the coast to connect the power production facility located at Le Port in the west of the island to the capital city of Saint-Denis, which requires most of the power available.

By choosing this subsea cable route, the construction of 20km of aerial power lines across a natural environment consisting of rugged, steep and mountainous terrain was avoided.

Nexans is manufacturing two 90kV subsea XLPE cables, each 17.3km in length, to provide a power link of around 100MW.

Each cable will include three phases with copper conductor cross-sections of 400mm2, resulting in a weight of 60kg per metre.

Nexans is providing a complete turnkey service for EDF including design and manufacturing of the cable, as well as laying and protection.

The cable will be delivered and installed at a water depth of up to 100m.

The La Reunion cables will be assembled in the specialised Nexans facility in Halden, Norway and will incorporate fibre-optic monitoring and control elements supplied by the Rognan plant, in northern Norway.

‘The La Reunion project is particularly challenging, not only due to the terrain but also the local climate, and is an illustration of our capability to implement power connection solutions in the most demanding global locations’, said Yvon Raak, Nexans senior corporate executive vice-president.
