Nexans, the worldwide leader in the cable industry, has been awarded a 35 million Euro turnkey contract by EDF to construct a new submarine power cable for the French island of La Réunion in the Indian Ocean. The cable link will take a subsea route along the coast to connect the power production area located at Le Port in the West of the island to the capital city of Saint-Denis which requires much of the energy. By choosing this subsea cable route, the construction of 20 km of aerial power lines across a natural environment made of rugged, steep and mountainous terrain was avoided.
Nexans is manufacturing two 90 kV subsea XLPE cables, each 17.3 km in length, to provide a power link of around 100 MW. Each cable will include three phases with copper conductor cross-sections of 400 mm2, resulting in a weight of 60 kg per metre - a total of 2.000 tonnes of cable.
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 attaining 100 metres.
The La Réunion cables will be assembled in the specialized Nexans facility in Halden, Norway and will incorporate fibre optic monitoring and control elements supplied by the Rognan plant, North of Norway.
"The La Réunion project is particularly challenging, not only due to the terrain but also the local climate, and is a perfect illustration of our capability to implement innovative power connection solutions in even the most demanding global locations," says Yvon Raak, Nexans Senior Corporate Executive Vice President. "We have a long standing working relationship with EDF and won this latest major contract following the successful completion of a number of similar projects."
