Islands to get submarine cable connection
90km of cable at depths of up to 1150m will be laid between Spanish islands and the north coast of Africa.
Cable systems supplier Prysmian Group will lay subsea cables between two Canary islands and another island and a coastal city in North Africa.
It will also lay about 11km of land cable.
The two contracts are worth approximately €250 million and have been awarded by Red Eléctrica de España, the Spanish power grid transmission system operator.
One cable will connect power between the islands of Tenerife and La Gomera and the second will connect the Spanish mainland to Ceuta, a Spanish city on the north coast of Africa.
Prysmian’s cable-laying vessel Guilio Verne will be deployed to lay the cables in 2025.
The first is a 66kV HVAC (high voltage alternating current) double circuit, three-core submarine power cable with EPR insulation and synthetic wire armouring, which Prysmian says will be laid at a world record depth (1150m) for this kind of cable.
The second cable is a 132kV HVAC double circuit, three-core submarine power cable with XLPE insulation and synthetic wire armouring and will be laid at about 900km.
The submarine cables will be manufactured at Germany’s Norderham Plant and Finland’s Pikkala Plant, which are both owned by the Prysmian Group. The land cables will be produced in the local plant of Vilanova in Spain.
