Description
Prysmian led the HVDC cable system for the SAPEI interconnector linking Fiume Santo in Sardinia with Latina on the Italian mainland. The system comprises approximately 420 km of submarine route and 15 km of land route, configured as a +/-500 kV, 1,000 MW bipole with two parallel cables, making the Tyrrhenian Sea crossing the deepest operational power cable in the world at around 1,600 m water depth. Of the total 840 km of subsea cable required (420 km x 2 poles), Prysmian manufactured approximately 515 km at its Arco Felice factory, with the remaining 325 km manufactured by Nexans at its Halden factory. Prysmian carried out the full marine installation using its cable-lay vessel Giulio Verne and supplied 30 km of land cable for the two-pole link.
