Record installations for Prysmian, a Milan-based multinational company specializing in the production and assembly of power and telecommunications cables. The company successfully carried out a trial installation of a 550-kilovolt HVDC (high-voltage direct current) cable at a depth of 2,150 meters, a new market standard for such types of cables. Credit to innovations in cable composition, which were designed with a synthetic fiber composite material. In addition, the non-metallic armor used can get up to 50 percent lighter than steel in water, and as a result allows installation and maintenance of the cable at a sea depth of more than 2,000 meters. The same technology has already been used in 2019 at 550 meters and in 2020 for the Crete-Peloponnese project at 1,000 meters. These innovations will be exploited in particular for the 1.7 billion Terna Tyrrhenian Link order awarded in 2021, a project to boost energy exchanges between Sardinia, Sicily and Campania. The cable-laying ship Leonardo da Vinci will be used for the operation.
