Wedoany.com Report-Dec.31, French company Nexans announced that it has successfully laid a 500 kV high-voltage direct current submarine cable at a depth of 2150 meters in the Italian Tyrrhenian Link project, setting a new deep-sea installation record for this type of cable.

This submarine cable is a core component of an Italian cross-sea power interconnection project, with a total length of 970 kilometers and a designed capacity of 1000 megawatts. This installation is part of the western section of the project connecting Sicily and Sardinia. Nexans began phased construction in September 2025 and completed the deep-sea section work in December.

In a statement, Nexans said: "We have achieved this milestone in the Italian Tyrrhenian Link project thanks to our close collaboration with our customer, Terna SpA. This reflects years of engineering R&D results, the outstanding performance of Nexans Aurora, and the precise dedication and high sense of responsibility of all teams across the value chain."

The submarine cable laid this time aims to enhance the interconnection and power transmission capabilities of Italy's regional power grid. The breakthrough in deep-sea construction technology provides valuable experience for future high-voltage cable projects in similarly complex marine environments.

The Tyrrhenian Link project is scheduled to be fully operational in 2028.
