Prysmian Group has announced that the extra high voltage power cable link between Sicily and Calabria across the Messina straits has been successfully handed over to its customer Terna Spa Rete Elettrica Nazionale.
Prysmian developed and produced a double-circuit 380 kV HVAC (high voltage alternate current) land and submarine cable system installed along a total route of approximately 44 km – of which 38 km running under water – between the power stations of Villafranca Tirrena in Sicily and Scilla in Calabria. The project includes the installation of the first permanent monitoring system, an exclusive of Prysmian, carried out by ways of 18 Pry-Cam Grids devices installed along the entire land route section.
Prysmian installed the submarine cable with their own cableship Giulio Verne, the vessel with the largest operation capacity in the world in this sector. The land cables installation proved to be among the most technically complex ever, with operations carried out in a vertical shaft of 300 m and a 12% sloped and 2.8 km long tunnel.
Prysmian was awarded the 300 million euro contract in December 2009. The order book of Prysmian in the power transmission business amounts to 3.2 billion euro. With the goal of further strengthening its worldwide leadership in the industry, the Group is currently involved in important investment programmes both in terms of technology innovation (the announcement related to the first ever 700 kV HVDC cable system was released a few days ago) and of project execution, with the launch of a new cable laying barge.
