Terna, the European electricity transmission network operator Tyrrhenian Link named (Tyrene connection) 970 km long and 1000 MW With the installation carried out within the scope of the capacity project Sicily, Sardinia and Italy The pair will be connected by an underwater cable.
New generation cable technology used
High Modulus Synthetic Fibers (HMPE) created using a composite material based on non-metallic armored cableis touted as the next generation transmission cable technology. HMPE, low stretch ratio and high strength/weight ratio As a fiber with fatigue and wear resistant a material.
The subsea cables in the project will be installed and maintained at a depth of 2,150 meters, the deepest point ever reached by a power cable. Laying cables at these depths 50 percent lighter than steel It was made possible thanks to the innovative armor solution. The company’s state-of-the-art Leonardo da Vinci cable-laying ship was used in the mission.
Renewable energy sources such as solar and wind are growing rapidly in Sicily, Sardinia and especially Campania. Since these energy sources are irregular in nature, their connection to the grid is of great importance. Because, 1.7 billion Euro’luk The Tyrrhenian Link project is designed to increase electricity transmission capacity, support the development of renewable energy and improve grid reliability.
