It marks a first of major significance in Europe: using a road tunnel for cable installation. On behalf of the federal government, Swissgrid evaluates every grid project to determine whether synergies with other infrastructure—such as rail or road tunnels—can be leveraged. Combining infrastructures often contributes to landscape preservation and more efficient land use. Nexans will supply a total of 57 km of extra-high voltage cable for this operation, working with its bases in Charleroi (Belgium), which will manufacture the cable, and in Cortaillod (Switzerland), which will handle the project engineering and installation as well as supply accessories...
