A €5 million 400 MW cross-border transmission link between Switzerland and Italy is underway by cable company Nexans.

Azienda Elettrica Ticinese (AET), the power company for the Ticino canton in Switzerland, signed the turnkey deal for an interconnection project between Switzerland and Italy.

The new line, of an unprecedented scale in Switzerland, could become the first underground merchant line project completed in Europe.

Nexans will supply 27 km of 380kV XLPE cables with the 9 km link between the towns of Mendrisio in Switzerland and Cagno in Italy divided into 15 sections. Nexans will also supply 14 junction chambers, with 3 pre-moulded joints each, as well as all necessary connecting and grounding components.
