About the project

The Maritime Link is a 500 MW high voltage direct current (HVDC) that transport clean, renewable and reliable electricity from Newfoundland and Labrador to Nova Scotia and other energy markets in Canada and the North-eastern United States. For the first time in its history, the island of Newfoundland is connected to the North American transmission system. The Maritime Link also provide Nova Scotia with new access to clean renewable energy to offset coal fired generation and meets more stringent Canadian emissions requirements. The project included two 170 km subsea cables across the Cabot Strait, with almost 50 km of overland transmission in Nova Scotia and close to another 300 km of overland transmission on the island of Newfoundland.

Nexans' solution

Nexans designed, manufactured and installed two 200 kV HVDC power cables that spanned a subsea distance of approximately 170 km. Nexans supplied approximately 340 km of mass impregnated (MI) HVDC subsea and land cables together with fibre optic elements, transition joints for the sea and land cables, joints and terminations.
