January 18, 2018 – Nexans announced it has completed delivery of two 200-kV mass impregnated (MI) HVDC submarine cables as part of the Maritime Link Project conducted by NSP Maritime Link Inc., an indirect subsidiary of Emera Inc.

“We are thrilled to be part of this exciting project and we are happy to have completed the installation of these two submarine cables, the longest in Northern America, after almost 600,000 hours of designing, manufacturing and laying works,” said Nexans’ Geir Korstad.

Starting in late April 2017, Nexans installed the submarine cables in the Cabot Strait to a depth of about 470 metres, thereby electrically interconnecting the provinces of Nova Scotia and Newfoundland & Labrador for the first time. The final high-voltage tests were successfully conducted on the link in September 2017.

Each cable is 170-km long and weighs about 5500 tons.

The Maritime Link Project is a new 500 MW HVDC interconnection that consists of converter stations and associated high-voltage alternating current (HVAC) switchyards, as well as two HVDC transmission lines, a 230 kV HVAC transmission line, and associated infrastructure.
