Scotland Upgrades

Hellenic Cable’s responsibility included the design, manufacturing and supply of approximately 90 km of 11 kV and 33 kV composite submarine cables and associated accessories, as well as submarine cable repair joints for maintenance purposes.

Scottish & Southern Electricity Networks (SSEN) owns and operates the 11kV and 33kV subsea distribution network across the north of Scotland, with a combined cable length of 440 km, and the company’s routine inspections have identified that a number of the cables connecting Scotland’s island communities are due for replacement by 2023.

Under the contract, Hellenic Cables supplied approximately 90 km of 11 kV and 33 kV composite submarine cables and associated accessories, including transition joints for connecting the power cores and optical units of the submarine cables to the network as well as submarine cable repair joints, which will be used for maintenance purposes.

The cables were manufactured at Hellenic Cables’ plant in Corinth, Greece. With its highly skilled and experienced personnel, state-of-the-art facilities and adherence to best working practices, the plant can produce and test some of the longest continuous lengths of submarine cables worldwide.
