Turkish link

Following installation and testing of the Çanakkale II submarine cable link, Prysmian Group commissioned and energized the system at a ceremony attended by the customer TEİAŞ, the Turkish electricity transmission corporation. TEİAŞ awarded the contract to Prysmian in December 2014 for the design, supply, installation and commissioning of the HV submarine cables interconnection with a double circuit 380kV from S/S Lapseki 2 to S/S Sütlüce 2 between Europe and Asia across the Dardanelles strait in Turkey. This second double circuit link across the Dardanelles strait complements the existing double circuit interconnection that Prysmian Group executed under the first contract awarded by TEİAŞ, commissioned in August 2015.

common with the Çanakkale I project, the link has a double 400kV AC power transmission circuit with a rating of 1,000MW for each circuit. For the 4.1km subsea route, six XLPE power cables and two submarine fiber optic cables were laid at a maximum sea depth of 90m. Circuits were completed by 1.5km of underground XLPE power cables. “The submarine power cables and underground power cables used in the project were interconnected at water level landfalls with special sea/land transition joints produced by Prysmian,” he concluded. Installation was performed by Cable Enterprise, under the management of Prysmian Powerlink, with land activities supported by Türk Prysmian Kablo.
