Nexans has signed a subcontract with Hellenic Cables for the supply of a 420-kilometre mass-impregnated (MI) cable system as part of the Corinth–Kos electricity interconnection project in Greece.

The agreement forms part of a larger high-voltage direct current (HVDC) development connecting the Dodecanese islands with mainland Greece. Hellenic Cables is working in consortium with Asso.subsea on the project, which was awarded by Greece’s Independent Power Transmission Operator (IPTO).

The overall interconnection has a transmission capacity of 1 GW and operates at 320 kV, with the project scope comprising approximately 1,260 kilometres of submarine cable and 30 kilometres of land cable. Nexans’ subcontract specifically covers the supply of a 110 kV MI cable system, rather than the full interconnection.

The development is intended to strengthen electricity transmission infrastructure between mainland Greece and the Dodecanese, improving regional connectivity and supporting the integration of the islands into the national power system.

## Cable production and offshore preparations underway

According to Nexans, project-related activities have already begun on its MI cable production lines, alongside seabed survey operations. Manufacturing activity associated with the subcontract is expected to support production line utilisation from late 2026, throughout 2027 and until mid-2028.

The contract adds to the company’s involvement in high-voltage transmission infrastructure, particularly projects requiring specialised subsea cable technology. The agreement also brings together international cable manufacturing capabilities and Greek companies involved in submarine infrastructure development.

Pascal Radue, Executive Vice President PWR-Transmission at Nexans, said the project reflects increasing demand for high-voltage infrastructure connecting regions and strengthening electricity networks.

The Corinth–Kos interconnection is part of Greece’s wider efforts to improve electricity connectivity across its island regions. Its development involves extensive submarine cable infrastructure, making offshore surveying and installation activities important components of the overall project.

Nexans has not disclosed the financial value of its subcontract or provided a detailed delivery schedule for the cable system.

The agreement is expected to support the company’s manufacturing workload through the first half of 2028 while contributing to the development of the electricity interconnection between the Dodecanese and mainland Greece.
