Hellenic Cables, acting as main EPCI contractor for IPTO, completed the installation of the new 150 kV high‑voltage submarine cable system between Kyllini and Zakynthos, delivering a turnkey replacement for the ageing 1980s interconnection. The in‑house engineered XLPE three‑core cable, manufactured at Hellenic Cables’ Corinth plant and integrated with optical fibre over a route of about 23 km, was fully installed by the company’s own teams and an installation subcontractor as part of a wider project to upgrade the Ionian Islands’ transmission system.
