What Hellenic Cables S.a. Hellenic Cable Industry Single Member S.a. does

Hellenic Cables S.A. (Hellenic Cable Industry Single Member S.A.) is a Greek-headquartered, privately held industrial cable manufacturer founded in 1950 and operating as the wholly-owned cables segment of Cenergy Holdings SA (listed on Euronext Brussels and the Athens Stock Exchange, part of the Viohalco group). The company designs, manufactures, and sells low-, medium-, high-, and extra-high-voltage (up to 500kV) power cables, submarine cables (inter-array and export), telecom and optical fibre cables, and plastic/rubber compounds for cable insulation, serving European and North American energy utilities, transmission system operators (TSOs), distribution network operators (DSOs), offshore wind developers, and construction/infrastructure customers.

Its core technology centres on vertically integrated cable manufacturing across five Greek production facilities (Fulgor's submarine cable plant in Corinth with in-house copper and aluminium casting; power and fibre optic cable plants in Thiva and Eleonas; a compounding plant in Oinofyta), a wood packaging subsidiary in Bulgaria (Lesco EOOD), and a power/telecom cable plant in Romania (Icme Ecab), with a new US manufacturing facility under development in Baltimore, Maryland. The Fulgor Corinth facility is notable for producing extra-high-voltage submarine cables up to 500kV in very long continuous lengths without factory joints, leveraging a year-round-accessible private port for direct loading onto installation vessels — among the largest cable loading facilities globally.

The company earns revenue through direct enterprise field sales to grid operators, TSOs, DSOs, and offshore wind developers via competitive tenders, framework agreements, and EPCI (Engineering, Procurement, Construction, Installation) turnkey contracts, complemented by European sales offices in Italy, France, Germany, and the UK. Pricing is per-project and not publicly disclosed. Major recent awards include an ~EUR 1.15 billion IPTO framework for Greek island interconnections (June 2026), an 8-year framework with Alliander (2026-2034), the East Anglia TWO inter-array contract (Seaway7), and BC-Wind EPCI contracts (DEME/Ocean Winds). Since 2012, the company has executed an investment plan exceeding EUR 800 million to upgrade its production sites.
