FULGOR is part of the HELLENIC CABLES Group, which has been a leading manufacturer of cables for more than 60 years. It is the sole producer of cross linked polyethylene (XLPE) insulated high and extra high-voltage underground cables, medium / high-voltage and optical fibre submarine cables, and enamelled wires.

The company’s wide product range is sold internationally under the CABLEL trademark, it extends to PVC, EPR and XLPE-insulated power cables, rated up to 500kV, marine and low smoke halogen free cables, fire resistant cables, telecommunication, signal and data cables with copper conductors or optical fibres and includes fire retardant halogen-free plastic and elastomer compounds and enamelled wires.

Wires and cables can be supplied to a variety of international standards, including: VDE, CEI, NF, SEN, BS, UL, NEMA, JIS, ASTM, DIN and ELOT. Many of the company’s products are certified from ELOT, BASEC, VDE, IMQ, NF-USE, Network Rail, KEMA, DNV and UL.

FULGOR offers turnkey capabilities for subsea projects.
The company supplies a range of medium-voltage subsea cables.
FULGOR provides optical fibre submarine cables for repeaterless links.
Composite power / optical fibre medium-voltage subsea cables.
High and extra high-voltage AC and DC XLPE insulated subsea cables and umbilicals are used for offshore windfarms and the oil and gas industry.

All CABLEL enamelled wires are manufactured and tested to IEC 60317-0-1; customers may also request any other recognised international standard.

Submarine interconnection and turnkey solutions

FULGOR was established in 1957 and has been a member of the HELLENIC CABLES Group of companies since August 2011. The company strongly contributes to the group’s export orientation and enhances it’s portfolio of high value added products.

The company’s manufacturing plant is occupying an area of 220,000m² by the sea at Soussaki , Corinth, Greece. The company owns a private dock and provides facilities for the direct loading of submarine cables onboard laying or freight vessels.

Medium-voltage submarine cables

Since 1972, FULGOR S.A. has manufactured more than 980km of submarine power cables with rated voltage up to 33kV. The produced cables are 6kV-33kV, three-core armoured cables with copper or aluminum conductors, insulated with oil impregnated paper tape insulation, lead covered (PILC), XLPE with copper wire screen and laminated core sheath or lead sheath or EPR ‘wet type’ design without a radial metal sheath water barrier.

The cables are produced in long continuous lengths due to the development of flexible factory joints. For each cable type the company has developed repair and land-submarine cable transition joints and provides trained personnel for their assembly.

In case of long continuous lengths, the cables are loaded directly on board the cable laying or freight vessel through a dedicated loading line. For shorter lengths the cables are wound on drums or coiled in transportable baskets and they are shipped directly to the work site.

Optical fibre submarine cables for repeaterless links

Since 1992, FULGOR SA has manufactured more than 2,200km of optical fibre submarine cables with varying core structures and types of armouring, while it has installed approximately 1,000km of these cables as a turnkey project contractor for repeaterless links.

Currently in production are light weight armoured (LWA) single and double armoured designs which include at the centre of the cable an optical core made of an hermetically sealed stainless steel tube which contains up to 48 single mode optical fibres. The optical fibres are placed loosely inside the tube with excess length and are surrounded by a filling compound (jelly) which includes an hydrogen scavenger. Over the optical core the successive protective layers are applied.

Composite power / optical fibre submarine cables

The first composite power/optical fibre submarine cable was manufactured and installed by FULGOR in 1995.

The construction of composite power / optical-fibre submarine cables is similar to that of standard submarine power cables, including additionally in their structure one or more optical units. The optical units are stranded during manufacturing of the cable between the outer interstices created by the insulated cores of the cable. For relevant short distances, multimode fibres may be used; with single mode fibres are used for long-distances.

Turnkey solutions for submarine power cables

In 1972, FULGOR undertook its first turnkey project for the supply and installation of 20kV submarine power cables to interconnect several islands in the Aegean Sea on behalf of DEI (the Public Power Corporation of Greece). Since then, the company has used its own specialised assets, trained personnel and well-proven subcontractors and it has successfully completed a large number of turnkey projects mainly in Greece and in other European countries.

The capabilities of the company in submarine cable projects include:

  • Design and engineering of the system
  • Cable route survey
  • Design and manufacturing of suitable cable types according to cable route survey results
  • Loading and transportation of the cables onsite
  • Installation of the cables with the use of specialised cable laying vessels
  • Protection of the cables along the cable route by simultaneous or post-lay burial
  • Installation and protection of the land cable segments
  • Supply and installation of repair-joints, transition joints and cable terminations
  • Supply and installation of terminal equipment
  • Testing and commissioning of the system
  • Project management
  • Training of the customer personnel in the operation of the system
  • Provision of maintenance and repair solutions to the customer

Insulated submarine cables and umbilicals

FULGOR is currently expanding its current submarine cable production capabilities to include the manufacture of static and dynamic type HVAC and HVDC XLPE insulated submarine cables and umbilicals, in order to participate in national and international turnkey submarine cable and subsea pipe interconnection and offshore projects such as:

  • High and extra high-voltage AC XLPE insulated submarine cables: 45kV to 275kV three-core or single-core (up to 500kV) armoured cables with lead sheath. The cables may contain integrated FO elements
  • High-voltage DC XLPE insulated submarine cables: 80kV to 320kV single core armoured cables with lead sheath
  • Umbilicals: static and dynamic umbilical cables with power, control elements and plastic or steel tubes for the transmission of fluids


  • Ravn Field, North Sea

    Ravn is a marginal oil field located in license 5/06 in the Danish sector of the North Sea. Covering an area of 333km², the field lies in water depths of 157ft (48m) and is being developed by Wintershall Noordzee, who is also the operator.
