About us

Our mission: create and implement durable innovative solutions to modernize power lines worldwide

Since 1987, Epsilon is a pioneer and world leader in high performance composite materials thanks to the pultrusion process. This highly efficient technology, combined with the extraordinary properties of carbon fibers makes the perfect solution to manufacture strong durable cores for High Temperature Low Sag (HTLS) conductors.
This new generation of smart conductors is successfully being used worldwide to increase ampacity, reduce sag and electrical losses.
Epsilon Cable is at the forefront of this grid modernization, with a proven track record of several thousands of kilometers of power lines installed worldwide in the past decades.

With its R&D center and Pultrusion facilities in France, Epsilon is ISO 9001 certified and supplies the most demanding cable manufacturers to help them achieve their ambitious performance & cost targets on conductors projects.

Epsilon Cable also offers HVCRC® conductors, accessories and support to utilities looking to improve their transmission and distribution lines.

Our history

1987
Creation of Epsilon Composite by Stéphane LULL, in the composite workshop of his father, Paul LULL.
1987
1988
First carbon fiber composite rods project in the electrical sector, for French electrical company EDF.
1988
1992
1st aerospace contract: structural profiles for military aircrafts for the Swedish manufacturer Saab. In the following years, Epsilon will become Tier-1 supplier for Eurocopter Super Puma transport helicopters, Airbus commercial jetliners and Thales space satellites.
1992
1994
1st success in civil engineering. Epsilon will then develop a complete range of carbon fiber products to reinforce bridges and buildings, and become one of the world leading manufacturers of carbon fiber structural reinforcements for civil engineering.
1994
1999
First composite profiles for submarine applications (deep offshore oil extraction).
1999
2003
Carbon fiber rods for PetroChina, manufactured in pultrusion and incorporating metal end-fittings for onshore oil extraction.
2003
2007
Development of the Carboglulam sparcap technology. The high performance yet cost-efficient technology was patented worldwide and soon adopted and qualified by Vestas and other major wind turbine manufacturers to manufacture giant windblades reinforced with carbon fiber pultruded profiles.
2007
2008
Submarine power umbilical cables for the Chinook Cascade deep offshore oil extraction project (Gulf of Mexico), with Aker. See project study for more details on this record breaking project.
2008
2011
First overhead line project in Australia, with Nexans LoSag technology, using Epsilon composite pultruded cores. See project study for more details...
2011
2011
First industrial production of pultruded composite rods with integrated optical fibers, for an oil & gas cable application.
2011
2012
Creation of Epsilon Training, our internal training center, certified by the French Education Minister. Every year, our apprentices and future employees are trained by our 2 full time instructors and 13 tutors on Epsilon's main skills such as pultrusion, non destructive testing, maintenance...
2012
2012
First HVCRC® conductor project in Kazakhstan. Learn more about this project here.
2012
2013
1st high voltage cables reinforced with a carbon composite core installed by RTE in France, using Nexans Losag conductors made with Epsilon composite pultruded cores. See project study for more details...
2013
2013
Qualification by the LiftInstitute of Epsilon carbon fiber pultruded rods for Kone Ultrarope® durable and eco-efficient elevator cables. This qualification opened the way to many record breaking projects worldwide, culminating with the elevators of Zun Tower, Beijing's tallest tower (528m), for which Epsilon manufactured more than 500km of composite profiles.
2013
2014
HVCRC® pilot line by Korean utility KEPCO, conducted on a 154kV commercial line in Seogochang. See project study for more details...
2014
2015
First wave of major HVCRC® project across Asia, America and Africa, reaching the milestone of 1000 km of HVCRC® installed. See project studies for more details on some of those projects.
2015
2017
ASTM B987 qualification for HVCRC®, which becomes the second technology worldwide to be qualified according to this international standard covering composite cores for high voltage conductors.
2017
2017
First 500kV HVCRC® project, for a double circuit line in Indonesia. See project study for more details...
2017
2017
Construction of a new dedicated carbon fiber pultrusion factory with a production capacity of 10 000 km of composite rods per year, the largest in the world at the time.
2017
2018
Epsilon wins patent conflict against CTC Global, promoter of ACCC®, who sued Epsilon and threatened its partners in an attempt to stop the production of HVCRC®. CTC Global patent EP1506085 is revoked (decision confirmed later in appeal) and CTC Global's claims are dismissed in court, confirming the lawfulness of Epsilon activities.

2018
2020
First wave of HVCRC® projects in Vietnam for EVN, with more than 1 000km of conductors reinforced with carbon fibers. See project studies for more details on some of those projects.
2020
2022
New milestone reached: 3 000 km of our composite core conductors electrified worldwide (including HVCRC® and 100% carbon fiber solutions from our partners).
2022
2022
