Our mission: design and implement advanced conductor 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 composite cores for advanced conductors, also known as type 4 High Temperature Low Sag conductors (or “HTLS conductors”). This new generation of smart conductors is successfully being used worldwide to increase the line ampacity, and to reduce line sag as well as electrical losses.
Epsilon Cable is at the forefront of this grid modernization, with a proven track record of several thousands of kilometers of conductors installed worldwide in the past 2 decades.
With its R&D center and Pultrusion facilities in France, Epsilon is ISO 9001 certified and supplies the most demanding cable manufacturers and EPCs to help them meet utilities’ ambitious performance & cost targets on reconductoring projects as well as new lines.
Epsilon Cable and its partners also developed the HVCRC® advanced conductor range, along with the necessary hardware. From line design to installation and maintenance, we provide our support and expertise to utilities looking to improve their transmission and distribution lines thanks to advanced conductors.
Based on continuous improvement and a constant striving for performance to satisfy our customers requirements, Epsilon’s Quality Management System is certified according to the ISO 9001 standard.
The health and safety of people and the respect for our environment are among our top priorities. Not only do we comply with strict health and safety regulations and best environmental practices, but we are also constantly thinking about ways to reduce our environmental footprint at all levels, as well as ways to reinforce our positive impacts on our environment.

1988
First carbon fiber composite rods project in the electrical sector, for French electrical company EDF.
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.
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.
1999
First composite profiles for subsea applications and deep offshore oil extraction with Technip, for oil majors Total and Petrobras.
2003
Carbon fiber rods for PetroChina, manufactured in pultrusion and incorporating metal end-fittings for onshore oil extraction.
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.
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.
2011
First overhead line project in Australia, with Nexans LoSag technology, using Epsilon composite pultruded cores. See project study for more details...
2011
First industrial production of pultruded composite rods with integrated optical fibers, for an oil & gas cable application.
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
First HVCRC® conductor project in Kazakhstan. Learn more about this project here.
2013
1st high voltage overhead line with a carbon composite core installed by RTE in France, using Nexans Losag conductors and Epsilon composite pultruded cores. See project study for more details.
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.
2014
HVCRC® pilot line by Korean utility KEPCO, conducted on a 154kV commercial line in Seogochang. See project study for more details...
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.
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
First 500kV HVCRC® project, for a double circuit line in Indonesia. See project study for more details...
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.
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. Read more about this topic here.
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.
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
First HVCRC® projects in Europe. After more than a decade of sucesses on other continents, the HVCRC® technology is increasingly selected by many European utilities for reconductoring projects, to support their electrification and energy transition.
2023
CORECHECK® is successfully deployed on the field for the first time. This innovative monitoring technology allows to assess the integrity of our composite cores at various stages of the project (before, during and after installation).
