Spread over more than 40 ha, the laboratories have a large number of test facilities, in particular installations with exceptionnal characteristics:
Test stands for electrical endurance cycles on cables or accessories up to 600 kV, a climatic chamber with a volume of 1200m3, a permanent strong test hall up to 50 kA, A range of 400 kV line of 300 m.

The Laboratories perfom short-circuit, electrical and mechanical endurance tests, dielectric and climatic tests on equipment in the development phase, type acceptance, reception or investigation.
The laboratories are positionned as one of the major European testing laboratories, capable of carrying out tests according to current standards or according to specific programs requested by our customers.

By integrating them into a Research and Development department, the test teams participate in the realization of projects aimed in particular at understanding the ageing mechanisms of electrical equipment, optimizing the reliability of the networks, improving safety and to adapt the networks to energy transitions.
In order to carry out this task, the laboratories implement complex test plans that respect the actual conditions of installation and operation. The laboratories benefit if necessary from the expertise of 2000 R&D researchers from EDF.
