One of the largest climatic chambers in Europe and a set of tests facilities for ageing, natural or artificial pollution

200 m3 climatic chamber that is able to create an environment between -40°C and +60°C, ice tests, solar radiation or humidity.

675 m3 accelerated ageing room fed with 60 kV and 170 kV 50 Hz voltage generators. Performing combined cycles of rain, salt spray, heat (+50°C), humidity and solar radiation.

Martigues seashore test station with several testing areas and different voltage generators from 2.2 kV up to 245 kV. Severe natural marine and industrial pollution conditions, high levels of solar radiation and low rainfall.
