Clemessy to carry out electrical works on the Lyon underground

11.07.2017

Sytral, the Public Transport Authority responsible for maintaining the Lyon underground, has chosen Clemessy and the Tabelec® department to carry out electrical works on lines A, B and C.

The Clemessy Lyon office will be in charge of most of the engineering and site work, whereas Tabelec® will carry out the engineering concerning the main low-voltage switchboards (MLVS) and manufacturing them.

The teams involved will have to replace the 24 main LV boards which were put into service during the construction of the underground in 1975. Each of these switchboards currently supplies power to one of the 24 underground stations spread out along lines A, B and C. They will gradually be replaced by new, identical equipment, in order to provide lighting in each station and ensure the escalators and the video surveillance system operate properly, etc.

The 24 underground stations will have to remain open during the works so that no inconvenience is caused, allowing the network operator to continue providing service for its users. The teams working on this project will have to install six main LV boards each year between 2017 and 2020, ensuring that all of them are replaced in 4 years.
