Essential to the smooth running of lines, overhead line works involve installing, maintaining and repairing all the components that supply trains with electricity.
Visible to everyone, yet little-known, catenaries are the collection systems that carry electricity to trains and trams. These sets of support cables are supplied by rectifier stations that transform the industrial current into a current adapted to each type of train.
Located throughout France, ETF’s catenary teams are made up of specialists responsible for building, monitoring, maintaining and modernising the equipment on the overhead power lines (1,500 and 25,000 volts) that supply trains. These missions are particularly complex and require the full commitment of the intervention teams.
The ETF Catenaries branch has a well-established in-house design office in France, which is a major asset in the planning and implementation of our projects. This highly structured design office operates in both the design and execution phases, offering significant added value. Thanks to this organisation, we are able to guarantee exceptional responsiveness in completing our operations within the desired timeframes.
