Solutions for LV traction power

For power supply networks for catenary systems and overhead contact lines (OCL), including substations.

For securing the power supply to control and monitoring systems and ensuring high availability of the LV energy, we offer Uninterruptible Power Supplies (UPS or inverters) and DC rectifiers.

Our switchgear and protection solutions integrated in AC or DC protective enclosures are approved by the French rail network. For main lines, for example, they ensure protection of the batteries or auxiliary power supplies. For urban transport systems, we offer cable terminal disconnect switches (CTD), line isolation disconnect switches (LID), cleaning channel isolation disconnect switches (CCID), and emergency storage siding switches (ESS). Our energy measurement systems monitor the LV network parameters in real time, with communication gateways, data loggers and embedded web server.


These solutions can meet special requirements such as applications for outdoor use in severe weather conditions or with special fire-resistance features specifically for underground rail networks. Do not hesitate to contact us for more information.
