We design, build, renew and maintain complete power supply systems for railways and urban transports, whether tramways, trolleybuses or metros.

Our systems range from High Voltage solutions – conventional air-insulated and gas-insulated armoured solutions – to Medium Voltage and modular solutions in prefabricated containers:

  • Air-insulated conventional HV substations

  • Gas-insulated HV traction substations

  • MV/LV traction substations, either conventional or in prefabricated containers

  • MV/LV transformer stations

We design customized solutions and we schedule interventions by stages, in order to limit the downtime of the system:

  • Partial or total renewals of existing HV/MT and MV/LV traction substations

  • Partial or total renewals of existing MV/LV transformer stations
