Transformer-rectifier groups for traction supply
Traction power supply technologies belong to the most important areas in the transport infrastructure.
ABB provides solution for AC MV catenary supply as well as for DC supply traction systems. One of the key element of DC traction system (apart from switchgears and protection system) is transformer-rectifier unit.
ABB offers standard and customized transformer-rectifier units, diode or thyristor, which contain variety of options.
If energy recovery is needed, inverters are also available. ABB takes responsibility of whole supply system calculation, design, manufacturing and commissioning (if applicable) according to customer specification and network limitations.
