Voith has won a contract from Chinese rolling stock manufacturer Changchun Railway Vehicles to supply electric drive systems for new trams in Shenyang, Liaoning Province, China.
Under the deal, Voith will equip the trams with traction inverters, traction motors and Supercap energy storage units that can run without catenary wires on route sections of up to 700m.
The new above-ground network will be used by a fleet of five-car trams built by Changchun Railway Vehicles.
The first traction units are scheduled to be delivered to the Chinese manufacturer in January 2013, while all components for a total of ten vehicles will be delivered by April 2013.
The order for the ten drive systems is the first tranche of a framework contract that covers the delivery of 50 drive systems.
Each tram will be equipped with two Voith DI1000-5AR traction inverters, four Supercap energy storage units and four traction motors, resulting in a maximum input power of 700kW.
During normal overhead-wire operation, the energy storage units will be used to maximise energy efficiency and during this process, braking energy will be stored and made available to the traction system when the trams start, according to Voith.
In February 2012, China CNR Corporation started construction of the 65km five-line tram network from the Olympic Sports Centre in Shenyang under a RMB4.86bn ($767m) contract awarded by Shenyang municipality in December 2011.
The new tram network will link Taoxian Airport, Shenyang South high speed rail station, National Games Village and Olympic Sports Centre.
Under the deal, CNR will also provide an initial 20 low-floor trams.
The trams are scheduled to enter official passenger service from June 2013 in Shenyang, 40 years after the city's previous municipal tram system was shut down.
