The TramWave catenary-free electrification system developed by Ansaldo STS is to be deployed in China for the first time after the Italian company concluded a €26m contract with CNR Equipment Engineering, which will see the technology installed on a new light rail in Zhuhai, Guangdong province.
 
Ansaldo STS signed a strategic agreement last year licensing TramWave to a joint venture between the parent company of CNR Equipment Engineering and General Resources Company, Taiwan, allowing the system to be sold in China.
 
TramWave will be installed along the entire length of the 8.7km Zhuhai Line 1, making it the largest deployment of the technology to date.
 
TramWave uses a box embedded in the road surface containing a contact line that is only activated when an LRV passes overhead. A series of contact plates are fitted along the upper surface of the box at 50cm intervals, which feed power from a cable inside the box to the collector shoe fitted inside the vehicle bogie. The shoe is surrounded by an earthed safety ring, which operates whenever the LRV is drawing current from the modular boxes. The boxes also include a path for return currents, meaning the running rails do not need to be used for this purpose. Ansaldo STS says this means TramWave cancels the effects of stray currents, offering significant maintenance savings.
