Innovative solutions for mass transit and railway

Tramwave is an innovative catenary-free power supply solution designed and patented by Ansaldo STS that doesn’t constraint urban vehicular and pedestrian circulation. The contact line is composed of consecutive modules of 3 to 5 m long, embedded in the ground in the middle between the rails; each module is made by 50 cm long conductive steel plates (also called segments), that are insulated between each others and release energy only when the traction boogies are over them and the traction collectors are realised being in contact with them. A mandatory condition for the ground contact line to release power is the presence, on the segment, of the vehicle with the power collectors released, that activates the segments and pick up the current. The steel plates (segments) in contact with the power collectors are the only one energised; the rest of the contact line is not fed. The safety of people and vehicles is always guaranteed.
