CCD for Tramway Wireless

Static contact

Tramway technology is being more and more used in the development of urban mass transportation projects. The regular Tramway technology uses an energy collection based on a pantograph and catenary but it also exists an energy collection which doesn’t need catenary, the wireless technology. Two technologies enables a current collection from the floor in a dynamic or a static way. There are numerous advantages of these technologies, some being: - Aesthetic when the Tramway is next to classified buildings, monuments or historical city centers. The wireless technology will not disfigure the visual environement - For the security of the firefighters while intervention next to the catenary grid and for the safety of the people doing the maintenance of road public lightning - Finally to enable extra-large dimensions for road transports. Mersen innovate and is the first company to propose two different Current Collector technologies wireless (static and dynamic). The wireless static technology is a Current Collector operating a shoe in contact with a source under the tramway to re-fuel the batteries during Tramway dwelling time. At each stop the shoe powered by an electronic system is moved down to be in contact with the electrical source. During the 20 seconds a high DC current is re-fueling the Tramway batteries to enable it to go to the next station. Shoe is then moved up and the Tramway can reach the next station. Since 2013 eighteen trains are using this proven technologies in the world and 21 additional will come very soon. References Nice (FR), Luxembourg (LX), Zaragoza (ES)
