Current Collector Devices (CCD)
Current collector devices are used by metro systems to collect the energy from a third rail to power the Electrical Multiple Unit installed in the trailers.
3rd rail current collector system
Our comprehensive range of CCDs for metro systems is designed for all kind of configurations:
- Regular steel wheel metro trains
- Pneumatic wheel metro trains
- Monorail train
- Driverless metro trains
3rd rail current collector shoe (CCD shoe)
Mersen provides third rail shoes manufactured from carbon and metalized carbon materials:
- Specific designs (with metal end pieces, soldered, cast, EcoDesign)
- Plain carbon and metal impregnated grades
- Redesign, engineering, standardization
Mersen's EcoDesign 3rd rail shoe was awarded the Innovation Trophy at the SIFER 2013 railway show.
Mersen offers a variety of carbon and metalized carbon collector strips for overhead pantograph applications. Our extensive material grade selection and carbon and metal carrier designs include:
