CURRENT COLLECTOR DEVICE (CCD) SHOES Mersen offers a large range of CCD shoes for electrical current collection in urban networks. The diversity of products allows to find the most suitable solutions for each metro system. The use of carbon allows to reduce friction, and therefore protects the power rail and improves its lifetime. CHARACTERISTICS OF MERSEN CCD SHOES LINKED TO THE APPLICATION CHARACTERISTICS… ✓ Frequent stops ✓ Frequent acceleration and deceleration ✓ Multiple regenerative braking ✓ High dust exposure … MERSEN CCD SHOES SATISFY 4 MAJOR CRITERIA: ✓ Resistance to mechanical impact ✓ Ability to withstand high starting and stopping current loads ✓ Excellent sliding properties ✓ Non-destructive to the power rail CURRENT COLLECTION BY 3RD AND 4TH RAIL

CCD SHOE DESIGNS A CCD shoe consists of a carbon part mounted on a supporting carrier. The carrier's role is to protect the carbon collector from impacts, to resist deflection and to conduct the current. DESIGN WITH METAL END PIECES ✓ Assembly: metal end pieces ✓ Application: fitted to a new system to create a film, or to a rail in bad condition to clean its surface with the bronze contact DESIGN AS SOLDERED VERSION ✓ Assembly: clamped, soldered ✓ Application: all networks with or without ramps ✓ Available in different carbon widths and heights DESIGN AS CAST VERSION ✓ Assembly: carbon inserts...

MERSEN GRADES FOR CCD SHOES Bulk density GRADE Charpy resilience kJ/m² Plain carbon Metal graphite Indicative values Contact us to request our complete technical data sheets as well as our safety data sheets. METAL vs. CARBON SHOES Steel, cast-iron, copper or bronze shoes on third rail collection systems mechanically damage the rail due to their relatively large mass and high friction coefficient. Carbon has many advantages over metallic materials, and the benefits to user systems are numerous. As a consequence, more and more railway, 3rd and 4th rail, tramway and trolleybus systems have switched...
