RSSB2757 - T1161 Improvements to pantograph collector strips maintenance and to Automatic Dropping Device

This research focuses on: 1. Identification of cost-effective wear management strategies together with novel technological options for the collector strip. The collector strips (or carbon strips) in contact with the OLE contact wire are the key component for the transmission of electrical energy between OLE infrastructure and the train. When the train is in motion, the strips are subjected to abrasion, electrical damage and fatigue eventually reaching their electrical and mechanical engineering limits. Hence, they must be regularly inspected and renewed (every 10-30 weeks ). 2. Improvements to the Automatic Dropping Device (ADD), a component of the pantograph. Closely allied to the…
