Railway Contact Wires Description
The contact wire is the primary conductor in the overhead line (OLE) system. Suspended from the catenary by catenary wires, it makes direct contact with the pantograph, transmitting power from the OLE to the train. The contact wire is designed with a specific shape to maintain a consistent and stable connection with the train’s pantograph.
