Description
Contact wire is shaped wire that comes into contact with the pantograph of the train. It provides power from the catenary line to the train. Contact wire is a key part of the catenary line (with dropper and messenger wires).
Thanks to continuous copper casting and contact wire drawing, we are able optimize contact wire properties for full control along the transformation process, from raw materials to the finished product.
Nexans provides standard contact wire solutions (ASTM or European products) as well as contact wires that meet specific needs. Feel free to contact us with your requirements. We are continuously developing contact wires with optimized properties.
Application
Contact wire for railway catenary line.
