CATPRO - Contact wire wear measurement system

The CATPRO Contact Wire Wear Measurement System is an advanced optical monitoring solution designed to continuously measure overhead contact wire wear during live railway operations. Installed directly on the pantograph, CATPRO operates safely even with traction voltage switched on, delivering precise, real-time data for predictive maintenance. Using laser and 3D stereo camera technology, the system accurately measures remaining cross-sectional area and torsion of the contact wire, helping operators forecast maintenance needs and prevent failures. With minimal installation effort, galvanic isolation, and seamless data integration, CATPRO significantly reduces manual inspections while improving overhead line performance, safety, and asset lifespan.
