Contact Wire Thermal Scanning

Overhead catenaries can become overheated, expanding to such an extent that they almost touch the wagons. When overheated, contact wire starts to expand, looses tension and starts to sag. In the worst case, it gets wound up around the locomotive’s pantograph. The train stops and the line is blocked. Repairing overhead lines takes time and one can only imagine the consequences on busy lines at rush hour.

MERMEC Group Thermal Scan Monitoring System is an infrared imaging system designed to carry out the thermal image of the contact wire. The systems is rugged to stand in a housing outside a train wagon an it has an image frequency able to visualize the lines also at very high-speed. The systems measures in a range of 40°C to +500 C.
