Catenary Heating Systems

Catenary systems provide traction power in many types of passenger transit networks, including. In cold-weather regions, ice will often pose a challenge to rail operators throughout the winter months. Even in warmer climates, ice buildup from freezing rain can cause serious problems for railroads — especially the accumulation of ice on overhead lines. Ice buildup on contact wires will interrupt the electrical energy transmission to the train and add weight that increases tension on the wires, placing the entire infrastructure at risk for failure. Besides the obvious risks ice poses to safety, fixing damage caused by ice on catenary systems can be extremely costly. This is why protecting overhead lines from ice buildup is necessary in any region where temperatures are cold enough to produce freezing rain. Inaddition to proven solutions for melting snow and ice on tracks, nVent provides a state-of-the-art system for keeping overhead contact wires free from ice.



The nVent RAYCHEM CATHeat brings advanced  heat trace cable technology to provide robust ice-melting power to overhead contact wires.
