Contact wire de-icing
Train, tram and trolleybus
The ice formation of the overhead contact lines during the winter months is a problem for many transport services. The reduced conductivity can produce electric arcs which may lead to burning out of the contact wire and collect strip. Very thick ice can stop the current flow completely so that no traffic can occur. In either case costs can be substantial.
plays a decisive role in the proper functioning of the switches!
Switch lubrication is manual work. Since the labor costs for the application of the lubricant are in most cases considerably higher than the costs of the lubricant, long re-lubrication intervals are one of the most important requirements placed upon the lubricant.
