De-icing device for catenary wires

In the case of fixed-rail vehicles the formation of ice on catenary wires in the winter months limits current absorption, which often makes it impossible to ensure the scheduled transport. The catenary wire de-icing device of the German STEMMAN - TECHNIK GmbH company uses glycerine as lubricant, which it stores in tanks located in the interior of the vehicle, from which it is delivered through pipes, using compressed air, to the lubricating unit mounted next to the carbon rubbing strip of the collector. De-icing is effective for 2-3 days.

We have developed this device further, and it is successfully used on the Budapest Cog-wheel Railway.
