A Trolley Wire De-Icing System

This paper presents a dedicated system for de-icing trolley wires. The proposed issue is appropriately under the protection of intellectual property solving as described in patent no.B1 230665 PL Patent Office Republic Poland. In solution presented herein, achieved mainly by electrodynamic force excitation and secondarily result heating. Because ice removed primarily through vibrations, it avoids large consumption electricity associated with high specific heat water. More importantly, operation nearly simultaneously applied to total distance power grid between two substations. For this reason, requires less time apply than heating, mechanical, or chemical methods.
