Systems for Combating Ice on Overhead Wires

Cold temperatures and atmospheric moisture can cause ice to form on overhead wires in winter, which is a problem that electrically operated railways must take seriously. Ice on contact wires reduces the amount of current that a vehicle is able to pick up, and in extreme situations it won't be able to pick up any current at all. The consequences of this are the formation of electric arcs, mechanical wear on the contact elements, and/or immobilization of train operations. With these issues in mind, this article looks at a new product, ProFil, for keeping overhead wires ice free.
