HEATING OF OVERHEAD CONTACT WIRES IN ELECTRIC RAILROAD SYSTEMS

FAHRDRAHTERWAERMUNG BEIM ELEKTRISCHEN ZUGBETRIEB

An analysis is made of the temperature rise caused by the alternating currents of the electric locomotives. The temperature variations with respect to both time and distance are considered. The analysis considers the thermal response in case of one-sided and two-sided power supply of the contact wire, while one or several electric locomotives travel on the line. The basic process associated with heating up of a wire due to a constant current is clarified.
