Efficiency of anti-icing measures on railway power supply devices
Incoming article date: 14.08.2025The majority of electrified railways, as well as the routes of external power supply overhead lines, automatic block lines and longitudinal power supply lines, are located in areas with a sharply continental climate, where climatic conditions contribute to the possibility of ice formation. The article examines the effectiveness of anti-icing measures on power supply devices of electrified railways. The results of calculation of the anti-icing scheme during preventive heating of the contact network taking into account its homogeneity by equalizing current are presented. The success of application of preventive heating for the studied section is analyzed.
