Abstract: Wind, ice and combined ice-wind loads must be assessed during design and/or reconstruction of Overhead Transmission Lines (OHL). According to Russian standards, climatic loads must be assessed using climatic regional maps. Such maps are based on huge massive of meteorological observation data. Design climatic loads are calculated depending on desired reliability level of OHL. This article shows Russian approach for design loads assessment.
