摘      要：Based on several typical severe ice accidents that occurred in China, this paper summarizes and analyzes the characteristics and causes for severe ice accidents. The results show that the ice accidents occurring in China have such characteristics as long duration, high frequency of occurrences, large coverage area and enormous loss to the national economy, etc. Drastic deterioration of mechanical property and electric property resulting from severe icing is the major cause of ice accidents. Besides, this paper summarizes the preventive measures for transmission lines in case of severe ice accidents.
