| Abstract: | The severe storm is one of the most threatening natural disasters for transmission lines.The operation status of transmission lines under wind hazards throughout the world is reviewed,especially in China.The impact of catastrophic winds such as typhoon,downburst,and tornado on transmission lines is introduced,including collapse of transmission towers.Wind hazard events in recent years show that in order to enhance the wind resistance of transmission lines,it is urgent for China to carry out study and risk assessment of wind hazards for transmission lines and to improve the wind resistant design for transmission towers. |
