Conductor galloping phenomena on overhead transmission lines are of great danger to the security of service of electrical power system.Based on several typical iced conductor galloping phenomena occurring in China

this paper summarizes and analyzes the characteristics

reasons and preventing techniques of conductor galloping.The results show that the galloping phenomena occurring in China have such characteristics as high strength

larger and larger coverage area

etc.The formation of conductor galloping mostly relies on icing

wind as well as configuration and parameters of transmission lines.The harm resulting from conductor galloping can be effectively avoided

resisted or restrained if some measures are taken. Galloping-avoidable measure is to choose appropriate line path as far as possible to avoid the microclimate and micro-terrain which possess special conditions of galloping.Galloping-resistable measure is to enhance the mechanical and electric strength of transmission lines so as to ensure that conductors and other components will not be damaged when conductor galloping occurs.Galloping-restrainable measures is to install anti-galloping devices on transmission lines so as to destroy the formative conditions of galloping phenomena

restrain the amplitude of galloping and ensure the security of service of transmission lines.
