Through changing of the conductor configuration andnarrowing wire phase spacing,500kV power transmission lines improve the natural power and compress transmission lines corridor, meanwhile, increase the difficulty for observation and prevention. Through the observation wave amplitude,frequency and the calculation of critical wind speed, we must adopt measures to restrain dancing so that can effectively avoid the harm of galloping of iced conductor.
