Abstract：The non-linear differential equations of the iced transmission line galloping was derived according to Lagrange equation, and the transmission line installed masses or detuning pendulums was fixed at both ends. Method to calculate the critical wind velocity was proposed.The non-linear differential equations were solved by Runge-Kutta method to get the galloping response in time domain.A test transmission line was calculated and analyzed as an example.The results show that:The torsional galloping can cause lateral galloping when their vibration frequency is close to each other.The amplitude of galloping is relatively large when the wind velocity is in a certain range.The galloping amplitude changes with the conductor sag significantly and there exists the least favorable sag to cause the largest galloping amplitude.The method to prevent galloping by masses can reduce but can’t eliminate the amplitude of galloping.But the method to prevent galloping by detuning pendulums can eliminate galloping completely.
