Abstract: The influence of the temperature on the galloping characteristics of iced conductor was often neglected in related studies. In this paper, the galloping governing equation with consideration of the temperature effect is derived. Based on the catenary method and the thermal stress theory, the partial differential galloping equation of iced conductor is derived, then the partial differential equation is transformed into the ordinary differential equation by Galerkin method. The aerodynamic load model is established and the aerodynamic loads are introduced into the galloping equation. Then the displacement response of the iced conductor is obtained by the multiple scale method. Finally, a parameter analysis and a numerical example analysis are carried out. The results show that the temperature has a significant effect on the in-plane and out-of-plane frequencies of the iced conductor, and also has a certain influence on the galloping amplitude of the iced conductor. It can be seen that the influence of the temperature on the galloping characteristics of the iced conductors must be considered when studying the galloping characteristics of the iced conductor.
