In order to simulate rime and glaze icing conditions， three sets of rigid models with different ice thicknesses of crescent-shaped iced conductors with smooth and rough ice surface are designed and tested in the wind tunnel by high frequency balance. The relationship and difference in aerodynamic characteristics， wind-induced swing response and galloping stability are analyzed. Test results show that the drag coefficient of the iced conductor with rough ice surface is slightly larger than that with smooth ice surface， and the lift coefficient-attack angle curve and torsion coefficient-attack angle curve do not have sharp peaks. Under the same ice thickness and ice shape， the galloping stability of the iced conductor with smooth ice surface formed by glaze is worse than that with rough ice surface formed by rime and mixed rime. The wind-induced swing angle of iced conductor with rough ice surface is larger than that with smooth ice surface under the same wind velocity and line conditions， so that rime icing is worse than glaze icing for wind-induced swing of iced conductor.
