The aerodynamic coefficients of the iced crescent shape conductor models varying with angle of wind attack were obtained by wind tunnel test. The aerodynamic characteristics of iced eight bundled conductor may be more complicated due to the wake interference around the sub-conductors. Based on the aerodynamic coefficients and ABAQUS software, galloping behavior, such as dynamic responses, galloping orbits, frequencies, vibration modes and amplitudes of typical iced eight bundle conductor transmission lines in the cases of different span lengths, initial tensions in sub-conductors, wind velocities and angles of wind attack is studied. These results provide galloping behavior recognitions of iced eight bundled conductors and development of anti-galloping technology.
