For profoundly understanding the influence of wind speed on the dynamic tension of iced bundle conductor, the influence of wind speed on galloping rules, tension variation, and amplitude of quad-bundle conductor under number 4-8 wind were investigated by nonlinear finite element analysis and theoretical analysis methods. The results shows that wind speed have great influence on galloping amplitude and dynamic tension. Galloping amplitude will rapidly increase with the increase of the wind speed at the beginning, but when the wind speed increased to a certain extent, the increase of galloping amplitude in plane and dynamic tension will become not obviously, and the maximum dynamic tension approximately doubles the static tension. The galloping and tension variation rules of bundle conductor were changed from stability periodic motion to complicated quasi periodic motion.
