Afterward, vibration equations of bundle conductors system which consider the effects of spacer dampers are derived(including transcendental function and plural), the vibration frequencies and modes of bundle conductors system are got by solving the transcendental eigenvalues of these equations. Then the amplitude ratio of each spacer dampers to sub-conductors are got, so bundle conductors can be exactly solved with the application of energy balance method as single-conductor.
