Based on a numerical method calculating electromagnetic force between conductors, a finite element to determine the electromagnetic force during galloping simulation of twin bundle conductor lines is incorporated into ABAQUS software by means of the user-defined subroutine. The numerical method, which is verified with a numerical example, is employed to simulate galloping of twin bundle conductor lines with different span lengths and analyze the effect of electromagnetic force on their galloping characteristics. It is reflected by the numerical results that the effect of electromagnetic force on galloping of shorter span line is very small, however, the effect on that of longer span line increases with the electric current intensity. Therefore, it is necessary to take into account the effect of electromagnetic force while investigating galloping of bundle conductor transmission lines with longer span.
