Abstract	The aerodynamic coefficients of each subconductor in an iced quad bundle conductor covered with crescent-shaped and sector-shaped cross-sections were determined by the wind tunnel test. A cable element with torsional degree of freedom used to simulate the iced conductor is obtained in ABAQUS software by releasing the two bending degrees of freedom and setting the material to be incompressible. The aerodynamic loads varying with the angle of attack during moving of the bundle conductor are applied on the cable elements used to discretize the iced subconductors through the user-defined element subroutine UEL in ABAQUS. The numerical method verified by two examples is employed to investigate galloping of iced quad bundle conductors at different wind speed, initial angle of attack, ice thickness, ice shape, and span length, and the results reflect the influences of these parameters on the galloping behavior of the quad bundle conductor, which is important for the development of anti-galloping technology.
