Abstract :
The main purpose of this paper is to calculate the behaviors of interphase spacers to reduce the amplitude of galloping in conductors. In simulation, three phases and iced-single/two-bundles conductors with/without spacers are considered in viewpoint of standard cases. The implicit/explicit finite element methods are used to calculate the transient response with geometric nonlinear behavior. ANSYS/LS-DYNA program is also applied. Calculation results can be used to predict the positions to insert the interphase spacers between conductors.
