Abstract：Anti-galloping design of interphase spacers in three-phase conductor lines with triangle arrangement is numerically studied. Based on the galloping characteristics of transmission line with 300m-span under wind load, four installation schemes of interphase spacers are presented and their anti-galloping efficiencies are numerically investigated. It is suggested that both vertical and horizontal vibration modes during galloping have to be taken into account in the installation design of interphase spacers, based on which anti-galloping schemes of interphase spacers for the transmission lines with 400m-span and 500m-span are designed and their anti-galloping efficiencies are further numerically proved.
