In order to understand the effect of tension on the wind-induced vibration of transmission line-Bate damping line system

the energy balance method is used to analyze the wind-induced vibration characteristics of the system.Combining with IEEE transmission line vibration test guide

a test model of transmission lineBate damping line system is designed.The characteristics of transmission line under breeze vibration before and after installing the Bate damping line are analyzed

and the influence of tension variation on the anti-vibration effect of long-span transmission line is studied.The results show that:（1）The amplitude of breeze vibration of the conducting wire can be effectively reduced by the Bate damping line

but the damping effect of the single lace Bate damping line is limited.The long-span transmission line needs the combination of multiple lace Bate damping lines to prevent vibration.（2）Tension forces can change the vibration resistance characteristics of transmission lines

and has a great influence on its anti-vibration effect.（3）When the tension force of the conducting wire increases from 18% RTS to 25% RTS

the displacement increases first and then decreases for the bare conducting wire without a Bate damping line.But for the transmission lineBate damping line system

when the tension force increases from 18% RTS to 22% RTS

the variation trend of vibration displacement is not consistent under different excitation frequency bands.When the tension force increases to 25% RTS

the vibration displacement decreases

consistent with the bare conducting wire without the Bate damping line.
