摘要：

Aeolian vibration in multiconductor overhead-power transmission lines is usually controlled by one of two techniques, namely by a combination of rigid spacing elements and endpoint Stockbridge dampers, or suitably positioned spacer dampers. In this paper, a comparison based on theory and computation is provided. It is concluded, consistent with observations over many years, that both philosophies suffice when the conductors are moderately tensioned ACSRs (aluminium conductor steel reinforced). When the conductors are moderately/highly tensioned AAACs (all aluminium alloy conductors), neither philosophy is totally adequate. If the two philosophies are combined, good vibration control will result in many circumstances.
