THE EFFECT OF SPACERS IN REDUCING CONDUCTOR MOTION

, , and .
(1977)

Abstract

Bundled conductor systems are affected _by a~lian vibration, subconductor oscillation, and galloping. Field experience shows that bundles with spacers, when compared to single conductors in the same environment, will have a marked reduction of aeolian vibration activity, but an increase in the severity of galloping. If the aeolian vibration level on a bundled line requires dampers, dampers on one end of the span will protect the opposite support as in the case of a single conductor. For reduction of subconductor oscillation, the arrangement and length of the subspans are more important than the damping capability of the spacer itself.
