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.
