A Single-Degree-of-Freedom Damper for Overhead Conductors

Aeolian vibration causes resonance motion of undamped conductors and eventually leads to fatigue failures. These failures occur at points of mechanical stress concentration caused by ties, clamps, and other hardware attached to the conductor. This paper describes a completely new concept in a damper designed specifically for suppressing conductor vibrations. The damper, based upon sound theoretical principles, has been tested in various laboratories and at field installations throughout the United States on telephone, distribution, and transmission conductors.
