Engineering guidelines relating to fatigue endurance capability of conductor/clamp systems

Conductor fatigue most often occurs at suspension clamps. The design tools presently available for the prediction of aeolian vibration amplitudes, the in-situ measurements of conductor vibration and the determination of the fatigue endurance of a conductor clamp system are presented. Important limitations of the present design tools for the determination of the fatigue endurance of a system and the prediction of aeolian vibration amplitudes are discussed.
