PLP Spiral Vibration Dampers

Aeolian Vibration is a high frequency, low-amplitude vibration initiated by laminar wind over the cable.  It can lead to detrimental effects on the overhead cable such as fatigue, wear, and even failure of the cables.  Aeolian vibration sometimes cannot be seen when looking at cable because of the low amplitude of the vibration but can be felt when touching the pole or a humming can even be heard.

PLP Spiral Vibration Dampers – An Innovative Solution

PLP Spiral Vibration Dampers impact the wire, disrupt the vibration created by the wind, and are effective over a broad frequency range. SVDs were developed by PLP following numerous vibration studies and extensive laboratory research and testing.

Spiral Vibration Dampers are made from a solid thermoplastic material, specifically formulated to withstand corrosive environments and UV. SVDs install easily, have no concentrated mass. PLP SVDs are specifically designed to minimize abrasion and fatigue to conductor and strand from wind-induced vibration. SVDs are suitable for use on conductors, strand, overhead shield wires, and OPGW cables measuring 0.76" outside diameter or smaller.
