Spiral Vibration Dampers for OPGW

Made from high impact, UV resistant, polyvinyl chloride (PVC), they are noncorrosive and do not abrade the OPGW or require engineering calculations for positioning. Vibration dampers are designed to reduce cable vibration at tangent
supports and dead-end positions. The degree of protection needed on a specific line depends upon a number of factors such as line design, temperature, tension, exposure to the wind flow and vibration history on similar constructions in the
same area.
