Spiral Vibration Damper
The Spiral Vibration Damper is a motion control product used to dissipate aeolian vibration that may occur on cable spans. Using the recommended number of Spiral Vibration Dampers minimizes bending strain, protecting the cable from long-term fatigue due to aeolian vibration.
-
Not placement sensitive - can be installed anywhere on the cable away from other attachments
-
Helically-formed PVC-based rod makes impact with the cable to disrupt the aeolian vibration standing wave
-
Gripping section of the damper gently holds the cable, preventing damage from clamping forces
-
Effective over a broad range of frequencies
-
Easily installed by hand
-
Can be nested (subsetted), allowing easier installation
-
Proven through extensive field and laboratory testing
-
Thermal rating of 125ºC for continuous operation
-
Hi-Mass version provides the effectiveness of two standard SVDs
-
Recommended aeolian vibration solution for all cables 0.75" in diameter and below

Reports & Manuals
Standard - For use on: Bare Conductors, Shield Wires and OPGW
NOTES: (1) Up to three SVD's can be subset together in one location where the cable diameter is 0.461" and below. (2) On cables with diameters above 0.461", only two SVD's should be subset for optimal damping performance.
