Spiral Vibration Damper

Recommended aeolian vibration solution for all cables 0.75" in diameter and below

huaneng Product Page

Hi-Mass version provides the effectiveness of two standard SVDs

Gripping section of the damper gently holds the cable, preventing damage from clamping forces

Helically-formed PVC-based rod makes impact with the cable to disrupt the aeolian vibration standing wave

Not placement sensitive - can be installed anywhere on the cable away from other attachments

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.
