Preformed Line Products Hi Mass Spiral Vibration Damper (HMSVD), White - .327” - .461” (PLP 5050201) - The Hi Mass Spiral Vibration Damper (HMSVD) features a damping section nearly twice the length of a standard SVD, offering the performance of two standard dampers in a single unit. This enhanced design reduces the number of installation points and minimizes components on the line.
Engineered to reduce Aeolian Vibration—high-frequency, low-amplitude oscillations caused by wind—the HMSVD is ideal for use on OPGW, conductors, and strand with an outside diameter under 0.75”. Unlike devices that guard against stress concentrations, abrasion, or arc-over burning, this damper is solely focused on vibration mitigation. Protection needs vary depending on factors like line design, tension, wind exposure, temperature, and vibration history in the area.
Features:
- Made of solid polyvinyl chloride, helical rod material is noncorrosive and has a surface hardness which does not abrade the strand
- For application-inspection, the gripping section should be installed approximately one hand’s width from the ends of hardware. Engineering calculations are not required for placement locations.
- Compatible with any down guy strand
PART TABLES
Standard - For use on: Bare Conductors, Shield Wires and OPGW
Explanatory Notes: (1) Up to three SVD's can be subset together in one location where the cable diameter is 0.461 in. and below. (2) On cables with diameters above 0.461 in., only two SVD's should be subset for optimal damping performance.
