Made of weather-resistant, non-corrosive plastic, these dampers have a large, helically-formed damping section sized for the ADSS cable. A smaller gripping section gently grips the ADSS cable. Each damper is marked with the conductor range and color coded to indicate the cable diameter size range. Line design, temperature, tension, wind flow exposure and history of vibration on similar construction in the location are factors to consider when determining the amount of protection required. Installation can be on both sides of the support location—at least one hand-width from the ends of Armor Rods or cable hardware. Depending on the customer's specific conditions, AFL recommends the AVD Spiral Vibration Damper for ADSS cable in accordance with the recommended application chart.

Damper Recommendations for Placement Damper Recommendation applies for specified AFL dampers only. If alternative type or different manufacturer dampers are applied instead, it is possible that damage will occur on the conductor and/or the accessories. Symbol Designation 2/s = 2 dampers per span, 1 on each end of the span 4/s = 2 dampers in tandem on each end of the span 6/s = 3 dampers in tandem on each end of the span 8/s = 3 dampers in tandem + 1 damper on each end of the span 10/s = 3 dampers in tandem + 2 dampers in tandem on each end of the span 12/s = 3 dampers in tandem + 3 dampers in tandem on each end of the span 16/s = 3 dampers in tandem + 3 dampers in tandem + 2 dampers in tandem on each end of the span 18/s = 3 dampers in tandem + 3 dampers in tandem + 3 dampers in tandem on each end of the span 20/s = 4 dampers in tandem + 3 dampers in tandem + 3 dampers in tandem on each end of the span Placement and Spacing 1. AVD shall be placed approximately 5 inches away from any line hardware (suspension, deadend, armor rods, other SVDs, etc.). 2. AVDs can be nestled in tandem for up to three units to prevent the units from interfering with each other. 3. AVDs shall be applied to bare cable only to ensure proper performance.
