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. SVD shall be placed approximately 5 inches away from any line hardware (suspension, deadend, armor rods, other SVDs, etc.).
2. SVDs can be nestled in tandem for up to two units to prevent the units from interfering with each other.
3. SVDs shall be applied to bare cable only to ensure proper performance.
