VORTX Stockbridge Damper (VSD)
SKU: VSD-000For use on: AAC, ACSR, AAAC or SBC aluminium conductors.
- Extruded aluminum alloy contoured clamp offers a precision fit to evenly capture the cable and uniformly distribute pressure along its surface
- Meets IEC 61897 and IEEE 664 requirements for Stockbridge dampers
- Precision-manufactured galvanized steel messenger strand efficiently dissipates vibration energy
- Galvanized ductile iron weights
- Dampers can be ordered with a breakaway bolt head designed to shear off when the bolt is tightened to the proper torque value
- Number and placement of dampers in each span is determined by a proprietary, internally-developed online program that utilizes the results of ongoing field and laboratory research
- EHV VORTX Dampers are available for 500 kV applications
