VORTX™ Vibration Damper
The VORTX Vibration Damper responds to wind-induced line vibration that is characterized by high frequency, low amplitude motion commonly known as aeolian vibration. The large and small weights of the VORTX damper can achieve greater power dissipation and frequency response performance than “symmetrical weight” Stockbridge damper designs. Wider frequency coverage translates into better protection as energy is more effectively dissipated over the entire range of cable frequencies.
VORTX Damper Placement Software
-
Extruded aluminum alloy contoured clamp offers a “precision” fit to evenly capture the cable and uniformly distribute pressure along the surface of the cable
-
Meets IEC standard requirements
-
Precision-manufactured galvanized steel messenger strand efficiently dissipates vibration energy
-
Open, galvanized ductile iron weights do not enclose the messenger, reducing the possibility of corrosion.
-
Damper can be ordered with a breakaway bolt that has a bolt head designed to shear off when the bolt is tightened to the proper torque
-
Number and placement of dampers in each span is determined by a proprietary, internally-developed computer program that utilizes the results of ongoing field and laboratory research
-
VORTX Dampers are tested in accordance with IEC 61897: Overhead Lines – Requirements and Tests for Stockbridge Type Aeolian Vibration Dampers
