VORTX™ Vibration Damper and Protector Rods
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 dampers can achieve greater power dissipation and frequency response performance than "symmetrical weight" Stockbridge damper designs. Wider frequency coverage translates into better span protection as energy is more effectively dissipated over the entire range of natural frequencies.
VORTX Damper Placement Software
-
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
