What is Spiral Vibration Damper

A spiral vibration damper is a device used to lengthen the cable line’s service life. It is also known as a Stockbridge damper or an SVD. Spiral vibration damper helps to mitigate the effects of aeolian vibration. This is from wind-induced oscillations in the conductors which can lead to failures. The SVD consist of two masses connected to the conductor by means of helical springs. The masses position equidistant from the point of attachment to the conductor. They also have designs to oscillate out of phase with natural frequency of the conductor system. using spiral vibration ensures the structural integrity and longevity of the system. This is especially in areas prone to high winds or other environmental factors. Spiral vibration dampers are essential to maintain the reliability of the electrical grid.
