The vibration damper is designed to reduce the vibration caused by the wind force. High voltage overhead lines have higher pole positions and larger span. Vibration will occur when conductors are subjected to wind force. When conductor vibrates, the working condition of conductor suspension is most unfavorable. Due to repeated vibration, the conductor will suffer fatigue damage due to periodic bending. When the overhead line is more than 120 meters away, the vibration damper is generally used to prevent vibration.

Vibration DamperVibration Damper


On the high voltage overhead line, a small hammer is often hung on the wires near the insulators. This small hammer is called the Vibration Damper, which is designed to reduce the wire caused by the wind to pull up the vibration. High voltage overhead lines have higher pole positions and larger span. Vibration will occur when conductors are subjected to wind force. When conductor vibrates, the working condition of conductor suspension is most unfavorable. Due to repeated vibration, the conductor will suffer fatigue damage due to periodic bending. When overhead lines are more than 120 meters away, vibration dampers are generally used to prevent earthquakes.

The Vibration Damper is made up of a heavy hammer of a certain quality, and has a high elastic and high strength zinc steel strand and wire clamp.
