Anti-vibration hammer is designed to reduce the vibration of the wire caused by the wind.High – voltage overhead line rod position is higher, the gear distance is larger, when the wire is acted by the wind, vibration will occur.When the conductor vibrates, the working condition at the suspension of the conductor is the most unfavorable.As a result of repeated vibration, the conductor will suffer fatigue failure due to periodic bending.When the overhead line gap is greater than 120 meters, vibration prevention hammer is generally used to prevent vibration.

Counter weight are gray iron Painted .The other parts are hot-dip galvanized steel.
