1,Good eliminate vibration effect 2,Galvanized steel 3,Simple and reliable structure 4,GB/T 2336-2000 Damper technique

FR preformed vibration damper   is for the elimination of the natural vibration and eliminate the wind line caused resonance.

 In order to avoid and lighten the conductor’s vibration, we usually install some dampers around the suspension clamp. The damper will have a vertical motion when the conductor vibrates. As a result, it creates an asynchronous even reverse force to reduce the conductor amplitude even eliminate its vibration.

Parts

 Made up of hammer, steel strand, stranded aluminium conductor and bolt.

 Functions and Features

1,There are four resonance frequency, which can greatly cover the vibration of the ground wire reality frequency range.

2,Hammer and permanent suspension wire bonding, which can endure installation and maintenance operation conditions of the mechanical load.

3,The unique appearance design, no logged water and ice.

4,Vibration control by the hammer corona design can prevent the corona happen.

5,Convenient installation safety, no ground wire damage.
