Product description of damper:

when cable suffers form aeolian vibration, the hammerhead of the vibration damper hanging on the cable may vibrate freely along with the movement of cable to make the steel stranded wires on anti-vibration damper rub each other,convert the vibration energy passed on to the  anti-vibration damper to friction heat among steel standed wires and consume such heat energy, thereby effectively supperessing the aeolian vibration of cable and prolongthe life of cable.

Usage of FR Vibration Damper:

Protective hardware,mainly used to reduce the vibration amplitude of overhead power line conductors and lightning wires


 Application Guide damper:

1. FR Vibration Dampers can`t be directly installed on the OPGW cables, installed with Helical Rods. 
2. Calculate the installation distance, if it is within the Helical Rods, then installed as usual (Installed on Helical Rods directly). If the installation position of Vibration Damper is outside of the Helical Rods, you should install Helical Rods. The distance between the end of the Vibration Damper and Protection Rods must be more than 70mm.
3. The big Damper Weight of low frequency is close to pole or tower.
4. Confirm the quantity per span length according to cable strength, span length and topography.

5. Hardware Accessories Vibration Damper, Protective Fitting FR Vibration Damper
