Vibration Damper for OPGW Cable
★ Easy installation
★ Low installation cost
★ High construction efficiency and convenient acceptance
★ Safety and reliability
Vibration Damper for OPGW Cable with a special Turning Fork type can produce four kinds of resonance frequency which covering the OPGW cable vibration range well. The installation can attenuate vibration amplitude, form seldom stable vibration frequency and eliminate cable fatigue damage. So you will feel satisfaction at the result.
Main Material of Vibration Damper for OPGW cable:
Dampering weight—Hot dipped galvanized cast iron,
Messenger Wire—19 strand galvanized steel wires.
Application Guide Of Vibration Damper for OPGW cable:
1.Vibration Damper can not be directly installed on the OPGW cable.
2.Work out the Span Length, if it is followed the Helical Rods, then installed as usual (Installed on Armor Rods directly.). When the installation point of Vibration Damper is outside of the Armor Rods, that you should installed a unit of Vibration Damper matches a unit of Armor Rods more. The end of the Vibration Damper must be away from the end of the Helical Rods more than 70mm.Select the Catalog Number of Vibration Damper and Armor Rods.
3.The low frequency Vibration Damper of installed Vibration Damper is close to pole(tower).
4.Decide the quantity per span corresponding to cable stress, span length and topography.
The normal specification Of Vibration Damper for OPGW cable:
Span Length (m)
◆High construction efficiency and convenient acceptance
◆Low installation cost
◆Safety and reliability
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.
