Plenty Vibration Dampers have been installed on ADSS cables.
absorber mounting Material:
Damper weight—Hot dip galvanized cast iron
Messenger Wire—19 strand galvanized steel wires
Clamp—Aluminium Alloy
Amour Rods—Aluminium Alloy.
absorber Application Guide:
- Vibration Damper can’t be directly installed on the OPGW cables, installed with Helical Rods.
- 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.
- The big Damper Weight of low frequency is close to pole or tower.
- Confirm the quantity per span length according to cable strength, span length and topography.
The normal specification is as follows:
