 Electrical cable accessories absorber mounting 

absorber mounting   for ADSS/OPGW cables, with tuning fork structure of Damper Weight, is validated by China Electric Power Research Institute that there are four frequency between 5~150HZ, and its vibration range is wider than FG Damper or FD Damper. 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:

1. Vibration Damper 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. 

The normal specification is as follows:
