Clamp Type Vibration Damper for ADSS/OPGW optical cable, 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.
Material:
Damper weight—Hot dip galvanized cast iron
Messenger Wire—19 strand galvanized steel wires
Clamp—Aluminium Alloy
Helical Rods—Aluminium Alloy.
The dampers are used to absorb the cable vibrations , The number of dampers is determined by the environmental conditions, the distance between towers, the type of OPGW cable and the installation parameters.
