Vibration dampers is used to effectively reduce the level of aeolian vibrations on OPGW cables. It responds to wind induced line vibrations that is characterized by high frequency, low amplitude motion.
The second damper can be used for OPGW tension tower vibration dampers if necessary. Tension assembly is used for OPGW cable route's fixing and anchor shackling. Usually be installed on the terminal tower, tight tension tower and intersection angle tower.
