Overview

when cable suffers form aeolian vibration, the hammerhead of the vibration damper hanging on the cable may vibrate freely along with the movement of cable to make the steel stranded wires on anti- vibration damper rub each other,convert the vibration energy passed on to the anti- vibration damper to friction heat among steel standed wires and consume such heat energy,thereby effectively supperessing the aeolian vibration of cable and prolong the life of cable.
