Vibration damper makes use of rotation & swing of the two-end hammer heads for generating friction damping force from the mutual slippage among the galvanized iron wire strands to consume the swinged energy. It is adopted preformed rod structure in which the holding strength between the installation of vibration damper to preformed rods and the conductors evenly spread the distance from 30 to 60cm on the length area, effectively protecting the conductor by avoiding the stress concentraton of the latter.
2.Characteristic
It adopts typical Hello's design. Frequency protection is distributed enough to the range of 6Hz -150Hz wide frequency zone. And in this range, there are four resonance frequencies.
3.Function of vibration
Length of span, tensile magnitude, wind speed, wind direction, landform, and the structure and size of the cable.
