Electric power fitting accessories 4D Turning Fork type stockbridge vibration dampers makes use of rotation and 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 concentration of the latter. It is of good slippage and antivibration performance as well as superior installation of preformed rods guarantee sustainable, stable and reliable holding strength between the performed rods and the conductors while its high efficient construction will be good for the convenient and reliable checkup.

Its inertia and spiral elasticity can make the damping component generate relative displacement on the conductor swing, consuming vibration energy by effecting viscous damping phenomenon. The more the conductor swings, the more vibration damper consumes energy. Its installation shall take priority on its antinode; as its resonant frequency matches with the vibration frequency of conductor, the energy vibration damper consumes will be up to its maximum value.





Protective fitting for decreasing Vibration amplitude and Grading shielding of Insulator string such as dampers spacers.Spacer damper clamps are aluminum alloy. Dampers are elastomer. The other parts are hot-dip galvanized steel.

4D Turning Fork type Spiral Vibration Damper has higher frequency coverage characteristics, 3Hz~ 150Hz, it has four vibration frequencies, can provide complete frequency protection and perfect feature performance.





Vibration damper clamp is aluminum alloy,hammpers are grey iron, the other parts are hot-dip galvanized steel
