Description

FR type pole line hardware stockbridge vibration damper is used in high voltage transmission line to protect and decrease vibration amplitude of the conductor or cable.

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 concentration of the latter. It is of good slippage & antivibration performance as well as superior installation of preformed rods guarantee sustainable, stable & reliable holding strength between the performed rods & the conductors while its high efficient construction will be good for the convenient & reliable checkup.
Its inertia & 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.

Usage and characteristic

The damper is used to lessen fatigue damage of breeze to wire. So there must be reasonable weight and installation location. When dampers slip, this can harm wire more seriously.This kind of anit-slip hippocampus damper that produced by our company has special weight and reasonable shape design.
It can produce several resonance frequencies and it can also absorb vibration of variable frequencies effectively. The patent installation with pre-twisted armor rods can ensure large bond area and evenly-
distributed adhesive force so that there’s no stress concentration and the constant installation torque can be stayed.
Therefore, the product can not slip. This can avoid fatigue damage of wire effectively and lengthen service life of lin.
