Description

Vibration damper 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 & 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.

Feature

FR-Y & FDB-Y Series Preformed Vibration Damper 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. FR Type Preformed Vibration Damper is commonly used to control vibration of overhead conductors and OPGW. The vibration damper has a length of steel messenger cable. Two metallic weights are attached to the ends of the messenger cable. The centered clamp, which is attached to the messenger cable, is used for installing the vibration damper onto the overhead conductor. The asymmetrical vibration damper is a multiresonance system with inherent damping. The vibration energy is dissipated through inter-strand friction of the messenger cable around the resonance frequencies of the vibration damper. By increasing the number of resonances of the damper using asymmetrical design and increasing the damping capacity of the messenger cable the vibration damper is effective in reducing vibration over a wide frequency or wind velocity range.
