FD Series Vibration Damper pole accessories

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.

Preformed Overhead FD-L Type Vibration Damper

The damper consists of a certain mass of heavy hammer, high elastic and high-strength galvanized steel lines and clamps. The anti vibration performance of the damper is related to the effective working frequency range of the damper.

When the conductor vibrates, the relative motion of the damper on the conductor absorbs the vibration energy of the conductor, thus reducing and eliminating the vibration of the conductor. All kinds of damper have certain natural frequency according to different structure, weight and geometric size.

Galvanizing

• The flat cross arm brace shall be hot dipped galvanized after fabrication in accordance with IS: 2629-1985 or any revision thereof or other equivalent national or international standard provided that ensure at least equal or better quality to the standard mentioned above will also be acceptable.

Tests

2.1 Apart from the tests indicated herein in the referenced standards, the flat cross arm brace shall undergo following tests:

- Visual Inspection;

- Verification of Dimensions;
