High Stability Preformed Vibration Damper pole accessories

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.

Technical Parameters

Unit:mm

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.

The pre twisted damper uses the pre twisted wire as the connection structure of the vibration proof vertical clamp and the protected wire, so it has the advantages of convenient and quick installation of the pre twisted hardware, good grip strength for the wire (to avoid the loosening of the clamp caused by the thermal expansion and contraction), even grip strength without damage to the wire, no hidden danger of bolt loosening (maintenance free), good anti corona, energy saving (both the pre twisted wire and the clamp are made of aluminum alloy), and fatigue resistance Advantages such as superiority. It has been proved to be excellent and widely used in the power lines of developed countries in decades of operation.

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.
