Vibration damper and spiral vibration damper are both anti-vibration fittings, but these two anti-vibration fittings have some differences in appearance, material, and anti-vibration principle.In terms of appearance and material, vibration damper is composed of two hammers connected at both ends of a steel strand, and a wire clamp is fixed in the middle. The main materials are usually aluminum alloy, steel strand, gray cast iron and other metal materials.The spiral vibration damper is a spiral PVC round rod, the main materials are PVC and PE heating and extrusion molding.And the anti-vibration principles of these two products are different. vibration damper mainly uses the inertia of the hammer head to cause internal friction of the steel strand to consume the vibration energy of the overhead wire, while spiral vibration damper dissipates the vibration energy through the impact with the cable, so as to eliminate or reduce the vibration generated by the laminar flow wind when the cable is running, and protect the cable and fittings.
Advantages of spiral vibration damper:
1. spiral vibration damper can reduce the fatigue and damage caused by the vibration of the wire due to wind, protect the wire, insulator and fittings, and extend the service life of the line.
2. spiral vibration damper has a simple structure and relatively light weight. The installation process does not require complex tools. It can be quickly fixed to the wire and easy to install.
3. spiral vibration damper can work stably under a variety of meteorological conditions, has good adaptability to the environment, and can be applied to different types of wires and optical cables.
4. The material of spiral vibration damper is durable, not easy to damage, and does not require frequent maintenance in the later stage, which can reduce maintenance costs.
Installation of vibration damper:
Vibration damper needs to determine the installation quantity according to the line gear distance. There is no need to install the gear distance <100 meters. The 100-250 meter gear distance requires 2 at each end, the 250-400 meter gear distance requires 4 at each end, and the 400-800 meter gear distance requires 6 at each end.The specific installation methods of vibration damper include series type: the first branch is >500mm from the end of the preformed wire, and the subsequent intervals are arranged linearly at 120mm, and parallel type: multiple branches are stacked at a position >500mm from the end of the preformed wire, and the interval is ≤120mm. When installing, you need to keep the grip section close to the side of the tower, and the distance between the end and the guard line is about120mm.
