According to statistics from the International Energy Agency, the annual maintenance cost of power equipment caused by wire vibration exceeds 3 billion U.S. dollars, and the loss of power outages caused by failures is even more difficult to calculate. At this time, the effect of spiral vibration damper​ appeared. Spiral vibration damper is not a simple buffer device, but through specific structural design and material characteristics, it actively cancels the vibration energy of the wire and cuts off the hidden dangers of failure from the source.

​The working principle of spiral vibration damper is to weaken the vibration energy generated by the overhead wire under the action of wind through the dual effects of energy dissipation and vibration suppression, so as to prevent vibration from causing damage to the wire and related metal fittings. When the wind blows through the overhead wire, periodic eddy currents will form on the back of the wire. This eddy current will produce alternating pneumatic forces on the wire, causing the wire to vibrate laterally perpendicular to the wind direction, which is the breeze vibration. The frequency of this vibration is higher and the amplitude is small, but the long-term continuous effect will cause the wire to produce repeated bending stress at the suspension point, connecting fittings and other parts, resulting in fatigue and fracture of the wire, and it will also intensify the wear between the fittings and the wire, shortening the service life of the equipment. Spiral vibration damper can effectively suppress breeze vibration in response to this problem through special structural design and material selection.

Spiral vibration damper is a professional device used on overhead transmission lines to suppress the breeze vibration of wires. Under the action of a stable breeze, the wires of overhead transmission lines will produce periodic vibration perpendicular to the direction of the line, which is what we call breeze vibration. This seemingly slight vibration, if it persists for a long time, will cause metal fatigue of the wire, which will cause serious problems such as broken strands and disconnections, and pose a great threat to the safety and stability of power transmission. Through its unique structural design and physical principles, spiral vibration damper can effectively consume vibration energy and control the vibration amplitude of the wire within a safe range, thereby extending the service life of the wire and ensuring the reliable operation of the power system.

The working principle of spiral vibration damper is based on the energy dissipation theory of mechanical vibration. When the wires of an overhead transmission line vibrate under external forces such as wind, the anti-vibration whip will move synchronously with the vibration of the wires.

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.

In the operation of industrial equipment, spiral vibration damper is an important vibration damping component, and its performance will affect the stability and service life of the equipment. Therefore, in order to make the shock absorber run more stably and for a longer time, we should adopt scientific maintenance and care methods. Our company's suggestions to you are as follows:
