​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.

As an important part of the power communication network, ADSS optical cable assumes important functions such as transmission line monitoring and data transmission. However, ADSS optical cables are exposed to the strong electric field environment of high-voltage transmission lines for a long time, and they are easily affected by corona discharge, electrochemical corrosion and other problems, resulting in aging, fracture and other failures of optical cables. As a protective equipment, the vibration damper corona ring can protect the ADSS optical cable and ensure the safe operation of the cable by optimizing the electric field distribution, suppressing the corona phenomenon, and blocking the corrosion path.

The corona effect is a common physical phenomenon in the operation of high-voltage power equipment. It refers to the discharge phenomenon caused by local ionization of the medium when the electric field strength on the surface of the conductor exceeds the breakdown field strength of the surrounding medium. This kind of discharge is usually accompanied by low light, sizzling sound, and the production of gases such as ozone. A light blue halo can be clearly observed at night or in the dark. The generation of corona effect is closely related to the distribution of electric field on the surface of the conductor. In high-voltage equipment, the smaller the radius of curvature of the conductor surface, the more concentrated the electric field intensity, and the easier it is to cause corona. Corona will not only cause power loss, but also produce electromagnetic interference, noise pollution and corrosive gases, which will adversely affect the insulation of equipment and the surrounding environment.

Transmission lines are exposed to the natural environment for a long time, and wind vibration is one of the main threats to transmission lines. Breeze vibration is a high-frequency and low-amplitude vertical vibration generated by overhead wires under the action of breeze. The main characteristics of breeze vibration are high frequency, small amplitude, small required wind speed and long duration. Breeze vibration can cause major hazards such as fatigue and disconnection of overhead wires, wear of metal fittings, and wear or disconnection of ground wires at the outlet of the clamp. As an anti-vibration metal tool that can suppress the breeze vibration of transmission lines, supply vibration damper can play a role in maintaining the stability of the power grid.
