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.

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:
