The generation of corona stems from the fact that the electric field strength on the surface of the high-voltage conductor exceeds the critical value of air breakdown, resulting in the ionization of air molecules to form a partial discharge. It is commonly used in substation busbars, transmission line joints, high-voltage motor windings and other parts. This phenomenon is more prominent in humid, high-altitude or heavily polluted environments. This phenomenon produces high-frequency noise that interferes with peripheral equipment and releases ozone and nitrogen oxides to corrode insulating parts. If it is heavy, it will cause conductor heating and power loss to surge, and long-term accumulation may even cause major accidents such as insulation breakdown and equipment burning.
Traditional methods of reducing corona, such as manually polishing the surface of the conductor to reduce roughness, increasing the thickness of the insulating layer, or installing a simple shield, have obvious limitations. Manual processing is difficult to ensure accuracy, and the concentration point of the electric field cannot be completely eliminated. Thickening the insulation layer will increase the volume and weight of the equipment, increasing the difficulty and cost of installation. The adaptability of ordinary shielding covers is poor, and the protection effect is unstable in complex voltage levels and equipment structures. These solutions are not only difficult to meet the needs of modern power systems for efficient and reliable protection, but may also cause secondary hidden dangers due to adaptation problems, which puts buyers in the dilemma of high investment but poor effect.
As a supplier that has been deeply engaged in the field of power fittings for many years, our corona ring coil breaks through traditional protection bottlenecks in all directions from design, materials to craftsmanship, and provides global buyers with a better choice. In terms of design, we use three-dimensional electric field simulation technology to accurately optimize the curvature and diameter ratio of the corona ring coil, evenly disperse the electric field concentrated on the surface of the conductor to the curved surface of the ring, and cut off the conditions for corona generation from the source, completely eliminate the phenomenon of partial discharge.
In terms of material selection, our corona ring coil is made of high-strength alloys with high temperature resistance, which have good fatigue resistance and corrosion resistance, can adapt to high temperature environments, and are not easy to age or deform. In practical applications, our corona ring coil has won the recognition of customers around the world for its convenience and economy. Corona ring coil adopts a pre-twisted ring design structure and is made of lightweight materials. No professional heavy equipment is required for on-site installation. Two technical personnel can complete the installation of a set of devices within 1 hour, significantly shortening the construction cycle. At the same time, the lightweight design of corona ring coil will not increase the load-bearing burden on the equipment, and can avoid additional stress damage to the tower, bracket and other structures. Up to now, our corona ring coil has served more than 100 power projects in more than 20 countries around the world, and has achieved obvious effects such as corona noise cancellation after installation, 5% to 8% reduction in annual power loss, and 55% reduction in equipment failure rate. The customer repurchase rate reached more than 80%.
For B-side buyers, choosing corona ring coil is not only a technical decision, but also a guarantee of the long-term value of the project. Choosing our corona ring coil can not only provide stable and reliable protection for your project, but also create continuous economic value for you by reducing energy consumption and extending equipment life.
