The working logic of corona ring coil is to achieve precise suppression of corona discharge through electric field optimization.

The corona ring coil on the insulator is an important protective component designed for this problem. It is not a simple metal ring, but a professional equipment that can optimize the distribution of electric fields and suppress corona discharge through special structures and installation methods. It is an indispensable insulating auxiliary component in high-voltage transmission lines.

Before officially entering the installation process, it is necessary to confirm the installation environment and working conditions of corona ring coil. The construction team needs to verify key parameters such as the voltage level of the line to be installed, the type of insulator string, and the specifications of the fittings. It also needs to evaluate the on-site construction environment to ensure that the purchased corona ring coil is fully adapted to the on-site equipment and construction environment.

​The corona effect is a special discharge phenomenon under a high-voltage electric field. When the line voltage rises to a certain extent, the charge density on the surface of the wire increases abruptly, especially at the tip, joint or burr, the electric field strength will be quickly concentrated.

The main purpose of corona ring coil​ is to suppress the corona discharge phenomenon of high-voltage equipment and protect the insulation system of the equipment from the root cause. The secondary purpose of corona ring coil is to reduce energy loss and electromagnetic interference and improve the overall energy efficiency of the transmission system. In addition, the use of corona ring coil in simplifying the operation and maintenance process and reducing long-term operating costs is in line with the pursuit of project economy by B-side buyers.

Our corona ring coil adopts a streamlined arc structure, and the curvature and diameter of the ring body are accurately optimized through finite element analysis software, so that the electric field strength on the surface of the conductor can be evenly dispersed to the surface of the ring body, completely eliminating the concentration of the electric field, and avoiding the generation of corona discharge from the source.
