Corona rings are used primarily as a control, or grading component, in the electrical utility industry for high voltage applications such as switches, substation bus hardware, and dead end assemblies on transmission lines.
Such ring devices of various sizes and configurations act to reduce radio and television inteference which is a direct result of corona, a phenomenon created when the potential of a conductor in the air is raised to such a value that the dielectric strength of the surrounding air is exceeded.

Corona Control Rings with Brackets Corona ring is classified into closed corona ring of ordinary type, bird-preventing helmet closed ring, semi-ring by structure; die-cast aluminum, aluminum tube and stainless steel tube by material. The abovementioned rings are all of current-leading structure, that is, in the case of pollution flashover or lightening flashover when the composite insulator is operating, the current will be directly led to the terminal of end fittings instead of flowing through the terminal sheath and crimping part, so as to protect the seal part from damage and the crimping part from the impact of thermal expansion thereby resulting in the grip strength reduction of the metal fittings.

This Aluminium Corona Ring Casting ensures accurate casting of aluminum corona to allow easy fitting to a high voltage equipment for distributing electric field gradients. Dimensional defect on the designed good leads to corona discharge so we deliver this product in precise shape and finish. This product retains dimensional stability even at high temperature which makes it highly preferable for casting aluminum. This product is molded by implementing pioneering extrusion methods under the guidance of skilled professionals. We ensure on-time delivery of this Aluminium Corona Ring Casting in several shapes, designs and finishes to match end customers’ requirements.

The corona discharge of some grading rings is serious on 500 kV compact transmission line in China,due to the improper structure design and installation. In order to suppress the corona and avoid the same fault in the future,it is necessary to optimize the structure of the grading ring. Consequently,the grading rings having obvious corona discharge were found out by observing hardware fittings along lines with UVI (ultraviolet imager),then the electric field distribution of the grading rings was calculated using three-dimension FEM(finite element method). After analyzing the electric field distribution to get the causes of corona discharge,the structure of grading ring was optimized to reduce the maximum electric field intensity on its surface from 3868 V/mm to 2475 V/mm. According to the optimization proposals,new grading rings were manufactured and hung on operating lines. The observations by UVI show that the new ones have no corona discharge on their spheres and bodies which validate the optimizations. This study can provide experiences and references for the design of anti-corona hardware fittings on high voltage transmission lines

The potential gradient (electric field) across an insulator is not uniform, but is highest at the end next to the high voltage electrode. If subjected to a high enough voltage, the insulator will break down and become conductive at that end first. Once a section of insulator at the end has electrically broken down and become conductive, the full voltage is applied across the remaining length, so the breakdown will quickly progress from the high voltage end to the other, and a flashover arc will start. Therefore, insulators can stand significantly higher voltages if the potential gradient at the high voltage end is reduced.

The grading ring surrounds the end of the insulator next to the high voltage conductor. It reduces the gradient at the end, resulting in a more even voltage gradient along the insulator, allowing a shorter, cheaper insulator to be used for a given voltage. Grading rings also reduce aging and deterioration of the insulator that can occur at the HV end due to the high electric field there.

The role of the corona ring is to distribute the electric field gradient and lower its maximum values below the corona threshold, either preventing corona discharge entirely or transferring its destructive effects from the valuable hardware to the expendable ring.

corona rings designed to effectively eliminate corona effects on substation connectors or equipment. Artisan company calculate shield sizes according to the actual voltage requirement and overall arrangement. In addition to the shields for connectors, corona shields design and manufacture to protect HV terminals of apparatus like bushings, HVDC valves, transformers, current or voltage transformers, and similar apparatus.

The large diameter, smooth spherical shapes of corona rings/toroids/balls helps to control the local E-Field, thereby suppressing the generation of corona. As the output voltage increases the diameter of the required corona ring/toroid/ball must also increase to obtain effective corona suppression.
