High voltage corona ring design is the basic and important part on corona control project. Aluminum corona rings and grading rings are mainly used in power transformer bushing, high voltage laboratory, impulse voltage generator, insulator, surge arrester and other high voltage systems. It is easy to operate, convenient to move, and fast to install.
Here let Highv team introduce high voltage corona rings design process. Then you will be able to get a clear and a crisp understanding of that.
Choose The Right Material For High Voltage Corona Ring Design
Aluminum alloy is the main material which have good weldability for corona ring design and production process. After the welding production, highv staff will set about doing polishing process. As you know, the soft aluminum material is easily for polishing for making sure the good corona effect. The ring are made of aluminum sheet and aluminum pipes. The bending tube production is easily for small rings. Because we only need the pipe bending machine to finish this step. The large rings production process is more difficult.
Grade 3A21, 6061, 6063 aluminum material are on highv stock. Before design the rings, we will confirm the right material with customers. More advantages of the common materials in corona shielding rings.
In Power Transformer Bushing Application
The Bushing of power transformer is a type of porcelain or ebonite post insulator put on the top or side of the transformer tank through which connections are made to the external circuit. Transformer bushing types are RIP bushing and OIP bushing.
The Type Of High Voltage Corona Ring Design
Here two types of ring will be introduced. One is single ring without any brackets. Another one is known as corona ring set. It is also known as phase to earth ring set. The detailed design drawings will be offered by customers. Of course highv team could also help customer redesign new moulds and drawings.

Single Ring VS Corona Ring Set Detailed Design Process
Highv is professional at independent development and design. Our professional engineers team are skilled at AUTO CAD, PROE, SOLID WORKS and UG softwares. We are able to design, develop, produce and deliver rings according to customer detailed drawings, samples or just an idea. If the mould is our stock standard, the mould is free of charge. If it is customized one, the extra high voltage corona ring design drawing and fee will be needed.
In fact, the diameter of ring body have the main influence for corona effect. For example, 750mm-100mm outside diameter with 3mm thickness wall thickness ring is widely used for 220kV power transformer bushings.
Here we should introduce our processing capabilities of the large outer diameter of rings. The biggest diameter dimension of super corona ring is 16000mm. And pipe inner diameter of ring is 3000mm. Wall thickness of pipe will be from 2.0mm to 10mm. During the production process, our team will check the sizes frequently and input our Just-in-Time record. This could ensure all corona rings are within the good tolerances.
Single Ring Design:
- The Right Aluminum
- Material
- Outside Diameter
- Inner Diameter
- Pipe Diameter
- Wall Thickness Of Ring Body
Corona Ring Set Design:
- The Right Aluminum Material
- Outside Diameter
- Inner Diameter
- Pipe Diameter
- Wall Thickness
- The Horizontal Welding Bracket
- The Vertical Welding Bracket
- Other Welding Part
- Installed Flange Tube
- Other Fasteners (Nut, Bolts, Gasket, Lifting Eye, etc)
When it comes to aluminum high voltage corona rings design and production, Highv’s 30 years of manufacturing experience will really show. Corona ring design is a long term process which need our technical team update their minds and skills in every day.
