High Voltage Corona Ring Packaging & Shipping
- Highv has professional packaging team who can adopt developed packaging technology and packaging style to ensure the corona ring packaging quality.
- Standard sea packing, the corona ring packing can be done by wooden case and carton box. The wooden case and corona rings contact parts must be padded with foamed paper or rubber. Wooden case four corners shall not be smaller than the size of the corona rings. Corona Ring’s surface is wrapping foam paper, and four sides contacting with wooden case with foam mat protection.
- In addition, clear labels are tagged on the outside of the packages for easy identification of the corona rings measurements and quality information.
*Other special packaging will be designed as customer’s request

High Voltage Corona Rings: The Ultimate Guide
The high voltage corona ring is one of the most important components in power industry.
With the development of science and technology, more and more quality rings are widely used in the transformers, bushings and insulators industries.
So what are the benefits of using them? What’s the production process of corona rings? How to design them?
In this guide, we will show you details about all.
What Are High Voltage Corona Rings?
The high voltage corona rings, also called aluminum corona rings, they can be used in high voltage test equipment and power systems (substations, high voltage transmission line, AC voltage system, etc.) and are mainly made of aluminum alloy.
Generally the high voltage corona ring needs to be polished bright to achieve more smooth and no burr surface finish to ensure better corona control effect.
Corona ring is widely used on the end fittings of high voltage bushings and other high voltage testing equipments. High voltage can result in unwanted noise and corona, so corona rings are needed.
The high voltage corona ring is suitable for the voltage form of alternating current (AC), which can distribute the high voltage evenly around the object to ensure that there is no potential difference (PD) between the various parts of the ring.
How Do High Voltage Corona Rings Work?
The high voltage corona ring is widely used for high voltage industry to suppress corona effectively. At sharp point (like bushing head) the electric field is high which results in corona. Aluminum corona ring ( corona shielding ring) should be installed at this point. The ring is suitable for the voltage form of alternating current (AC), which can distribute the high voltage evenly around the object to ensure that there is no potential difference (PD) between the various parts of the ring.
The larger outside diameter, smooth polishing surface finish of aluminum corona rings can help control the local electric field. So electric field gradient reduces and suppresses the corona. As the testing voltage increases the outside diameter of the required corona ring/shielding ring must also increase to obtain better corona control effect. Highv has rich decades of experience in corona rings design and shielding solutions technology, uses advanced manufacturing equipments and high efficient drawing software, which can make sure user’s every project to run more smoothly, safely and efficiently.
