Aluminum Shielding 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

Aluminum Shielding Rings: The Ultimate Guide
The aluminum 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 shielding rings? How to design them?
In this guide, we will show you details about all.
What Are Aluminum Shielding Rings?
The aluminum shielding ring, also called an anti-corona ring, is a toroid of conductive material, usually aluminum alloy, which is attached to a terminal of high voltage equipment.
The role of the corona shielding ring is to distribute the electric field gradient and lower its maximum values below the corona threshold, preventing corona discharge.
Corona shielding ring is used on untra high voltage power transmission insulators and gas insulated switchgears, and on scientific research apparatus that generates high voltages.
Corona shielding rings are typically installed on super high voltage power line insulators.
Corona shielding rings prolong lifetime of insulator surfaces by suppressing the effects of corona discharge.
Corona shielding rings may also be installed on the insulators of antennas of high-power radio transmitters.
However, they increase the capacitance of the insulators.
How Do Aluminum Shielding Rings Work?
The aluminum shielding 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.
