Product Name: High Voltage Corona Rings
Size: As Drawing Request
Surface: Polishing Silvery Bright, Ra3.2
High Voltage Corona Rings Specification
High voltage corona rings are 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.
High voltage corona rings are 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 high voltage corona ring are 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 corona ring needs to be polished bright to achieve more smooth and no burr surface finish to ensure better corona control effect.

High Voltage Corona Rings Packing
- Our company has professional team can adopt developed packaging technology and packaging style to ensure the 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.
- High strengh
- Excellent silvery bright finish
- Corona control advantage
- High moistureproof
- Competitive price with good quality
- Low MOQ (1 piece is even acceptable in some special conditions)
- Customized sizes and specifications /OEM is available
