Description
Aluminum anti corona rings, also called aluminum corona control rings, they are the toroids of conductive materials, usually aluminum alloy, which are attached to a terminal of high voltage equipments. The role of the aluminum anti corona rings are to distribute the electric field gradient and lower its maximum values below the corona threshold, preventing corona discharge. Aluminum anti corona rings are used on very high voltage power transmission insulators and switchgears, and on scientific research apparatus that generates high voltages.

FAQ
1.What Is Anti Corona Ring Packaging?
- Highv has professional packaging team who can adopt developed packaging technology and packaging style to ensure the aluminum anti corona rings packaging quality.
- Standard sea packing, the corona rings 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 products measurements and quality information.

4.What Are Aluminum Anti Corona Rings Surface Treatment?
Usually the polishing silvery bright is the final main surface finish of the aluminum rings not only for the indoor high voltage laboratory centers but also for the outdoor transmission lines.
The surface finish roughness is Ra3.2. The corona rings production process is according to DIN ISO2768-MK general tolerances.
Other manufacturing standard includes general tolerances for welded constructions, tolerances for lengths, angles, tolerances for shape and position, etc will be in accordance with EN ISO 13920-B-F.
5.What Is MOQ of Aluminum Anti Corona Ring?
If the mould is ready on stock, the MOQ will be less. 1 piece corona ring is acceptable.
If you need customized ones, the trial order MOQ is will be negotiated.
6.What Is The Delivery Time?
It depends on your corona rings order total quantity.
Usually from the start of the order to the completion of production for about 2-3 weeks.
