800KV Aluminum High Voltage Corona Rings For Power Transmission Line
Keywords:
- Corona ring which is also known as corona control ring or protective ring
- High voltage corona ring is used on different high voltage systems, such as GIS (Gas Insulated Switchgear), Arrestor, High voltage bushing, Power Transformer, Power cable, Instrument transformer, High voltage test laboratory, Impulse voltage test system, High voltage capacitor, AC-DC Converter, HVDC Products and so on.
- Corona ring is used to ensure a uniform voltage distribution along the length of an electrical device
- The main purpose of the high voltage corona ring is to reduce the potential gradient along the insulator, preventing premature electrical breakdown
- Here 800kV high voltage corona rings for power transmission line
Product Description:
| Main Material of Ring Body | Aluminum 6061, 3A21, 316 Stainless steel and copper are main material for high voltage corona ring and other shielding components production |
| Bending Tube Wall Thickness | 2.0mm-10.0mm range or according to customers’ drawings |
| Production | Aluminium Pipe Bending and Welding for high voltage corona ring |
| Voltage Grade | 800kV |
| Outside Diameter | 500-16000mm or as customer’ requests |
| Standard | ASTM, DIN, ISO, Non-Standard or according to customers’ drawings requirements |
| Certificate | ISO,SGS, TUV etc. |
| Applications | Power transformer, Cable hardware, High Voltage Bushing Test, high voltage laboratory test etc. Corona Rings are used on the end fittings (line end or tower end) of post insulators and suspension insulators. High voltages can result in unwanted noise (RIV) and corona, so Corona Rings are needed. |

Packaging:
The corona ring packing can be done by wooden case and cartons. Wooden packing is suitable for heavy weight corona rings. For export, Fumigation Certificate will be necessary when case is made of solid wood. Carton Packing always light weight and convenient for moving by hands. It's suitable for light weight corona rings. When customers inquiry to us, the pictures of package will be attached in quotation list.

FAQ:
1) Q: What’s painting of the high voltage corona ring?
A: During normal processing, the corona ring is made of the aluminum and stainless steel.The surface finish does not require the painting. HighV supply painting service according to customers requirement. Such as Color painting, Galvanized etc. Other Tungsten plating, copper plating, etc, are available.
2) Q: How does you factory do regarding quality control ?
A: Our Highv team always attach great importance to quality controlling from the very beginning to the very end. We could help customer do the third party test of PSI or SGS before shipment.
3) Q: In case the high voltage corona ring exists problem, how to do after sales service?
A: To be honest, mistakes happen in business. But not all the suppliers have the problem-solving ability. Some of them avoid to take responsibility. Some of them want to solve the problem, but have no ability to pay for the mistake. Highv team will be honest to take responsibility for all of our mistakes. We will provide new parts required with free of charge by international express. More and more customers choose us because we take care of business.
