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.

Corona Rings function:

High voltages can result in unwanted noise (RIV) and corona.
To minimize the effects of corona, corona rings are applied to one or both ends of the insulator (attached onto the end fittings). Typically, for system voltages 230 kV and above, a corona ring or combination of rings is necessary. However, some application may require rings are lower system voltages when addition corona protection is required high contamination, high altitude, or applications with tight phase spacing. Refer to the Corona Ring section of the Application Guide for detailed information or contact the factory for these special cases or any corona ring application assistance.

Recommended Corona Ring Application for line post insulators:
Used on the line end or tower end (end fitting)
Voltage: 138kv, 161kv, 230kv, 345kv, 500kv

The Smart Fit corona rings are designed around the needs of the end user. It is easy to install, unidirectional (not able to install in the wrong direction), and can be installed or removed with hot stick tools. By making the ring a one-piece design, we have eliminated the problem of missing or lost parts. This was made possible by designing a unique clamping mechanism that uses two bolted keepers to secure the ring to the insulator. Additionally, the clamping section was designed such that the ring can only be installed in one direction, which eliminates the problem of misapplied rings. As a final step, the ring was designed with a split (opening) to allow installation with hot stick tools.

Three Ring Diameters are available for use on all suspension insulator styles: 8” Corona Ring, 12” Corona Ring, and 17” Corona Ring

For insulators 230 kV and above, High-V Electrix recommends use of Line Post Corona Rings. The Application depicts typical corona ring usage on suspension Insulators. For corona ring usage on special applications, environments, and elevations, please contact us.

Corona Ring Material

Aluminum, steel and copper are main material for Corona Ring and shielding components.

The corona ring packing can be done by wooden case and cartons.

1). Wooden Packing:
Wooden packing suitable for heavy weight corona rings. For export, Fumigation Certificate will be necessary when case is made of solid wood.
Fumigation Mark

Fumigation requirements:
1.No bark allowed on wooden package.
2.Ship fumigated wooden package as soon as possible, ensure separate storage and segregation with non-fumigated wooden materials.
3.Validity of the certificate of fumigation is 21 days.
Inquire local ship agency whether fumigation is necessary every time after learning the lot package material, booking with a certain answer. Method of wood case fumigation include chemical preparation method and heat treatment.

2). Carton Packing:
Carton Packing always light weight and convenient for moving by hands. Its suitable for light weight rings.
