High Voltage Aluminium Corona Rings 6063 For High Voltage Test Laboratory

High Voltage Aluminium Corona Rings 6063 For High Voltage Test Laboratory

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 for detailed information through contacting our highv team for these special cases or any corona ring application assistance.
