Product Description

Outdoor High-voltage Composite Insulator Electric Power Fittings Grading And Shielding Corona Rings
 

To mitigate the impacts of corona, corona rings are typically installed on one or both ends of the insulator, attached to the end fittings. While corona rings are generally deemed necessary for system voltages of 230kV and above, there are instances where lower system voltages may necessitate their use for enhanced corona protection.

The corona ring is needed at the line end of the insulator, right at the end fitting and rubber interface, which is the area of highest electrical stress on the sheath of the insulator. As the application voltage increases, the diameter of the corona ring  increases to effectively grade of the electric fields.
