High Voltage Corona Balls and Spheres

 High Voltage Corona Balls and Spheres

Eastern Voltage Research now offers a wide array of sizes of high voltage corona balls and spheres. These are very useful for coronal suppression for various components in high voltage assemblies as well as used in spark gaps. Sizes from 1/4" diameter through 4" diameter are available as well as varying thread types.

Corona balls are CNC machined with a non-polished finish and available in both brass and aluminum.

IMPORTANT NOTE- Machining Charge per Order

All corona spheres are custom machined to order and do require a $15.00 machining charge per order. When checking out, please make sure to add the $15.00 machining payment below to your order. The machining charge is required whether you order a single 1/4" corona ball or one hundred four inch balls. We appreciate your understanding on this. Thank you
