Rings & Winding End Structures
Electrostatic Shielding Rings
Also known as: Electrostatic Rings, Static Shielding Rings, Grading Rings
Electrostatic shielding rings are used at transformer winding ends to equalize electric-field distribution and reduce local field concentration. Ring frames are typically insulated and may be combined with conductive foil and crepe paper according to the design.
Dimensions, materials, tolerances and testing requirements are confirmed according to customer drawings and order specifications.
