Transformer Pressboard Angle Ring

Transformer Pressboard Angle Ring is a formed insulating structural part manufactured from high-density cellulose pressboard. It features outstanding dielectric strength, uniform density and good oil resistance, maintaining stable insulation performance in transformer oil. The angle ring is specially designed for coil end insulation of oil-immersed power transformers, used to smooth electric field distribution, protect winding edges and avoid partial discharge. We provide custom molded and segmented angle rings according to customer drawings. Precise dimension and smooth surface.
