Transformer Insulation Pressboard Angle Rings

Transformer pressboard angle rings are rigid insulation components used in winding end insulation structures to maintain electrical clearance, support coil geometry and improve the overall insulation layout inside oil-filled transformers, distribution transformers and power transformers. They are usually produced according to drawings or confirmed dimensions and are selected where dimensional accuracy, oil compatibility and mechanical stability are important.

We supply insulation rings and angle rings made from high-grade electrical insulating materials according to customer drawings, technical requirements, or sample parts. With extensive export experience in transformer insulation materials, we understand the quality expectations of transformer factories, repair companies, and industrial importers.
