Transformer Pressboard Sector End Ring

Transformer Pressboard Sector End Ring is a segmented fan-shaped insulating component precision processed from high-density cellulose pressboard. It features high mechanical strength, stable dimensional accuracy and good oil compatibility. This sector end ring is widely used for coil end support, spacing and heat dissipation of oil-immersed power transformers. It effectively stabilizes winding structure, balances pressure and ensures reliable insulation performance under high voltage conditions. Custom sizes and precision machining are available. Stable quality and smooth finish.
