Transformer Insulation Pressboard Sheets

Transformer Insulation Pressboard is a high-density cellulose-based electrical insulation material designed for oil-filled transformers and electrical equipment. Offering excellent dielectric strength, mechanical stability, and oil compatibility, it is widely used for spacers, barriers, and structural insulation components.

Overview

Transformer Insulation Pressboard is a high-performance cellulose-based electrical insulation material manufactured for demanding transformer and electrical applications. Known for its excellent dielectric properties, mechanical strength, and compatibility with transformer oil, pressboard is widely used in power and distribution transformers for structural and insulation purposes.

Pressboard sheets provide reliable electrical insulation, dimensional stability, and moisture-controlled performance, making them suitable for insulation spacers, barriers, winding supports, and fabricated transformer components. Available in multiple thicknesses and densities, transformer pressboard is ideal for both standard and custom electrical insulation applications.
