Pre Compressed Board
Pre-compressed board Insulation Material

High-Performance Insulation for Reliable Transformer Operation

Pre-compressed board, also known as pressboard, is a vital solid insulation material used extensively in power and distribution transformers. Made from high-purity cellulose fibers derived from unbleached kraft pulp, these boards are mechanically and chemically treated to ensure excellent electrical, mechanical, and thermal properties.

Key Features:

  • High Electrical Insulation: Excellent dielectric strength and insulation resistance make it ideal for use in high-voltage environments.

  • Dimensional Stability: Manufactured under high pressure and temperature, ensuring uniform thickness and minimal shrinkage or expansion.

  • Mechanical Strength: Capable of withstanding high mechanical stress in core and coil assemblies.

  • Thermal Endurance: Can operate reliably under high thermal stress conditions encountered during transformer operation.

Applications in Transformers:

  • Layer and barrier insulation in oil-immersed power and distribution transformers.

  • Used in winding spacers, supports, and as insulation between windings and core.

  • Component manufacturing such as cleats, spacers, cylinders, and rings.
