Rigid Electrical Insulation for Transformers & High-Voltage Equipment
Press board is a high-density cellulose-based insulation material widely used in power and distribution transformers, switchgear, and electrical machinery. Manufactured from pure, unbleached kraft pulp, it offers excellent mechanical strength, dielectric properties, and oil absorption, making it ideal for use in oil-filled electrical equipment.
This rigid insulating material is valued for its dimensional stability under high pressure and temperature, ensuring long-term performance in demanding electrical environments.
