Calendared Pressboard

Calendared pressboard undergoes a meticulous manufacturing process. Through calendaring, the pressboard is compressed between rollers to achieve precise thickness and uniform density, resulting in a smooth and consistent surface finish. Renowned for its exceptional insulating properties, our calendared transformer pressboard provides reliable protection against electrical arcing and short circuits within transformers. Its high mechanical strength and thermal stability ensure optimal performance even under the most demanding conditions. Ideal for use in oil-filled transformers, our calendared pressboard meets stringent industry standards and is classified into various insulation classes, offering versatility to suit diverse applications
