Insulation Paperboard for Transformer Applications is a rigid, cellulose-based electrical insulation material designed to provide dielectric separation, mechanical support, dimensional stability, and structural insulation inside transformers. It is commonly associated with transformer pressboard, electrical insulation board, and transformer board. Unlike ordinary paperboard used for packaging, electrical insulation paperboard is manufactured from carefully selected insulating fibers and processed under controlled conditions to achieve the electrical, mechanical, chemical, and dimensional chara...
