Electrical Grade Insulating Presspaper is manufactured from quality cellulose fibres to meet the insulation requirements of motor, capacitor, and transformer manufacturers. They are made without additives in a multi-vat cylinder machine and are subsequently calendered to achieve a smooth finish. The manufacturing process results in homogeneous layers with excellent mechanical and electrical strength.
Electrical Grade Insulating Presspaper is ideal for use in: transformers, capacitors, slot insulation, motor slot lining, wraps, high voltage switchgear components, and many similar applications.
Conforms to the electrical and mechanical strength properties as specified by IEC 60641-2
Thickness: 0.10mm, 0.15mm, 0.20mm, 0.25mm, 0.30mm, 0.35mm, 0.45mm, 0.50mm
