For many decades, presspaper has demonstrated its value as an insulation class A material. It is made of cellulose fibers and is obtained from a paper manufacturing process without the use of binders.
A proven surface insulation material, Presspahn is resistant to high voltage and a high capacity for impregnation with transformer oil (dielectric mix of oil-cellulose).
This press paper and pressboard is available in a variety of different thicknesses and formats, and can withstand high heat loads for short periods of time.
Presspahn is produced from 100% electrical grade kraft wood pulp and is a designed as a surface insulation material on cellulose for insulation class A.
