Electrical Insulating Press Boards

Our provided range of Electrical Insulating Press Boards is a proven surface insulation material on cellulose basis for the insulation class A. Depending on the type of cellulose, fibre conditioning and machinery settings, We can supply a variety of press paper and pressboard types with very specific characteristics.

The properties and characteristics of the press paper and press board materials are standardized in DIN 7733 and IEC 60641. Besides the high breakdown voltage and the high capacity for impregnation with transformer oil (dielectric mix of oil-cellulose), the pressboard can withstand high heat loads for short periods of time (e.g. 350 A C for a few seconds) because the material has no melting point. Also, the presspaper and pressboard can be punched, folded, cut and in some cases be shaped as well. We offer these Electrical Insulating Press Boards at most affordable prices to our precious customers.
