¡¡Insulation for transformers Pressboard Class 2|- Pre-compressed Press Boards|Laminated Pressboard£º from 100% Unbleached sulphate wood-pulp. Cardboard makes which on the intermittent type board machine .
Its characteristic is: Material free of strain,very flat , thickness even, the surface smooth, the mechanical strength high, has the obdurability and the electric insulation.We supply pressboard in sheets and presspaper in rolls as well as components of pressboard for production of output transformers and distribution transformers.

Components and insulating sheets of pressboard are used in oil-cooled power transformers and distribution transformers primarily due to their high purity, mechanical strength and optimal oil-impregnability. The components formed of pressboard, such as angle rings, snout segments and end leads, enable an exact adaptation to the electric field conditions prevailing in the transformer.

Especially in the sector of high field strengths, the dimensional stability and good dielectric features are of great advantage. Special forming and pressing procedures are employed in the manufacturing technology of the pressboard components.
