Description

Insulation for transformers Press board Class 2|- Pre-compressed Press Boards Laminated Press board from **0% 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 ob durability and the electric insulation.We supply press board in sheets and press paper in rolls as well as components of press board for production of output transformers and distribution transformers. Components and insulating sheets of press board 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 press board, 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
