Presspaper Pressboard Paperboard for Transformer

Description
Insulation Pressboard is a unique solution based on pure cellulose taken from long-fibred coniferous wooden. This is structured into a fibrous tissue CZPT extra adhesive and then pressed. Thanks to its higher chemical purity, pressboard is excellently suited as an insulation content in electric equipment, capacitors and oil-loaded transformers. 100% wooden or cotton thick board is characterised by its large density.

Attributes
Insulation class A (105 °C)
Very hot-pressed Pressboard, a hundred % sulphate pulp
Higher hardness and stiffness
Low shrinkage and compatibility
Higher purity and mechanical strength
Excellent compatibility with liquid dielectrics
Further processing is ensured since the pressboard can be punched, folded, cut and formed CZPT issues.
Apps
To use as insulations materials in Power and Distribution Transformers
It is the foundation substance for components like cyclinders, strips, spacers, rings. washers, plates, device formed and moulded elements, punchings and laminates.
