Product Description
Electrical Insulation Presspaper/PressboardElectrical Insulation Presspaper/Pressboard
Insulation Pressboard is a special product based on pure cellulose taken from long-fibred coniferous wood. This is structured into a fibrous tissue without additional adhesive and then pressed. Due to its high chemical purity, pressboard is excellently suited as an insulation material in electric machines, capacitors and oil-filled transformers. 100% wood or cotton thick board is characterized by its high density.
Insulation class A (105 °C)
Hot-pressed Pressboard, 100 % sulphate pulp
High hardness and stiffness
Low shrinkage and compatibility
High purity and mechanical strength
Good compatibility with liquid dielectrics
Further processing is ensured since the pressboard can be punched, folded, cut and formed without difficulty.
To use as insulations material in Power and Distribution Transformers
It is the base material for components like cyclinders, strips, spacers, rings. washers, plates, machine formed and moulded parts, punchings and laminates.
