Pressboard Strip PSP3052 (Transformer strip)
Type B 3.1 in according to IEC 641-1
Description
Pressboard PSP3052 (Transformer Board PSP3052) 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.
Features
Insulation class A (105 °C)
Natural-coloured
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.
Applications
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.
