Description
Insulation Pressboard is a specific product based mostly on pure cellulose taken from lengthy-fibred coniferous wood. This is structured into a fibrous tissue CZPT added adhesive and then pressed. Due to its high chemical purity, pressboard is excellently suited as an insulation content in electric machines, capacitors and oil-stuffed transformers. a hundred% wood or cotton thick board is characterized by its high density.
Functions
Insulation course A (one zero five °C)
Very hot-pressed Pressboard, 100 % sulphate pulp
Higher hardness and stiffness
Minimal shrinkage and compatibility
Substantial purity and mechanical power
Excellent compatibility with liquid dielectrics
Further processing is ensured considering that the pressboard can be punched, folded, cut and shaped CZPT trouble.
Programs
To use as insulations material in Power and Distribution Transformers
It is the foundation material for elements like cyclinders, strips, spacers, rings. washers, plates, equipment shaped and moulded components, punchings and laminates.
