Description
Insulation Pressboard is a special solution based on pure cellulose taken from extended-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 materials in electric machines, capacitors and oil-stuffed transformers. 100% wood or cotton thick board is characterized by its large density.
Attributes
Insulation course A (one zero five °C)
Hot-pressed Pressboard, 100 % sulphate pulp
Higher hardness and stiffness
Low shrinkage and compatibility
Large purity and mechanical strength
Good compatibility with liquid dielectrics
Even more processing is ensured since the pressboard can be punched, folded, cut and shaped CZPT difficulty.
Apps
To use as insulations materials in Electrical power and Distribution Transformers
It is the base substance for parts like cyclinders, strips, spacers, rings. washers, plates, machine shaped and moulded parts, punchings and laminates.
