Description
Insulation Pressboard is a specific solution based on pure cellulose taken from prolonged-fibred coniferous wooden. This is structured into a fibrous tissue CZPT added adhesive and then pressed. Because of to its substantial chemical purity, pressboard is excellently suited as an insulation material in electric powered machines, capacitors and oil-stuffed transformers. one hundred% wood or cotton thick board is characterized by its high density.
Characteristics
Insulation course A (one hundred and five °C)
Hot-pressed Pressboard, one hundred % sulphate pulp
Substantial hardness and stiffness
Minimal shrinkage and compatibility
Higher purity and mechanical toughness
Excellent compatibility with liquid dielectrics
Further processing is ensured since the pressboard can be punched, folded, cut and fashioned CZPT difficulty.
Applications
To use as insulations content in Electricity and Distribution Transformers
It is the foundation material for elements like cyclinders, strips, spacers, rings. washers, plates, device fashioned and moulded areas, punchings and laminates.
