CZPTal Insulation presspaper Pressboard is created from one hundred% superior sulfate insulating wooden pulp.
Figures and Apps for CZPTal insulation paper/ presspahn paper /pressboard has substantial chemical purity, exceptional elongation, great Mechanical and dielectric Power For oil-immersed transformers, capacitors and switches
Insulation course A (a hundred and five °C)
Natural-coloured
Hot-pressed Pressboard, 100 % sulphate pulp
High hardness and stiffness
Low shrinkage and compatibility
High purity and mechanical energy
Good compatibility with liquid dielectrics
Further processing is ensured because the pressboard can be punched, folded, cut and formed CZPT trouble.
