one. Attributes
- Scorching-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 CZPT difficulty.
2.Apps
Used as insulating material in power and distributing transformer. It is appropriate for strips, cylinders, spacer, plates and structural supports of oil-liquid of distribution transformers, reactor and bushing recent transformer.
