GBS Electrical Pressboard Paper, as an indispensable dielectric material for oil-immersed transformer insulation, is produced from 100% unbleached cellulose taken from long fiber coniferous wood. This is structured into a fibrous tissue without additional adhesive and then pressed. Its excellent chemical purity, mechanical strength and optimum oil impregnability make the product be widely used in electrical transmission and distribution equipment like Power Transformers, Shunt Reactors and Instrument Transformers etc.
Features
1. High mechanical and electric strength
2. Insulation class A (105ºC)
3. Uniform clear color
4. Hot-pressed Pressboard,100 % sulphate pulp
5. High hardness and stiffness
6. Low shrinkage and high compatibility
7. High purity and mechanical strength
8. Further processing is ensured since the pressboard can be punched, folded, cut and formed without difficulty.
9. Size: 1150*800mm /1000*2000mm
10. Thickness: 0.08mm-4mm, can be customized
