                                                             Insulation Compressed Pressboard
       Insulation Compressed Pressboard is made of unbleached sulphate wood pulp and is made by viscous beating. It is used in electric motors, power meters, etc., and has high tightness and withstand voltage. Generally, there are air insulating paperboard and oil insulating paperboard, etc., and have good insulation, heat resistance, durability and the like.
      Insulation Pressboard transformer is an electrical cardboard used for supplying motors, electrical appliances, meters, switch transformers, etc. and their components. The purpose of the insulating paperboard is to: make insulating materials for air dielectrics such as slots, coils, gaskets, protective layers, etc.; or as spacer materials in powe transformer oil tanks at temperatures not higher than 90 °C.
      Insulation Pressboard is divided into two types: flat plate and roll paperboard, and flat cardboard is thicker than 0.5mm. A roll paperboard having a thickness of 0.5 mm or less is used. The raw materials of the insulating paperboard are unbleached kraft pulp and cotton pulp, and the two raw materials are separately beaten (the degree of beating is controlled at 38 to 42 ° SR). Purified water must be used in production. Pipes and slurry pumps should be cleaned and washed, and impurities containing conductive components must not be mixed.

ZTELEC Insulation Compressed Pressboard has good mechanical strength and high electrical strength.
