Specifications transformer used Insulating paper Natural brown:
1 better machinery intensity
2 higher resist-electric intensity
3 flat surf
Insulating paper Natural brown is made from 100% superior sulfate insulating wood pulp. It has good dielectric and high mechanical properties. Insulation Presspaper is widely used for tansformers, electric motors, electric apparatus, meters, switches, etc. It also can be used to laminate with polyester film to produce insulation flexible laminates. Features and applications of Insulating paper Natural brown: -high chemical purity, excellent elongation, good mechanical and dielectric strength. -for oil-immersed transformers, capacitors, reactors and switches.
