Product Description
Transformer presspaper is made of high-purity 100% sulphate wood pulp processed by high-pressure processing. This product has high chemical purity and high mechanical strength. After immersion, it has both mechanical and electrical properties.
Press Paper (Kraft paper) is a surface insulation material which is resistant to high voltage and a high capacity for impregnation with transformer oil (dielectric mix of oil-cellulose). Kraft paper is made of 100% sulphate wood pulp. It is a high strength paper with excellent electrical properties. It is generally used by manufacturers to meet their need of insulation with an optimum combination of electrical and mechanical strength, low permittivity and maximum oil absorption. 
It is best suited for coil winders, insulation in motors, transformers, manufacturing of laminates etc. 
   Transformer presspaper is widely used in oil-immersed transformers and reactors, capacitors, switches, etc.
Thin electrical insulation paper is made of 100% kraft pulp. With good electrical and mechanical strength, Which is widely adapted for insulating materials in electrical. electronics, instruments and switches. It also can be used for the 6520 polyester film composite foilbase paper.

-Coil Winding 
-Insulation in electrical machines 
-Cable covering

Material : 100% non-bleached sulphate coniferous wood pulp from Sweden and Canada .
Transformer Insulation Paper Quality Standard : IEC60641-3-1:2008
     Transformer board is widely used in Inductor , Reactor , Power transmission and Transformation equipments . Our transformer board has higher mechanical and electrical strength , higher tensile strength , lower compressibility and bending performance .
