Insulating kraft paper

insulating kraft paper

  • Insulating kraft paper is manufactured of 100% sulphate pulp. Electrical insulating presspaper has excellent thermal endurance properties. It is elastic so that the conductors can be bent without breaking the paper. 

  • Features

  • ●This paper is highly refined and cleaned to ensure uniform thickness and free from formation

  • Pinholes, un-dispersed fiber bundles and tiny defects

  • ● It is a low-voltage grade insulaing paper well suited for making electromagnetic  wires,power cables of transformers below 35KV and other electrical insulating equipments below 35KV

  • ●This paper has stable electrical and chemical properties, and high physical strength to meet the exacting 

  • needs of our valued customers 


  • Applications

  • Used widely as electrical insulation wrap on aluminium and copper wires by  conductor manufacturers,electrical insulation between layers of wound coils in 

  • electrical motors, in capacitors, transformers & such other electrical equipment

      Thermally upgraded 

       Calendered paper and thermally upgraded paper are two different qualities of the paper. 

       Upgrading is achieved by adding nitrogen to the paper pulp. Nitrogen replaces the oxygen 

       which otherwise oxidizes and ages the paper at high temperature.


  • Coil winding, barrier, core & layer insulation in transformers. It is also used in motors and other electrical applications where high dielectric and physical strength are required.

    Note: Reels can also be supplied in slitted form duly slitted as per desired width of the customer. Specific thickness can also be supplied as per requirement of the customer.
