  • Electrical Kraft Paper/Cable Paper for Insulation

    Short Description:

     

     

    Our electrical cable paper, manufactured from 100% high grade sulfate pulp wood without sizing and without filling, and its high density/tightness and low ash provides it with high dielectric constant. This feature allows it to prevent current from flowing through the insulation layer, thus minimizing the risk of electrical faults, short circuits, and other hazards.

    Other advantages as below:

    Mechanical Strength: A key factor to determine whether it’s suitable for layer insulation, because its durability and reliability of the insulation layer will enable it to maintain its performance during application.

    Flexibility: Its flexibility and malleability allows it to be easy to assembly even when the contours of electrical equipment are different.
