High Purity and Pliability Electrcial Crepe Paper For Oil-filled Transformers

Short Description:

GBS’s transversely Crepe Paper Tube has high absorption rate of oil and good dielectric strength which makes it extensively used especially in oil immersed transformers, instrument transformers, reactors and other parts of package insulation, especially as lead parts of the insulation package, thereby improving the electrical insulation and mechanical properties of the product structure.

Using these insulating sleeves will provide superior insulation and heat dissipation, thereby helping to extend the lifespan of transformers.

Our crepe paper uses different base paper and various crepes for easier assembly, meets requirements for different dimensions.

High Purity and Pliability Electrical Crepe Ppaer for Oil-Filled Transformers

Features

1. Made from 100% sulfate wood pulp;

2. Class "A" insulation (105 °C);

3. Flexible size: different ID and OD as per client needs;

4. 300% more strength in mechanical and cross mechanical directions, more resistant to breakage;

5. Crepe surface means greater surface area which helps to retain more oil and hence lowers the working temperature of the transformer compared to kraft paper;

6. Color: natural brown, beige;

7. Manufactured using longer fibers of pure wood pulp.

Standard: JB/T 10441.3-2004
