What are the material characteristics of Electrical Insulation Crepe Paper Tube

      Electrical Insulation Crepe Paper Tube is an electrical insulation pipe made of high-purity insulation wood pulp paper that is wrinkled, rolled, and thermally cured. 

Material characteristics of corrugated paper tube for electrical insulation

1.Excellent electrical insulation performance

      High dielectric strength, high insulation resistance, high voltage resistance, corona resistance, suitable for strong electric field environments such as transformers, reactors, and transformers.

      Low partial discharge effectively improves equipment insulation reliability.

2.Moderate mechanical strength and good toughness

      Wrinkle structure has good elasticity, stretch resistance, and is not easily brittle. It is not easily damaged during wrapping and assembly.

      Has a certain ability to withstand pressure and bending, meeting the requirements of coil support and insulation isolation.

3.Good heat resistance and high temperature aging resistance

      It belongs to Class A/E/B insulation and can work stably in an environment of 105 ℃ to 130 ℃ for a long time.

      Strong thermal stability, no softening, no delamination, and no release of harmful gases at high temperatures.

4.Strong adsorption and high oil absorption rate

      Paper with porous and wrinkled structure is oil friendly and quickly absorbs oil, which can fully adsorb transformer oil and form an oil paper composite insulation system, greatly improving the pressure resistance and heat dissipation ability.

5.Good chemical stability

      High purity, free of metal impurities and conductive ions, does not react with transformer oil, and does not corrode conductors.

      Resistant to moisture and aging, with a long service life.

6.Excellent processing and assembly performance

      Uniform texture, consistent thickness, easy to roll, cut, and fit in.

      The surface is flat, tightly adhered to the wire and iron core, and not easily loose.

7.Environmental Safety

      Natural plant fiber material, non-toxic and odorless, burns without toxic gases, meets the environmental protection requirements of electrical equipment.
