electrical insulation crepe paper/paper tube

electrical insulation crepe paper/paper tube

Electrical insulation crepe paper/paper tube has very good oil-soluble properties, and is widely used in oil-immersed transformers, instrument transformers, reactors and other parts of package insulation.

Description of Electrical Insulation Crepe Paper/Paper Tube

Electrical insulation crepe paper/paper tube is made of insulating kraft paper with creping.

Application of Electrical Insulation Crepe Paper/Paper Tube

Electrical insulation crepe paper/paper tube has very good oil-soluble properties, and is widely used 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.

Product Features of Electrical Insulation Crepe Paper/Paper Tube

1.Insulation class A (105 °C)

2.Color : natural brown, beige

3.High purity and high oil-absorption

4.Good dielectric strength

5.Excellent compatibility with insulating liquids (mineral oils, silicon oils and ascerol oils)

6.Free from conductive particles

Product Display of Electrical Insulation Crepe Paper/Paper Tube

Electrical insulation crepe paper/paper tube is one of the most important solid insulation materials used in transformers.

Its quality directly influences the life span of the transformer.

The BDV is enhanced by up to 80% as compared to base kraft paper.

To ensure of best quality of Crepe paper, the base kraft paper is manufactured using longer fibers of pure wood pulp.
