Product Description

1.This product is made in a rolled process with electrical crepe paper and mainly used in oil-immersed transformer as insulation wrapping.

Insulation class A (105 °C)

2.Characteristics: Insulation Crepe Paper is one of the most important solid insulation materials used in transformers, it is multi layers of electrical grade crepe and kraft paper for insulating leads in oil-immersed  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. In order to make sure the quality of Crepe paper is  the best, the base kraft paper is manufactured using longer fibers of pure wood pulp.

3.Usage: It has excellent electrical properties, used for wire, transformer insulation and internections.

4.Spec.: Standard base paper thickness: 0.05mm, 0.08mm & 0.13mm

Pipe Diameters: Ф4*Ф8*1000/Ф8*Ф14*1000/Ф10*Ф20*1000 (The product’s diameter are negotiable.)
