Insulating Crepe Paper That is Not Afraid of the Passing of Time
Insulating crepe paper is pure wood pulp fiber. No additional adhesive is added. The cloth is first copied into a non-woven fabric and then pressed into cardboard. Due to its high chemical purity, the paperboard is particularly suitable for use as an insulating material in motors and capacitors, especially in oil-immersed transformers.
Due to the use of special molding and pressing procedures in its manufacturing process, high density and dimensional stability of the insulating crepe paper are ensured. Because of its good mechanical properties, it can also be processed into the fixed part and the spacing part of the live part of the transformer. Under the condition of short circuit, due to the good volume elasticity, it can safely withstand the huge mechanical stress occurring in the transformer.
Because of the mechanical strength and excellent oil leaching performance of insulating paperboard products and sheets, they have been widely used in oil-immersed power transformers and distribution transformers. Insulating crepe paper has both mechanical and electrical characteristics after immersion, and the properties of this composite are not achieved by other insulating materials. It is inherently very acid and alkali resistant. It is also compatible with all varnishes, adhesives, transformer fluids, lubricants and freezers, and is not damaged by insects, fungi and mold.
