Insulating Crepe Paper Widely Used in Oil-Immersed Power Transformers
Insulating crepe paper is pure wood pulp fiber, no additional adhesive, the first copy of Non-woven fabric caused by the pressure made of cardboard. Because of its high chemical purity, it is especially suitable for insulating materials used in motor and capacitor, especially in oil-immersed transformer. The high compactness and dimensional stability of the insulating crepe paper are ensured because of the special molding and pressing procedure used in its manufacturing process. It is also because of its good mechanical properties, it can also be processed into a transformer internal part of the fixed parts and spacing parts, in short circuit conditions, due to a good volume elasticity, can safely withstand the huge mechanical stress occurred in the transformer.
Because insulating cardboard products and plate mechanical strength and oil leaching performance is superior, now widely used in oil-immersed power transformers and distribution transformers. The insulating crepe paper has both mechanical and electrical characteristics after immersion, and this composite performance is not up to other insulating materials.
