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.Crepe Paper Tubes
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.Crepe Paper Tubes
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.
In the oil-immersed transformer, of course, to use the insulating crepe paper, but must ensure that the quality of insulating crepe paper better. The insulating wrinkle paper can be used for the main insulating clapboard, the interlayer insulation in foil or the plate-like conductor, the lead insulation of the low-voltage or high-voltage lead wires, and the insulated or insulated insulation from the burning group to the casing or other terminals; insulation of the rectangular electromagnetic wire, In a large power transformer with liquid insulation, this kind of electromagnetic wire is often used in paper base insulation, which is usually used less in distribution transformers, and in particular requires the insulation of soft bending parts.Crepe Paper Tubes
The product has the UL material temperature level 220 degree approval, the representative even if continuously puts on 220 degrees to be able to maintain the validity can more than 10 years. Product strength is high, and the elasticity of the tear resistance and abrasion resistance are good, the thinner product is flexible. It is largely unaffected by most solvents and is very resistant to acid and alkali corrosion, and is compatible with all varnishes, adhesives, transformer liquids, lubricants and freezers, and is not destroyed by insects, fungi and molds.

Even if the intensity of the ionization is up to 800 MPA, the product is largely unaffected, and after 8 of such doses of radiation it retains its mechanical and electrical properties.Crepe Paper Tubes
