DuPont insulating paper, motor insulating paper, Liaobu insulating paper, Dongguan motor insulating paper, transformer insulating paper, DuPont series insulating paper is the raw material of insulating paper. Due to its ideal balance of characteristics and mature and stable performance in a wide range of applications, It is well received worldwide. Over the years, it has met the growing requirements of the electrical industry and is the insulating material used in most electrical equipment applications today. The best-known insulating paper in the range is today a classic benchmark product in terms of performance, reliability and longevity, a benchmark against which all other insulation materials are compared. The outstanding properties of the product, as well as those of other products in the series, result from an ideal balance of five key properties: Excellent thermal stability—temperatures up to °C have no or minimal effect on the electrical and mechanical properties, even at considerably higher temperatures Still maintain use value. Furthermore, these excellent characteristics are maintained even when exposed to °C environments for at least several years of continuous operation. ?Excellent mechanical toughness—Reinforced products are strong and resilient while resisting tear and abrasion. Thinner grades also offer flexibility. ?Inherent dielectric strength - In reinforced products, the ability to withstand electrical stresses of / to / (, ) for short periods of time without the need for painting or resin treatment, depending on the type and thickness of the product. ?Broad chemical compatibility—essentially unaffected by most solvents and unusually resistant to attack by acids and alkalis. It is compatible with all types of paints and adhesives, transformer oils, lubricants and refrigerants. ?Excellent flame retardancy - the product will not melt and will not burn when the limiting oxygen index exceeds .(usually the critical value for combustion in air). Used in nearly all sheet insulation applications. This high-density product offers inherently high dielectric strength, mechanical toughness, flex resistance and recovery capabilities. The thickness of its products ranges from . to , and the specific gravity ranges from . to . Yes low density version. Its thickness ranges from . to . and has a specific gravity of .3 and correspondingly lower electrical and mechanical properties. It is used in applications such as motor phase insulation and transformer winding end insulation where high porosity and consistency, as well as high stability and saturation are important. The electrical properties and thermal properties are similar to , however it is used to produce a strong but more flexible and consistent sheet with an exposed surface. The thickness of its products ranges from . to . ( ), and the specific gravity ranges from . to . This material is designed for slot insulation in hand-wound motors, linear cable wraps, and main insulation in dry-type transformers where consistency and stability are important. is an insulating paper designed for use in electrically flexible laminate insulation. Its products are available in three thicknesses: . ( ), . and . ( ). Base laminates are used to create high-integrity electrical insulation materials used in motors, generators and transformers. There are a variety of laminate constructions. The most common structures are AND (using insulating paper and polyester film) and OR (using insulating paper and polyimide film). Comparison is a lightweight insulating paper, but is also used in the same electrically flexible laminate insulation applications. Thicknesses provided are . ( ). Similar laminated structures are available on the market, using polyester or polyimide films depending on the heat resistance requirements of the application. Typical applications of the series - High power, medium and high voltage (>. ) - Medium voltage, general purpose (>. ) - Medium voltage, substation (>. ) - Low voltage, general/special purpose (
