Advantages1. Inherent dielectric strength
The calendered Nomex insulation paper product is resistant to short-term voltage field strengths of 18 to 40 kV/mm without the need for varnish and resin for further processing; since NOMEX products have a low dielectric constant, the insulation and cooling medium are The electric field distribution is more uniform;
2. Mechanical toughness
The calendered NOMEX insulation paper is very strong, and has good elasticity, tear resistance and abrasion resistance, and the thinner product has flexibility;
3. Thermal stability
NOMEX insulation paper has a UL material temperature rating of 220 ° C, which means that even if it is continuously placed at 220 ° C, it can maintain effective performance for more than 10 years;
4. Chemical compatibility
NOMEX insulation paper is largely unaffected by most solvents and is very resistant to acid and alkali corrosion. It is easily compatible with all varnishes, adhesives, transformer fluids, lubricants and cold heading agents. In addition, NOMEX insulation paper is not damaged by insects, fungi and molds;
5. Low temperature performance
At the boiling point of nitrogen (77K), the tensile strength of NOMEX insulation paper T410 and NOMEX993, 994 laminates exceeds the strength value at room temperature;
6. Not sensitive to moisture
When the NOMEX insulation paper is 95% wet, its dielectric strength is 90% in the completely dry state, and at the same time, many mechanical properties are actually improved;
7. Radiation resistant
Even with an ionizing intensity of 800 megarads (8 mega-gray), NOMEX insulation paper is essentially unaffected and retains its mechanical and electrical properties after 8 such doses of radiation;
8. Non-toxic / flame resistant
NOMEX insulation paper does not produce any known toxic reaction to humans or animals. NOMEX insulation paper does not melt in the air, does not support combustion, and its oxygen limit index (LOI) is greater than 20.8 at 220 ° C (general empty combustion criticality) Value), so it will not burn. Nomex insulation paper meets the flame resistance requirements of UL94V-0"
