This article will share with you the performance advantages of crepe kraft paper for insulation in transformer winding.
1. Inherent dielectric strength; The NOMEX insulated crepe paper product can withstand a short-time voltage of 18-40KV/mm, and the electric field distribution between the insulation and the cooling medium is uniform.
2. Mechanical toughness; NOMEX insulation crepe paper has very high mechanical strength, and good elasticity, tear resistance and corrosion resistance, thinner products have greater flexibility.
3. Thermal stability; NOMEX insulated crepe paper has an approved UL material temperature rating of 220 ° C, meaning it will remain effective at 220 ° C for more than 10 years.
4. Chemical compatibility; NOMEX crepe insulated paper is virtually unaffected by most solvents and is very acid and corrosion resistant.
5. Low temperature performance; NOMEX insulated crepe paper has sufficient tensile strength at the boiling point of nitrogen (77K).
6. Not sensitive to moisture; The dielectric strength of NOMEX insulating crepe paper remains 90% dry at 95% relative humidity, while many mechanical properties have been improved.
7. Radiation resistance; NOMEX insulating crepe paper maintains its own characteristics even at 800 MLD strength.
8. Non-toxic/fire resistant; NOMEX insulated crepe paper does not produce any known toxic reaction and does not melt in air with a critical air combustion value of 220 ° C.
