Dupont Nomex Paper Type 410

DuPont™ Nomex® paper Type 410 is an insulation paper which offers high inherent dielectric strength, mechanical toughness, exibility and resilience. Nomex® paper Type 410 is the original form of Nomex® paper, and is widely used in a majority of electrical equipment applications. Available in 11 thicknesses (0.05 to 0.76 mm) (2 to 30 mil), Nomex® paper Type 410 is used in almost every known electrical sheet insulation application. electrical properties The typical electrical property values for Nomex® paper Type 410 are shown in Table 1. The AC Rapid Rise dielectric strength data of Table 1, representing voltage stress levels, withstood 10 to 20 seconds at a frequency of 60 Hz. These values differ from long-term strength potential. DuPont recommends that continuous stresses in transformers not exceed 1.6 kV/mm (40 V/mil) to help minimize the risk of partial discharges (corona). The full wave impulse dielectric strength data shown in Table 1 are based on multiple sheets. These values are appropriate for the applications which employ these materials in such confgurations. Data based on single sheets of material are available upon request.
