NOMAX T410
Dupont FOMAX/NOMAX is a calendered insulation liner. Nomex® 410 is a family of insulation papers that offer high inherent dielectric strength, mechanical toughness, flexibilityand resilience. Nomex® 410, the original form of Nomex® paper, is widely used in a majority of electrical equipment applications. Available in 11 thicknesses ranging from 0.05 mm to 0.76 mm (2 mil to 30 mil), Nomex® 410 is used in almost every known electrical sheet insulation application.

Electrical Performance Performance Curve shows the typical electrical performance of NOMEX 410. The AC Rapid Rise dielectric strength data in Table I represent voltage stress levels withstood for 10 to 20 seconds at a frequency of 60 Hz. These values differ from long-term strength potential. |
Please Note: Data in the table are the typical data or average value, and can't be used as the technical specification. Unless otherwise stated, all data are measured under the "standard condition" (temperature: 23℃; relative humidity: 50%). Note: Similar to other paper products, the performance of NOMEX paper horizontal performance (MD) is different from its performance vertically (XD). In some application scenarios, the paper direction can be adjusted to utilize its optimal performance. |
