DuPont™ Nomex® LT is a new nonwoven material developed specifically for use in Class F and H (180°C or less) electrical insulation systems. Based on decades of experience and unique testing capabilities, DuPont™ Nomex® and nonwovens scientists collaborated to develop this new patented electrical insulation material. Nomex® LT is a cost effective, strong and tear-resistant material with excellent resin and varnish saturability. These properties allow electrical designers new alternatives to optimize designs for Class H and below motors, generators and dry-type transformers.
Nomex® LT is available in discrete and laminate forms in thicknesses from 2.5 to 10.0 mils. It can be used as conductor wrap and phase and layer insulation for coils where flame resistance is not required. Its high mechanical strength allows manufacturers to use thinner sheets of Nomex® LT to obtain the same performance as with other insulation materials in Class F and H systems.
