FEATURES AND BENEFITS
Nomex™ 410 offers high dielectric strength properties, mechanical toughness and high flexibility.
Nomex is most commonly used with varnishes and resins, as well as transformer oils.
Typical tape thicknesses used for wrapping conductor is 2 mil. Other thicknesses are available upon request.
Most common construction utilizes two tapes with 50% overlap. Minimum overall increase in insulations thickness for 2 mil tape utilizing two tapes is 7 mil, per NEMA MW 1000-2018. Typical is 8 mil increased in total build.
Dielectric breakdown of not less than 300 V/mil of the minimum thickness of paper covering one side or half the minimum increase in build, per NEMA MW 1000-2018.
WIRE EDGE CONDITIONS
Radius corner, fully rounded edge, round, and trapezoidal.
