Products Description
Flexible Composite Insulation Paper NHN is a three-layer flexible composite insulation material made of two layers of Nomex paper and one layer of polyimide film. It has excellent high temperature resistance (H grade, 180°C), electrical insulation performance and mechanical strength. It is particularly suitable for electrical equipment that requires high temperature stability and reliability, such as H-class motors, dry-type transformers, high-frequency power supplies, etc.
Flexible Composite Insulation Paper Structure: Nomex paper + polyimide film + Nomex paper
Note：We also offer AHA, which is composed of domestically produced aramid paper and polyimide film.
Insulation grade: H grade
Heat resistance: ≥180 degrees Celsius
Thickness: 0.15mm-0.25mm
