In modern electrical systems, insulation materials are no longer just about electrical isolation — they play a critical role in thermal management, mechanical stability, and long-term reliability.
Class H NHN Insulation Paper (180°C) is specifically engineered for high-temperature motor and transformer applications, offering a balanced combination of thermal endurance, dielectric strength, and processing flexibility.
NHN insulation paper is a three-layer composite material made of:
Outer layers: Nomex Paper
Inner layer: PET (Polyester Film)
This structure combines the excellent heat resistance of Nomex with the mechanical strength and dielectric properties of PET, resulting in a high-performance insulation laminate.
Key Features of Class H NHN (180°C)
High Thermal Resistance
Designed for Class H insulation systems, NHN can withstand continuous operating temperatures up to 180°C, making it ideal for demanding environments.
Dielectric Strength
The PET core provides high electrical insulation performance, ensuring safety and reliability in high-voltage applications.
Strong Mechanical Stability
NHN maintains its structural integrity under mechanical stress, vibration, and thermal aging.
Excellent Processability
• Easy to slit, cut, and die-cut
• Suitable for automated production lines
• Applications in Motor & Transformer Industry
Electric Motors
• Slot insulation
• Phase insulation
• Winding wrapping
• Interlayer insulation
