Products Information

6650 NHN INSULATION PAPER
 NHN/NKN (Nomex paper/Polymide film/Nomex paper)is a Triple layer electrical insulation material of thermal class  H 180ºC, consisting of polymide film covered with Du Pont Nomex paper. The polymide film giving the product mechanical and dielectric features, while the Du Pont Nomex paper gives the thermal resistance.This NHN has excellent electrical.mechanical,and impregnating properties.

Applications
Combined flexible materials NHN applications:
Composite insulation material NHN has good electrical and mechanical properties of dielectric, under high temperature and wet mechanical properties especially;Used for H level motors, electrical appliances slot insulation, turn insulation, liner and H level dry transformer insulation between the layer insulation, etc..
Class H (180ºC/220ºC)
Good mechanical properties 
Du Pont Nomex®  and Polyimide laminates

General description
 NHN  is a 3-ply flexible laminate made of Nomex® paper-Polyimide film-Nomex® paper bonded with a synthetic adhesive.The total thickness fo the product is decided of the thickness of Nomex® paper,also the properties.
 
Application
 NHN is suitable for insulation in electrical motors and transformers with a maximum operating temperature of 180ºC. It is used in low or medium voltage rotating machines as ground and slot insulation. It can be used as well as intermediate layer in transformers.
