Descriptions
Class H (180ºC/220ºC)
Good mechanical properties
Du Pont Nomex® and Polyimide laminates
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.
