6650 NHN Insulation Nomex Paper (NKN)

6650 NHN insulation paper also called NKN composite  is a composite insulation paper made of two layers of DuPont® Nomex® paper with one of polyimide film. It has good dielectric properties and mechanical properties, at high temperatures, and mechanical properties after being affected with damp are outstanding. 

NHN insulation paper is used when motor winding insulation needs higher heat resistance, good dielectric strength and stable mechanical performance.

Why NHN Is Used in Motor Insulation

Motor windings work under heat, voltage stress, vibration and mechanical pressure.

In high-temperature motors, ordinary insulation materials may not provide enough thermal margin.

NHN insulation paper is selected because it offers:

• Class H thermal resistance

• high dielectric strength

• good mechanical strength

• good flexibility

• stable insulation performance

• good slot insertion performance

• resistance to thermal aging

• reliable performance in high-temperature motor insulation systems

For motors working under higher temperature conditions, NHN is often a better choice than Class F composite insulation paper.

6650 NHN Insulation Paper Application

1. Motor Slot Insulation

NHN insulation paper is used as slot liner insulation between the stator core and winding.

It helps prevent electrical contact between the coil and metal core.

2. Phase Insulation

NHN can be used between different winding phases to improve insulation reliability.

3. Turn-to-Turn Insulation

For some winding structures, NHN can be used as turn-to-turn or layer insulation material.

4. Generator Insulation

Generators often require insulation materials with higher thermal stability.

NHN is suitable for generator winding insulation and related high-temperature electrical insulation parts.

5. High-Temperature Electrical Equipment

NHN insulation paper can also be used in transformers, coils, reactors and other electrical equipment where Class H insulation is required.

FAQ

Q1: Is NHN the same as Nomex paper?

A: No. NHN is not pure Nomex paper. It is a composite material. Nomex® is a well-known aramid paper brand, while NHN uses aramid paper and polyimide film in a laminated structure.

Q2: What is the difference between NMN and NHN insulation paper?

A: NMN uses PET film as the middle layer and is commonly used for Class F insulation. NHN uses polyimide film and is used for Class H insulation.

Q3: What is NHN insulation paper used for?

A: NHN insulation paper is used for motor slot insulation, phase insulation, turn-to-turn insulation, generator insulation and other high-temperature electrical insulation applications.
