The difference between NMN insulation paper and NHN insulation paper

The main difference between NMN insulation paper and NHN insulation paper lies in their material composition, heat resistance grade, mechanical properties and uses.‌

1. Material composition and heat resistance grade

NMN insulation paper: It consists of a layer of polyester film and two layers of Nomex paper. And the heat resistance grade is F grade (155℃). Nomex paper is a high-performance aromatic polyamide material with excellent heat resistance and mechanical properties.

NHN insulation paper: It consists of a layer of polyimide film and two layers of Nomex paper. And the heat resistance grade is H grade (180℃). Polyimide film is a high-performance high-temperature resistant material with excellent mechanical strength and electrical properties.

2. Uses

Applications of NMN insulation paper

Medium and low voltage transformers: NMN insulation paper is widely used in turn-to-turn insulation and interlayer insulation of medium and low voltage transformers, providing good electrical performance and mechanical strength.

Motors and generators: NMN insulation paper is suitable for the insulation of small and medium-sized motors and generators, meeting the needs under medium temperature and environmental conditions.

Household appliances: NMN insulation paper is also widely used in household appliances (such as microwave ovens and electric ovens), providing reliable insulation protection.

Application of NHN insulation paper

High-voltage transformer: NHN insulation paper is suitable for turn-to-turn insulation and interlayer insulation of high-voltage transformers, providing excellent electrical performance and heat resistance.

High-temperature motors and generators: NHN insulation paper is suitable for motors and generators in high-temperature environments, meeting the needs under high temperature and high-voltage conditions.

3. Price and production process

In terms of price, NHN insulation paper is usually more expensive than NMN insulation paper because of its higher heat resistance, more complex material composition and better performance. However, the specific price is also affected by factors such as market supply and demand, product specifications, manufacturing process and brand. Therefore, when choosing insulating paper, we need to consider the price and cost factors besides its performance and application scenarios.

Future development trends

1. High-performance materials

Develop higher-performance insulation materials, such as new materials with low dielectric loss, high heat resistance and high mechanical strength. Promote environmentally friendly materials to reduce the impact on the environment.

2. Intelligent manufacturing

Integrate intelligent control systems to achieve intelligent manufacturing and optimized operation of insulation materials. Use big data and artificial intelligence technologies to optimize production processes and improve production efficiency and product quality.

3. Green manufacturing

Promote green manufacturing processes to reduce energy consumption and emissions in the production process. Improve the recyclability and reuse of materials to support the circular economy.

When choosing insulating paper, you should choose the appropriate type according to the specific application requirements and working environment. For electrical equipment that needs to withstand higher temperatures and mechanical stress, NHN insulation paper may be a better choice; while for some application scenarios that do not require high heat resistance and mechanical strength, NMN insulation paper can meet the needs and is lower in cost. At the same time, when choosing insulation paper, you also need to pay attention to factors such as its brand, specifications and manufacturing process to ensure its quality and reliability.
