Class F DMD Insulation Paper Sold to Indonesia

The Challenge: Class B Insulation Falling Short

Our client in Indonesia was previously using Class B (130°C) DMD insulation paper for their standard industrial motors. However, as they expanded their product line to include high-performance motors for more demanding environments, they encountered a critical issue: insufficient heat resistance.

During rigorous testing, the Class B insulation showed signs of premature thermal aging, leading to a higher risk of motor failure. The client needed a solution that could withstand higher temperatures without significantly increasing their production costs.

The Consultation: Why Upgrade to Class F DMD?

After several rounds of technical discussions via video calls and email, our engineering team analyzed the client's motor specifications and operating conditions. We identified that the motors were frequently operating near the thermal limit of Class B materials.

We proposed a strategic upgrade to Class F (155°C) DMD insulation paper. Here’s why we recommended this specific solution:

•Superior Thermal Stability: Class F DMD offers a 25°C higher temperature threshold than Class B, providing a crucial safety margin for high-performance motors.

•Mechanical Integrity: Our Class F DMD maintains excellent tensile and tear strength even at elevated temperatures, ensuring the integrity of the motor winding.

•High Cost-Effectiveness: While Class F is a premium grade, our optimized manufacturing process allows us to offer it at a price point that provides exceptional value compared to more expensive alternatives like NMN or NHN.

The Solution: Implementation and Testing

We provided the Indonesian client with several rolls of our 6641-F DMD insulation paper for initial sampling and testing. Our technical team guided them through the winding and impregnation process to ensure optimal compatibility with their existing resins.

The results were outstanding. The motors equipped with our Class F DMD passed all thermal endurance tests with flying colors, showing significantly improved reliability and a longer projected lifespan.

The Result: A Long-Term Partnership

Impressed by the performance and our professional technical support, the client placed a bulk order for their entire new motor series. By upgrading to Class F DMD, they were able to:

1.Enhance Product Reliability: Eliminate thermal aging issues and reduce warranty claims.

2.Improve Market Competitiveness: Offer high-performance motors that meet international standards.

3.Optimize Costs: Achieve superior insulation performance without the prohibitive costs of H-class materials.

"Chengrui didn't just sell us paper; they provided a solution. Their recommendation to switch to Class F DMD was exactly what we needed to take our motors to the next level." — Production Manager, Indonesian Motor Factory
