Advantage:
AMA Aramid paper composite insulating materials has excellent heat-resistant, electrical, and mechanical properties. It is totally according with the standard of NMN (GB/T5591.3-2008), and it has the very similar property as NMN. It's perfect substitute of NMN.
Application:
AMA Aramid paper composite insulating materials is suitable for slot-to-slot insulation, phase-to-phase and turn-to-turn insulation of F-class motors, and can be used as interlayer insulation for transformers and other electrical appliance.
Notice:
1. During slitting and use, edge gaps and cracks should be prevented to avoid tearing during operation and to avoid surface scratches, oil and dust pollution.
2. Store in an environment below 40℃, keep clean and dry, away from heat sources, and avoid direct sunlight.
3. The storage period is one year. If it exceeds the storage period, it can still be used if it passes the test according to the technical requirements.
