Advantage:
NMN polyester film polyarylamide composite insulation paper has good flexibility, excellent mechanical strength, dielectric properties, tear strength and varnish absorption capacity.
Application:
NMN polyester film polyarylamide composite insulation paper is suitable for inter-slot insulation, liner insulation and turn-to-turn insulation of motors and special motors, and can also be used as interlayer and interval insulation of dry-type transformers and reactors.
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.
