Advantage:
PMP Double-sided insulation paper polyester film composite has good dielectric properties and high mechanical strength.
Application:
PMP Double-sided insulation paper polyester film composite is suitable for all kinds of high voltage transformers as gasket insulation.
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.
