Avoid keeping insulating paper in high-temperature environments, as every 8°C increase in ambient temperature halves its lifespan.

2. Ensure to avoid exposure to light and radiation, as they can alter the molecular structure of insulation, thereby reducing its strength.

3. Avoid corrosive chemicals gases or liquids as they can alter the insulating paper's insulating properties, reducing its strength.

4. During transportation, clean conveyance tools with preventive measures must be used and should not be transported with contaminated materials; when handling and stacking, insulating paper should not be dropped from high places.

5. Insulating paper should be properly stored to prevent damage from rain, snow, ground moisture, acids, alkalis, and chemical gases. The usage environment should maintain daily cleanliness.
