Advantage:
Insulation crepe paper has very good oil-soluble properties, stable electrochemical index and high physical strength. Especially as lead parts of the insulation package, thereby improving the electrical insulation and mechanical properties of the product structure.
Application:
Insulation crepe paper is used as interturn insulation for coils of oil-immersed transformers and interlayer insulation of distribution transformers.
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.
