Electrical Grade Press Paper
Electrical grade press paper is a widely used insulation material in the power and electrical industry. Known for its excellent dielectric strength and mechanical stability, press paper is a core component of transformer and electrical insulation systems. ACC Insulations manufactures high-quality electrical grade press paper to meet stringent industrial requirements.
What Is Electrical Grade Press Paper?
Press paper is a dense, cellulose-based insulation paper manufactured by compressing high-purity wood pulp under controlled conditions. The process enhances mechanical strength and dielectric properties while maintaining oil compatibility.

Importance in Transformer Insulation
In transformers, kraft paper insulation:
- Separates conductors and windings
- Prevents short circuits
- Withstands electrical stress
- Maintains insulation integrity under heat
Inadequate quality of insulation paper may result in partial discharge and insulation failure as well as untimely transformer breakdown.
