Insulation paper is a fundamental insulating material for transformer windings, providing electrical isolation and thermal resistance between conductors to ensure the transformer's long-term safe operation.
Key Features
- High Thermal Resistance: Available in Class B (130℃) and Class H (180℃) ratings, with NOMEX® paper offering Class C (220℃) performance for high-temperature applications.
- Excellent Mechanical Strength: Resists tearing, puncture, and compression, maintaining integrity under short-circuit forces and thermal expansion.
- Superior Dielectric Properties: High breakdown voltage and low dielectric loss, ensuring reliable insulation even in harsh conditions.
- Chemical Stability: Resists moisture, oil, and chemical corrosion, extending the transformer's service life.
Applications
Used in the manufacturing of dry-type and oil-immersed transformer windings, as well as in capacitors, motors, and other electrical equipment requiring high insulation performance.
