Electrical & mechanical performance:
Combines excellent electrical insulation with high mechanical strength; effectively withstands winding stress and resists breakage.
Dimensional stability:
Excellent dimensional stability with extremely low longitudinal and transverse shrinkage at 150°C.
Moisture resistance:
Non-hygroscopic and adapts well to various climatic conditions.
Thermal class:
Class F, ensuring long-term operational safety and reliability.
Main Insulation for Dry-Type Transformers:
Placed between the high-voltage and low-voltage coils, serving as the main insulating cylinder or barrier.
Inter-Turn and Spacer Insulation for Coils:
Used as inter-turn insulation or end spacer insulation during the coil winding process.
Motors and High-Voltage Electrical Apparatus:
Suitable for motor stator windings, high-voltage electrical equipment, and other insulation structures requiring high electrical strength.
Furthermore, this product is often used as a replacement for traditional epoxy resin boards or composite barriers containing non-woven fabrics, particularly in applications demanding high insulation strength and where material moisture absorption is undesirable.
