Why Grade 2?
- Enhanced dielectric strength for high-voltage windings
- Improved moisture & chemical resistance
- Superior mechanical abrasion during coil winding
- Longer service life in hermetic compressor motors
- Reduced risk of pinholes & insulation failure
- Direct fit for automated winding lines
|
⚡ Grade 2 (Heavy Build) Advantage: Compared to Grade 1 or thinner builds, QZY-2/180 provides approximately 30% higher breakdown voltage and superior resistance to thermal cycling. It is the industry-preferred choice for transformers, industrial motors, and automotive applications where reliability is critical.
Precision Engineered for Demanding Environments
CHINGCUNG QZY-2/180 features a dual-coated polyesterimide insulation that delivers exceptional thermal endurance at 180°C continuous operation. The Grade 2 build provides a robust dielectric barrier, making it ideal for inverter-duty motors, sealed compressors, and traction systems. Unlike polyurethane wires (QA series), QZY maintains structural integrity under high-temperature overload and refrigerant exposure.
Our advanced manufacturing process ensures uniform coating thickness, low friction coefficient, and excellent adherence. Each batch undergoes rigorous testing: dielectric breakdown, heat shock, scrape resistance, and continuity. With over 10 years of specialized production experience, CHINGCUNG guarantees consistent quality across all diameters.
Primary Applications for QZY-2/180
Hermetic Compressors, HVAC Fan, Motors, Power Tools, Dry-Type Transformers, Automotive Alternators, Pump Motors, Industrial Drives, Induction Heating Coils
