QZY-2/180 Polyesterimide Enameled Copper Wire Optimized for Motor Windings, Transformers & Coils - High Heat & Voltage Resistance

QZY-2/180 Polyesterimide Enameled Copper Wire
Class 180 (H) · Grade 2 Heavy Build

 Grade 2 insulation thickness | Superior dielectric strength | Optimized for motor & transformer windings 

⚡ 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
