CHINGCUNG® Special Enameled Wire Expert
Premium Grade 1 – High-Thermal Polyurethane Enameled Copper Wire
Superior thermal endurance for demanding applications — compact windings, automotive systems, power tools & high-temp transformers.
Why QA-1/180 Grade 1?
Grade 1 construction ensures minimum insulation film thickness for increased winding density and space-saving designs. With thermal class 180°C, it provides higher heat resistance than standard class 155 wires, while maintaining direct solderability and excellent flexibility. Perfect for applications exposed to elevated temperatures.

Note: Grade 1 reduces outer diameter by approx. 20-30% compared to Grade 2, enabling compact coil designs and better heat dissipation. Data based on IEC 60317-51 standard. For ultra-fine diameters (<0.10mm) please contact our technical team.
Product Overview & Core Features
CHINGCUNG QA-1/180 enameled copper wire is engineered for high-temperature environments where standard polyurethane wires may not suffice. The advanced polyurethane insulation provides exceptional thermal stability up to 180°C, while the Grade 1 film thickness guarantees maximum copper space factor. This wire combines high-heat performance with outstanding electrical properties, making it the go-to choice for compact, high-power-density windings.
✦ Key engineering advantages: Direct solderability without pre-stripping reduces assembly time and cost. The modified polyurethane varnish offers excellent resistance to refrigerants, oils, and moisture, making it ideal for hermetic motors and automotive under-the-hood applications. QA-1/180 also passes rigorous mandrel wrap and elongation tests, ensuring no insulation cracking during high-speed winding.
✦ Quality commitment: Each batch is 100% tested for pinholes, continuity, and breakdown voltage. Our ISO-certified labs perform regular thermal aging, heat shock, and cut-through tests to guarantee compliance with IEC and NEMA standards. As a specialized enameled wire manufacturer, we offer full traceability from copper rod to final spool.
