Customizable Enameled Flat Wire for Electrical Equipment - Top China Suppliers & Factory
Designed for versatility, this enameled flat wire is fabricated from high-purity oxygen-free copper or electrical aluminum rod, processed by drawing and extrusion with molds tailored to specific dimensions. It is widely used in the windings of various electrical equipment, including power transformers, distribution reactors, and electronic inverters, providing reliable insulation and conductive performance. Based on the type of insulating paint, it is divided into six categories to cover different application scenarios:
- QQ / QQN — 120℃ Polyvinyl Acetal / Self-adhesive Polyvinyl Acetal Enameled Flat Wire
- QZ — 130℃ Polyester Enameled Flat Wire
- QZG — 155℃ Modified Polyester Enameled Flat Wire
- QZY — 180℃ Polyester Imide Enameled Flat Wire
- Q(ZY/XY) — 200℃ Polyester Imide / Polyamide-Imide Composite Enameled Flat Wire
- QXY — 220℃ Polyamide Imide Enameled Flat Wire

🏅Hengte Electric, an ISO9001:2015 certified manufacturer, offers full customization based on customer technical drawings or specifications. All products have obtained SGS, UL, and CE certifications, guaranteeing quality and compliance. Whether you need specific thermal grades, conductor dimensions, or insulation properties, we can tailor the product to your exact requirements.
Hengte Electric offers six insulation categories of enameled flat wire: QQ/QQN (120℃), QZ (130℃), QZG (155℃), QZY (180℃), Q(ZY/XY) (200℃), and QXY (220℃). Each category is designed for specific thermal grades and application scenarios, from standard power transformers to high-performance industrial inverters.
The enameled flat wire is available in two conductor materials: high-purity oxygen-free copper (compliant with GB5584.2-2009) and electrical-grade aluminum (compliant with GB5584.3-2009). Copper offers superior conductivity, while aluminum provides a cost-effective alternative without significantly compromising performance.
Yes. Conductor thickness (a) ranges from 0.80 mm to 5.60 mm and conductor width (b) ranges from 2.00 mm to 16.00 mm. Both dimensions can be tailored to your specific requirements. Insulation film thickness is also selectable between thin film (0.06–0.11 mm) and thick film (0.12–0.17 mm), giving you full control over the product profile.
All enameled flat wire products manufactured by Hengte Electric have obtained SGS, UL, and CE certifications. The company itself is ISO9001:2015 certified, ensuring consistent quality management and production processes. Products also conform to GB/T 7095 series and IEC 60317 international standards.
This enameled flat wire is widely used in the windings of electrical equipment such as power transformers, distribution reactors, and electronic inverters. Its range of thermal grades (120℃ to 220℃) and customizable dimensions make it suitable for both standard industrial applications and demanding high-temperature environments.
Each product undergoes rigorous testing in accordance with GB/T 4074 and IEC 60851 standards. Tests include breakdown voltage, scratch resistance, thermal endurance, and solvent resistance. These stringent quality checks ensure that every batch of enameled flat wire meets the required insulation performance and safety specifications before shipment.
