Customizable Enameled Flat Wire for Electrical Equipment Windings - China Suppliers & Factory Quality
Product Information
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

❓ Frequently Asked Questions
What materials are used in the construction of enameled flat wire?
The enameled flat wire is fabricated from high-purity oxygen-free copper or electrical-grade aluminum rod. The conductor is drawn and extruded with precision molds, then coated with insulating enamel paint in grades ranging from 120℃ to 220℃ depending on the application requirement.
What thermal grades are available for enameled flat wire?
Six thermal grades are available: QQ/QQN (120℃), QZ (130℃), QZG (155℃), QZY (180℃), Q(ZY/XY) (200℃), and QXY (220℃). Each grade is formulated with specific insulating paints to meet different operating temperature requirements.
Can the conductor dimensions be customized?
Yes. Conductor thickness (a) can be adjusted from 0.80 mm to 5.60 mm, and conductor width (b) from 2.00 mm to 16.00 mm. Custom width ratios and insulation thicknesses (thin film or thick film) are also supported based on customer technical drawings or specifications.
What international certifications does the product comply with?
All enameled flat wire products meet GB/T 7095 series and IEC 60317 standards for insulation performance. Testing follows GB/T 4074 and IEC 60851 protocols. The manufacturer, Hengte Electric, is ISO 9001:2015 certified, and products carry SGS, UL, and CE certifications.
What are the typical applications of enameled flat wire?
Enameled flat wire is widely used in the windings of power transformers, distribution reactors, and electronic inverters. Its flat profile allows for higher fill factors in coil winding, making it ideal for high-efficiency electrical equipment requiring compact, reliable insulation.
What is the resistivity performance of copper vs. aluminum conductors?
Copper conductors conform to GB5584.2-2009 with resistivity ≤0.017241 Ω·mm²/m at 20℃, offering superior conductivity. Aluminum conductors comply with GB5584.3-2009 with resistivity ≤0.02801 Ω·mm²/m at 20℃, providing a cost-effective alternative while maintaining reliable electrical performance.
