Customizable Enameled Flat Wire from China Suppliers - Precision-Made for Electrical Equipment Winding at Our Factory
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
Q
What conductor materials are available for the enameled flat wire?
The enameled flat wire is available in two conductor materials: high-purity oxygen-free copper and electrical-grade aluminum rod. Copper offers lower resistivity (≤0.017241 Ω·mm²/m at 20℃) for maximum conductivity, while aluminum provides a cost-effective alternative with a resistivity of ≤0.02801 Ω·mm²/m at 20℃.
Q
What temperature grades are available for the insulation?
Six thermal grade options are available: 120℃ (QQ/QQN – Polyvinyl Acetal), 130℃ (QZ – Polyester), 155℃ (QZG – Modified Polyester), 180℃ (QZY – Polyester Imide), 200℃ (Q(ZY/XY) – Composite), and 220℃ (QXY – Polyamide Imide). Each is designed to suit different operating environments and application requirements.
Q
Can the conductor dimensions be customized?
Yes. The conductor thickness (a) can be produced in the range of 0.80–5.60 mm, and the conductor width (b) from 2.00–16.00 mm. Insulation thickness can also be specified as either thin film (0.06–0.11 mm) or thick film (0.12–0.17 mm) depending on your application needs. Custom dimensions based on technical drawings or specifications are fully supported.
Q
What international certifications does this product hold?
All enameled flat wire products from Hengte Electric have been certified by SGS, UL, and CE, and the manufacturing facility holds ISO 9001:2015 certification. The products also comply with GB/T 7095 series and IEC 60317 insulation standards, and undergo testing per GB/T 4074 and IEC 60851 for breakdown voltage, scratch resistance, and solvent resistance.
Q
What are the typical applications for enameled flat wire?
Enameled flat wire is widely used in the winding coils of power transformers, distribution reactors, and electronic inverters. Its rectangular cross-section allows for higher fill factors and more compact winding designs compared to round wire, making it ideal for high-efficiency electrical equipment.
Q
Does Hengte Electric support OEM or custom orders?
Yes. Hengte Electric offers full OEM and custom manufacturing services. Customers can provide technical drawings or detailed specifications, and the team will produce enameled flat wire tailored to the exact thermal grade, conductor material, dimensions, and insulation properties required.
