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

1What 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 conductors offer lower resistivity and superior conductivity, while aluminum conductors provide a cost-effective alternative with balanced performance.
2What are the available thermal class grades for the insulation?
Six thermal class grades are available: 120℃ (QQ/QQN), 130℃ (QZ), 155℃ (QZG), 180℃ (QZY), 200℃ (Q(ZY/XY)), and 220℃ (QXY). Each grade uses a specific insulating varnish formulation suited to different operating environments and application requirements.
3Can the conductor dimensions be customized to specific requirements?
Yes. Conductor thickness can range from 0.80 mm to 5.60 mm, and conductor width from 2.00 mm to 16.00 mm. Custom dimensions and width-to-thickness ratios are supported. Customers can provide technical drawings or specifications, and the product will be manufactured accordingly.
4What international certifications does the product hold?
All products have obtained SGS, UL, and CE certifications. The manufacturing facility is ISO 9001:2015 certified, ensuring consistent quality management. Products also comply with GB/T 7095 series and IEC 60317 international standards for enameled winding wires.
5What applications is this enameled flat wire suitable for?
This enameled flat wire is widely used in the windings of electrical equipment such as power transformers, distribution reactors, and electronic inverters. Its combination of reliable insulation, precise dimensions, and high conductivity makes it suitable for both industrial and commercial electrical applications.
6What quality tests are performed on the enameled flat wire?
Each product undergoes strict testing in accordance with GB/T 4074 and IEC 60851 standards. Key tests include breakdown voltage testing, scratch resistance evaluation, and solvent resistance assessment. These tests ensure the wire meets the required insulation integrity and mechanical durability for demanding electrical applications.
