Customizable Enameled Flat Wire for Electrical Equipment by China Suppliers and Factory - Ideal for Windings
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
