High-Temperature Enameled Flat Copper/Aluminum Wire | China Suppliers & Factory for Industrial Applications
This enameled flat wire takes high-quality oxygen-free copper or electrical aluminum rod as raw materials, which are strictly processed through drawing and extrusion by specification-specific molds to ensure uniform conductor structure. Its primary application lies in the windings of electrical equipment that demand stable operation at elevated temperatures, including heavy-duty transformers, high-frequency reactors, and industrial inverters. Based on the insulation paint formulation, it is categorized into six core types to match different thermal requirements:
- 120℃ Polyvinyl Acetal / Self-adhesive Polyvinyl Acetal Enameled Flat Wire (QQ/QQN)
- 130℃ Polyester Enameled Flat Wire (QZ)
- 155℃ Modified Polyester Enameled Flat Wire (QZG)
- 180℃ Polyester Imide Enameled Flat Wire (QZY)
- 200℃ Polyester Imide / Polyamide-Imide Composite Enameled Flat Wire (Q(ZY/XY))
- 220℃ Polyamide Imide Enameled Flat Wire (QXY)
| Conductor Thickness (a) | 0.80 – 5.60 mm |
| Conductor Width (b) | 2.00 – 16.00 mm |
| Maximum Conductor Width Ratio | 20 : 1 |
