High-Temperature Resistant Enameled Flat Copper/Aluminum Wire from China Factory - Trusted Suppliers
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 |
Adheres to GB5584.2-2009, with resistivity ≤0.017241 Ω·mm²/m at 20℃, available in three mechanical strength grades: C1 / C2 / C3.
Complies with GB5584.3-2009, with resistivity ≤0.02801 Ω·mm²/m at 20℃, ensuring efficient electrical conductivity.
Insulation thickness options include thin film (0.06–0.11 mm) and thick film (0.12–0.17 mm), while self-adhesive layers range from 0.03–0.06 mm, all monitored by professional dielectric loss meters. Key thermal performance highlights:
- QZY (180℃) — Exceptional heat resistance and heat shock resistance, suitable for high-temperature industrial equipment.
- Q(ZY/XY) (200℃) — Combines refrigerant and radiation resistance, ideal for harsh operating environments.
- QXY (220℃) — Superior chemical solvent resistance, maintaining stability in extreme conditions.
