High-Temperature Resistant Enameled Flat Copper/Aluminum Wire from China Suppliers & Factory
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:
| Conductor Thickness (a) | 0.80 – 5.60 mm |
| Conductor Width (b) | 2.00 – 16.00 mm |
| Maximum Conductor Width Ratio | 20 : 1 |
🔶 Soft Copper Flat Wire
Adheres to GB5584.2-2009, with resistivity ≤ 0.017241 Ω·mm²/m at 20℃, available in three mechanical strength grades: C1 / C2 / C3.
🔷 Soft Aluminum Flat Wire
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:
