Precision Engineered Enameled Flat Wire for High-Efficiency Transformers
Shandong Huilong Electrical Material Co., Ltd., established in 1970 with over 50 years of expertise in electrical materials manufacturing, delivers premium enameled copper flat wire specifically engineered for transformer applications. Our 10,000-30,000 sqm ISO-certified facility combines advanced production capabilities with stringent quality control to provide wires that enhance energy transfer efficiency while minimizing eddy current losses. This 0.5mm x 2mm rectangular wire features optimized dimensional accuracy for compact winding designs, making it ideal for power transformers, inductors, and high-frequency applications.
Technical Specifications & Performance Advantages:
- Superior Conductivity: Oxygen-free copper core ensures minimal electrical resistance (typical conductivity: 101% IACS)
- Advanced Insulation: Triple-layer enamel coating provides exceptional dielectric strength (>8000V) and thermal endurance
- Dimensional Precision: Tight tolerance control (±0.01mm) enables consistent winding density
- Mechanical Durability: Withstands bending radius 3x wire thickness without insulation cracking
- Thermal Performance: Continuous operation at 180°C with Class H temperature rating
| Parameter | Value | Testing Standard |
|---|---|---|
| Conductor Cross-Section | 1.0 mm² | IEC 60317-13 |
| Insulation Thickness | 0.05mm ±0.005mm | IEC 60851-3 |
| Breakdown Voltage | Min. 8000V AC | IEC 60851-5 |
| Elongation at Break | ≥25% | ASTM B193 |
This flat wire configuration significantly reduces skin effect losses compared to round wires at high frequencies, while its rectangular profile allows up to 20% higher fill factor in winding slots. The uniform enamel coating ensures consistent inter-turn insulation resistance even under thermal cycling conditions, extending transformer service life. Custom spooling configurations and packaging are available to match automated winding equipment requirements.
