As an ISO-certified manufacturer since 1970, Shandong Huilong Electrical Material Co., Ltd. delivers premium Dual-Coated Polyurethane/Polyamide Enameled Copper Wire (UEW-N/155) from our 30,000 sqm facility. With over $100M annual exports to 15+ global markets including North America and Europe, our wires combine decades of expertise with rigorous quality control. The dual-layer insulation provides exceptional dielectric strength while maintaining flexibility – ideal for demanding electromechanical applications.
Core Technical Advantages:
- Dual-coat architecture enhances chemical resistance and mechanical durability
- Polyamide underlayer improves adhesion while polyurethane topcoat ensures flexibility
- Thermal Class 155 rating withstands continuous high-temperature operations
- Reduced dielectric losses increase energy efficiency in windings
Key performance parameters include:
| Property | Standard Value | Benefit |
|---|---|---|
| Breakdown Voltage | ≥8 kV/mm | Prevents short circuits |
| Elongation | 30-35% | Resists winding stress |
| Thermal Shock | No cracks at 200°C | Ensures thermal stability |
This wire enables manufacturers to achieve:
- 15% longer service life in hermetic compressors
- Reduced winding failures in humid environments
- Compatibility with automated coil winding machines
