As an established magnet wire manufacturer since 1970, Shandong Huilong Electrical Material Co., Ltd. delivers premium polyurethane coated aluminum round wire engineered for demanding electrical winding applications. Our ISO-certified production facilities leverage decades of expertise to provide wires that combine exceptional electrical performance with mechanical durability. With over $100 million in annual exports to global markets including North America and Europe, we've refined this solution for reliability in motors, transformers, and electromagnetic devices.
Core Technical Advantages:
- Optimized Conductivity: Aluminum core reduces weight by 50% vs copper while maintaining efficient current transfer
- Superior Insulation: Polyurethane coating provides excellent dielectric strength (min 8kV/mm) and abrasion resistance
- Thermal Resilience: Available in 130°C, 155°C, and 180°C thermal classes for varied operating environments
- Winding Efficiency: Round profile ensures smooth feeding in automated winding machines with minimal coating damage
Technical Specifications:
| Parameter | Standard Range | Custom Options |
|---|---|---|
| Conductor Diameter | 0.1mm - 3.0mm | 0.05mm - 5.0mm |
| Film Build | Grade 1, Grade 2 | Triple coating available |
| Elongation | ≥15% | Up to 25% |
| Breakdown Voltage | Min 5kV | Up to 12kV |
This winding wire delivers tangible benefits including 30% weight reduction in rotating equipment, 20% lower material costs versus copper alternatives, and extended service life due to the coating's resistance to solvents and moisture. The flexibility of polyurethane allows tighter winding configurations without insulation cracking.
Frequently Asked Questions:
-
Q: What temperature range does this wire support?
A: Standard thermal classes include 130°C, 155°C, and 180°C options, suitable for most motor and transformer applications. -
Q: Can I get custom diameters outside standard ranges?
A: Yes, our production capabilities accommodate diameters from 0.05mm to 5.0mm with tight tolerance control (±0.005mm). -
