As a leading manufacturer since 1970, Shandong Huilong Electrical Material leverages its 10,000-30,000 sqm facility and ISO-certified production to deliver premium enamelled copper wire engineered specifically for automotive solenoids. Our precision-wound wire ensures optimal magnetic field generation and consistent performance in critical vehicle components like fuel injectors, starters, and transmission systems.
Core Technical Advantages:
- Precision winding tolerance <±0.5% minimizes eddy current losses
- Uniform enamel coating with dielectric strength >8kV/mm
- Thermal endurance at 180°C continuous operation (Class H rating)
- Reduced skin effect through controlled conductivity properties
| Property | Specification | Benefit |
|---|---|---|
| Conductivity | ≥101% IACS | Enhanced energy efficiency |
| Elongation | 15-35% (adjustable) | Resistance to winding stress |
| Adhesion | Grade 1 (excellent) | Prevents insulation cracking |
The triple-layer polymer insulation provides exceptional chemical resistance against automotive fluids while maintaining flexibility across temperature extremes. Our proprietary manufacturing process eliminates pin holes, ensuring dielectric integrity even in high-vibration environments.
With over 50 years of metallurgical expertise and annual exports exceeding $100M to 14 global markets including North America and Western Europe, we guarantee batch-to-batch consistency. Our Qingdao/Shanghai/Ningbo ports enable efficient logistics for OEMs and Tier-1 suppliers requiring AS9100-compliant materials.
