Enamelled Wire for Automotive Solenoids With 220V Insulation Rating
Product Spotlights
With over 50 years of expertise in electrical materials manufacturing, Shandong Huilong Electrical Material Co., Ltd. delivers premium enamelled wire engineered specifically for automotive solenoids. Our ISO-certified production facility spanning 10,000-30,000㎡ combines traditional craftsmanship with advanced technology to produce wires that meet rigorous automotive industry standards. The 220V insulation rating ensures operational safety in high-voltage environments while maintaining consistent performance across temperature fluctuations.
Core Technical Specifications:
| Parameter | Value | Testing Standard |
|---|---|---|
| Dielectric Strength | ≥8000V/mm | IEC 60317-0-1 |
| Thermal Endurance | 20,000+ hours @155°C | IEC 60172 |
| Elongation at Break | ≥15% | ASTM B193 |
Performance Advantages:
- √ Vibration-resistant construction maintains insulation integrity in high-shock automotive environments
- √ Chemical compatibility with epoxy potting compounds and varnishes
- √ Tight tolerance control (±0.002mm) ensures consistent winding density
- √ Optimized space factor reduces solenoid size by up to 18%
This specialized winding solution delivers three critical benefits for solenoid manufacturers: extended product lifecycle through superior thermal aging resistance, reduced warranty claims via enhanced dielectric stability, and improved manufacturing yield from consistent mechanical properties. The triple-layer enamel coating provides exceptional pinhole protection even at minimum bend radii.
Customization Options:
- Custom spooling configurations (traverse-wound, layer-wound)
- Specialized packaging for automated feeding systems
- Color-coding options for production traceability
- UL-recognized variants available
Backed by our $100M+ annual export volume and IATF 16949 certification, we guarantee material traceability through full manufacturing documentation. With warehouses near Qingdao, Shanghai, and Ningbo ports, we maintain 30-day inventory of standard gauges for rapid shipment to North American, European, and Southeast Asian markets. Our technical support team provides application-specific guidance on winding parameters and thermal management.
