High-Frequency Litz Coil

Strong Product Adaptability

Our Huaying High-Frequency Litz Coil can withstand chemical corrosion and extreme operating conditions. First, let's talk about corrosion resistance. The coil's insulation is virtually insoluble in all organic solvents. It remains unaffected by harsh agents like oil, strong acids, and strong alkalis, making it ideal for complex environments like industrial workshops. Its electrical insulation performance is also excellent, with high-voltage resistance, low high-frequency loss, and low moisture absorption, resulting in consistently stable insulation resistance. Furthermore, even during the humid rainy season in southern China, the insulation resistance remains stable. More importantly, it's flame-retardant and aging-resistant. We've previously conducted aging tests for aerospace customers, and after 5,000 hours of continuous operation in high-temperature environments, the coils still performed like new, significantly extending their service life.

The product's winding process is meticulous

We've devoted considerable attention to the shape control of the Huaying High-Frequency Litz Coil, as shape inaccuracies directly impact high-frequency performance. Currently, we primarily use the external extrusion method to wind circular or oval coils. This method offers high wire alignment precision and uniform thickness across the coil. Extrusion, performed from the inner circle outward, ensures consistent coil conductivity, eliminating localized performance variations. We've also tried the internal extrusion method for square coils, but found that if the conductors aren't aligned properly, extrusion can easily damage them, impacting high-frequency performance. Furthermore, the machine structure becomes complex, costly, and inflexible if each layer is wound individually. Therefore, for high-frequency applications, we prioritize the external extrusion method to ensure precise coil shape without compromising performance. High-frequency coils require meticulous attention to detail. Even a slight angular deviation can lead to increased high-frequency losses, so we take no chances when it comes to shape control.

Strict Production Control

We maintain exceptionally strict quality control for Huaying High-Frequency Litz Coils, fearing that improper handling could affect performance. During winding, the ambient temperature and tension must be precisely set; arbitrary adjustments to meet production speeds are strictly prohibited. This ensures high-quality products. We also adhere to strict operating procedures during post-processing. For example, coils must be transported using dedicated trays; random stacking is prohibited, as this could damage the insulation during transport. The soldering temperature of the leads must be carefully controlled to prevent high temperatures from damaging the insulation. Each coil undergoes three stages of visual and performance testing to ensure no quality issues, ensuring peace of mind for our customers.
