As a leading manufacturer since 1970, Shandong Huilong Electrical Material Co., Ltd. presents our premium 200°C Heat-Resistant Enameled Copper Magnet Wire engineered specifically for solar inverter transformers. With over 50 years of expertise in electrical materials and ISO9001-certified production processes, we deliver wires that ensure exceptional thermal stability and electrical performance in demanding renewable energy applications. Our commitment to quality has established us as a trusted supplier to global markets across North America, Europe, and Asia-Pacific regions.
Core Technical Specifications:
| Property | Value |
| Conductor Material | High-purity Copper (99.99%) |
| Thermal Class | 200°C (Class H) |
| Dielectric Strength | >8kV/mm |
| Elongation at Break | >30% |
Key Advantages:
- Enhanced Thermal Endurance: Withstands continuous 200°C operation and short-term peaks up to 240°C, preventing insulation breakdown in high-temperature transformer environments
- Optimized Electrical Performance: Uniform enamel coating ensures minimal dielectric losses and improved efficiency in power conversion systems
- Mechanical Durability: Superior flexibility and abrasion resistance during winding processes, reducing production waste
- Corrosion Resistance: Special enamel formulation protects against moisture and chemical degradation in diverse operating environments
Applications in Solar Energy Systems:
- High-frequency transformers in grid-tie inverters
- DC-DC converters in photovoltaic systems
- Inductors for maximum power point tracking (MPPT) circuits
- Filter chokes in solar power conditioning units
Operating from our 30,000 sqm manufacturing facility in Dezhou, China, we leverage advanced vertical integration to maintain strict quality control from raw material selection to final packaging. Our wires undergo rigorous testing including:
- Thermal shock cycling (-40°C to 220°C)
- Partial discharge measurements
- Adhesion testing (twist, scrape, and peel tests)
- Chemical resistance validation
With annual exports exceeding $100 million to 12 global markets and certifications including ISO14000 environmental management standards, we guarantee products that meet international safety and performance requirements. Our dedicated engineering team supports custom specifications for diameter tolerances within ±0.001mm and specialized packaging solutions. Partner with Huilong for magnet wires that enhance your solar inverter's reliability while reducing total system costs through extended service life.
FAQ:
Q1: What insulation materials enable 200°C operation?
A: We utilize modified polyester-imide resin systems with thermal stabilizers that maintain dielectric integrity at elevated temperatures.
Q2: Can this wire withstand high-frequency switching in inverters?
A: Yes, our proprietary enamel formulation minimizes skin effect losses at frequencies up to 100kHz.
Q3: What lead times can be expected?
A: Standard diameters ship in 2-3 weeks; custom specifications require 4-5 weeks. Express options available.
Q4: Are RoHS-compliant versions available?
A: Environmentally friendly formulations without restricted substances can be provided upon request.
Q5: How does this wire compare to aluminum alternatives?
A: Copper provides 40% better conductivity, allowing compact designs with lower thermal rise in space-constrained inverters.
Q6: What packaging options exist?
A: Standard wooden spools (ISO dimensions), or customized packaging to prevent deformation during shipping.
Q7: Can you provide samples for testing?
A: Sample spools (100-500g) are available for technical evaluation with minimal lead time.
Q8: What quality documentation accompanies shipments?
A: Each batch includes test certificates for dimensional accuracy, breakdown voltage, and thermal endurance.
