As a seasoned manufacturer established in 1970, Shandong Huilong Electrical Material Co., Ltd. delivers precision-engineered rectangular enamelled aluminium wire specifically designed for inductor applications. With over 50 years of expertise and a 10,000-30,000 sqm factory, we produce wires that combine superior conductivity with exceptional insulation integrity. Our global reach across North America, Europe, Asia, and other markets, supported by an annual export value exceeding $100 million, ensures you receive industry-trusted components. The 0.5mm x 3mm rectangular profile optimizes space utilization in windings while reducing overall system weight.
Key Technical Specifications: This aluminium wire features high-precision dimensional stability and enamel insulation that withstands thermal stresses. The rectangular cross-section enhances packing density in coils by up to 20% compared to round wires, improving inductor efficiency. Electrical properties include:
- Low AC resistance for reduced energy losses
- Class 155 thermal rating (standard, higher classes customizable)
- Excellent dielectric strength exceeding 5kV/mm
- Flexibility retention across temperature cycles
