Core Product Features & Advantages

• ✓ Lightweight & High Cost Performance
Low-density aluminum conductor greatly reduces the overall weight of coils and end equipment. Compared with enameled copper wire, it effectively cuts raw material and production costs while maintaining qualified electrical conductivity, ideal for mass industrial production.

• ✓ 4-Grade Ultra-wide Heat Resistance (130℃–220℃)
Covers full temperature grades from conventional 130℃/155℃ to high-end 180℃/220℃. Premium composite enamel coating resists thermal aging and high-temperature decomposition, preventing insulation breakdown and coil burnout during long-term continuous operation.

• ✓ Stable Insulation & Low Loss
Uniform, flawless paint film delivers high dielectric strength and ultra-low insulation loss. It effectively avoids electric leakage and short circuits under high-frequency operation, ensuring long-term stable and safe operation of electrical equipment.

• ✓ Precise Dimension & Superb Processability
Strict tolerance control with smooth and round wire surface. Excellent flexibility, bending resistance and anti-cracking performance, perfectly matching high-speed automatic winding machines, no paint peeling or wire deformation during processing.

• ✓ Easy Welding & Firm Adhesion
Class 130 wire supports direct soldering without paint stripping, greatly improving production efficiency. All grades feature strong bonding force between enamel layer and aluminum core, resisting peeling after repeated bending and impact.

• ✓ Anti-Aging & Long Service Life
Special anti-corrosion and anti-aging coating adapts to humid, variable-temperature and complex working environments. Effectively resists oxidation and chemical erosion, extending the service life of finished coils and equipment.

• ✓ Eco-Friendly & Export Compliant
Adopts non-toxic environmental protection raw materials and standardized production processes, fully compliant with international environmental protection regulations. Qualified for global export of electrical and electronic products.
