Engineered to deliver exceptional thermal stability, dielectrical strength, and structural resilience under continuous load conditions.
The demand for enameled wire products continues to surge, driven by electrification, renewable energy integration, and advancements in automotive architectures. Enameled wire—also known as magnet wire—serves as the core conductor for electromagnetic coils.
As manufacturers worldwide grapple with fluctuating copper raw material prices, Copper-Clad Aluminum (CCA) Enameled Wires have emerged as a premier cost-reduction alternative, balancing conductivity and weight. Concurrently, high-efficiency transformers rely increasingly on advanced Continuously Transposed Conductors (CTC) to minimize eddy-current losses.
Understanding insulating polymer films (PEW, UEW, EIW, AIW) and thermal categories to maximize efficiency in tough operating environments.
Standard high-durability coating offering excellent mechanical strength and resistance to common solvents. Widely applied in standard electronic components and small power motors.
Features unique direct-solder properties without prior insulation stripping. Perfect for high-frequency telecommunication coils and precise relays.
High-temperature performers certified for 180°C to 220°C classes. Offers chemical resistances, overload tolerance, and mechanical toughness.
| Insulation Classification | Base Resin Chemistry | Thermal Index (°C) | Primary Advantages | Target Applications |
|---|---|---|---|---|
| Class 130 (B) | Polyurethane (UEW) / Polyester | 130°C | Fast self-soldering, high flexibility | Small transformers, instrument coils |
| Class 180 (H) | Modified Polyurethane / Polyesterimide | 180°C | Excellent dielectric strength, heat resistance | Industrial automation sensors, power tools |
| Class 200 (K) | Polyesterimide (EIW) | 200°C | High cut-through resistance, solvent immune | Hermetic compressor motors, dry-type transformers |
| Class 220 (N) | Polyamide-imide (AIW) / Polyimide | 220°C | Maximum thermal overload limits, corona resistance | 800V EV traction motors, high-voltage wind generators |
