Explore our precision-engineered core product configurations built to meet stringent international standards for heat resistance, windability, and dielectric performance.
Polyurethane-coated copper cables, widely recognized as UEW (Polyurethane Enameled Wire), form the fundamental infrastructure powering modern electronics, electric mobility, and grid intelligence. By leveraging a high-performance thermosetting polymer topcoat applied over premium high-purity copper, these cables offer a unique balance of thermal resistance and direct solderability without previous mechanical insulation removal.
As the world pivots toward extreme automation and high-density electrification, the global demand for UEW has grown significantly. High-frequency windings in telecommunication devices, micro-relays, and advanced automotive ignition systems require thin-film wire profiles that do not fail under localized thermal stresses. We address this demand by providing high-tolerance, thin-film insulated copper options that improve transmission efficiency while keeping your production workflows smooth.
Compared to traditional polyvinyl formal (PVF) or polyesterimide coatings, polyurethane coatings provide a highly protective insulation jacket with an exceptionally low dissipation factor. This thermal and electrical profile makes it highly suitable for high-frequency signal processing, aerospace sub-systems, and precision medical imaging coils.
Our engineering team designs every wire batch to exceed performance benchmarks outlined by IEC, NEMA, and UL standards. The parameters below illustrate our commitment to reliability.
| Thermal Class / Standard Designation | Base Polymer Layer | Overcoat Compound | Self-Soldering Temp Window | Primary Industrial Application |
|---|---|---|---|---|
| Class 130 (MW 79-C) | Polyurethane | Nylon (optional) | 360°C - 380°C | Relay coils, small motors, solenoid valves |
| Class 155 (MW 80-C) | Polyurethane Modified | Polyamide / Nylon | 370°C - 395°C | Automotive relays, ignition coils, transformer components |
| Class 180 (MW 82-C) | Polyurethane High-Temp | Polyesterimide modifier | 390°C - 420°C | Sensors, power supplies, telecom high-frequency coils |
| Class 200 / 220 (MW 83-C) | Polyesterimide / Polyamide-imide | Polyamide-imide (PAI) | N/A (Requires stripping) | High-voltage power transformers, heavy industrial traction motors |
