Advantages of composite insulation coating for aluminum enameled wire
- Stronger heat performance: Composite insulation enables wires to excel in high temperatures, ideal for applications where traditional enamel wires may falter.
- Higher temperature resistance rating: Wires often have high-temperature ratings, like 220°C or higher, ensuring continuous operation in extreme heat without sacrificing performance, ideal for demanding industrial settings.
- Stronger chemical corrosion resistance: The polyamide-imide in the insulation offers excellent chemical, solvent, and oil resistance, ensuring reliable wire performance in harsh chemical environments.
- Higher abrasion resistance: Composite insulation provides superior abrasion resistance compared to traditional enamel, ensuring excellent wire performance in mechanically demanding applications.
