Rectangular Enameled Copper Wire – Class 220 Polyamide-Imide Insulation, High Copper Fill Factor for EV & High-Efficiency Coils

AIW-220 is a premium rectangular enameled copper wire featuring polyamide-imide (PAI) insulation – Class 220, specifically engineered for high-density windings where space efficiency and thermal performance are critical.

Compared to traditional round wires, the rectangular cross-section maximizes copper fill within a given slot or window – achieving 20-30% higher copper density – significantly reducing I²R losses and improving motor efficiency. The polyamide-imide insulation offers excellent thermal stability, chemical resistance, and mechanical strength for demanding applications.

With a thermal class of 220°C (Class N), heat shock resistance up to 240°C, and a cut-through temperature exceeding 320°C, AIW-220 delivers exceptional performance in electric vehicle traction motors, dry-type transformers, and high-frequency inductors.

Key Features & Benefits

📦 Higher Copper Fill Factor
20-30% more copper in the same winding area compared to round wire – lower I²R losses and improved motor efficiency.
🔥 Class 220 Polyamide-Imide
Excellent thermal stability with cut-through temperature ≥320°C, ideal for harsh operating conditions and high-voltage applications.
🛡️ Multiple Film Grades
Available in Grade 1 (Single Build), Grade 2 (Heavy Build), and Grade 3 (Triple Build) for flexible dielectric strength selection.
🔧 Precision Rectangular Profile
Excellent shape retention and winding stability for edge-wound coils and automated forming processes.
🔌 Superior Electrical Performance
High breakdown voltage and stable insulation resistance across a wide temperature range (-40°C to 220°C).
✅ Global Standards Compliance
Meets GB/T 6109.20-2008, IEC 60317-13, and NEMA MW 35-C standards.
