What Is 200-Class Enameled Copper Wire?
200-class enameled copper wire is a dual-coat winding wire rated for a thermal class of 200 °C. It pairs a high-purity copper conductor with a polyester or polyester-imide basecoat and a polyamide-imide topcoat, giving heat, abrasion and refrigerant resistance for motor and compressor windings.
Why two coats
The basecoat carries the thermal and chemical load. The polyamide-imide topcoat takes the abrasion and winding stress, and adds lubricity. Splitting the two jobs is what lets the film hold up in high-speed winding and in sealed refrigerant systems where a single-coat film would be marginal — and it keeps cost lower than building the whole film from the more expensive resin.
What you get
- Excellent refrigerant resistance for hermetic compressor systems
- Stable heat resistance through continuous thermal cycling
- Tough, uniform film with high scrape resistance — fewer wire breaks at high winding speeds
- Lubricated surface tuned for high-speed automatic winders
- Every production lot tested in CNAS-accredited laboratories for batch-to-batch consistency

Spool types and pallet configuration — copper wire
Single spools for samples or small orders are packed individually in a wooden case or paper drum. Volume shipments use fumigation-free wooden pallets, with cartons or fibreboard collars protecting the spools and stretch film securing the load.
| Spool type | Average wire weight (kg) | Pallet size (mm) | Spools per pallet | Max layers |
|---|---|---|---|---|
| PT-25 | 25 | 1030 × 1030 | 16 | 2 |
| PT-45 | 40 | 1100 × 1100 | 16 | 1 |
