FAQ

1. What is 20 SWG Polyester Enameled Copper Winding Wire?

 20 SWG Polyester Enameled Copper Winding Wire is a high-quality copper wire coated with a thin layer of polyester enamel insulation. It is commonly used for winding coils, transformers, inductors, electromagnets, and motor windings while maintaining electrical isolation between turns.

2. What does "20 SWG" mean in this winding wire?

 SWG stands for Standard Wire Gauge. A 20 SWG wire has an approximate conductor diameter of 0.91 mm, providing a good balance between current-carrying capacity, flexibility, and ease of winding for various electrical and electronics projects.

3. Why is the wire coated with polyester enamel?

 The polyester enamel coating acts as an insulating layer that prevents short circuits between adjacent wire turns. This allows coils and transformers to be wound compactly without requiring additional insulation between each layer.

4. What are the common applications of 20 SWG enameled copper winding wire?

 This wire is widely used in:

  • Transformer winding
  • Motor winding and repair
  • Electromagnets
  • Inductors and chokes
  • Relay coils
  • DIY electronics and educational projects
  • Wireless power transfer experiments

5. How do I make electrical connections using enameled copper wire?

 Before soldering or connecting the wire, the enamel coating must be removed from the wire ends by scraping, sanding, or burning it off carefully. Once the copper surface is exposed, it can be soldered or connected like standard copper wire.
