Thin copper wire insulated is a popular choice across a wide range of industries where space, flexibility, and low-voltage performance matter. These small-diameter copper wires—typically 20 AWG and finer—are insulated with high-quality materials to ensure safe, consistent operation in demanding environments.

What Is Thin Insulated Copper Wire?
“Thin” generally refers to smaller-gauge copper wires, often ranging from 20 AWG to 30 AWG or finer, depending on the application. These wires are used in compact electronics, signal transmission, LED lighting systems, audio wiring, robotics, and more. The insulation—often PVC, PE, or Teflon—protects the conductor while maintaining flexibility and strength.
Key Features
✅ High Conductivity: Solid or stranded bare copper core ensures excellent electrical performance
✅ Space-Saving: Slim profile is ideal for confined or miniaturized spaces
✅ Durable Insulation: Withstands bending, vibration, and environmental exposure
✅ Versatile Applications: Compatible with low-voltage DC, signal, and communication systems
