4 Gauge Bare Copper Wire

4 gauge bare copper wire is a kind of wire, which is composed of multiple conductors twisted into a bare copper wire with a nominal cross-sectional area of ​​20.150mm2 and a minimum cross-sectional area of ​​20.730mm2 with a diameter of approximately 0.204 inches or 5.189 mm.

1. Large diameter: 4 gauge bare copper wire has a large diameter, which is suitable for applications that need to carry large currents.

2. Excellent physical properties: The wire has good flexibility and electrical conductivity, and is easy to handle and process.

3. Wear resistance and corrosion resistance: There is no protective layer on the surface of the bare copper wire, but the copper metal itself has good oxidation resistance and corrosion resistance, so it has wear resistance and corrosion resistance.

4. Excellent electrical conductivity: The pure copper material with bare copper wire has excellent electrical conductivity.

1. As a grounding conductor in electrical systems and circuits.

2. As the main conductor in the power transmission and distribution system.

3. As a power supply line for high-power electrical appliances and motors.
