The difference between pure copper grounding wire and Copper clad steel grounding wire

The main differences between pure copper grounding wire and copper-clad steel grounding wire are material composition, conductivity, corrosion resistance and applicable scenarios. ‌

1. Material composition
‌Pure copper grounding wire‌: Made of pure copper, with a copper content of up to 99.95%, it has good conductivity and corrosion resistance‌
‌Copper-clad steel grounding wire‌: It is composed of a high-strength steel core and a copper layer, and the thickness of the copper layer is generally above 0.25mm‌

2.Conductive performance
‌Pure copper grounding wire‌: Excellent conductivity, low resistivity, able to quickly conduct current and maintain a low grounding resistance value‌
‌Copper-clad steel grounding wire‌: High resistivity, relatively poor conductivity, but in some cases, its corrosion resistance is relatively good Strong ‌
 

3. Corrosion resistance ‌

Pure copper grounding wire‌: Due to the high copper content, it has strong corrosion resistance, but requires better protection under complex grounding conditions ‌
Copper clad steel grounding wire‌: Weak corrosion resistance, prone to inner layer corrosion ‌
 

4. Applicable scenarios ‌

Pure copper grounding wire‌: Suitable for occasions with high safety requirements, such as large facilities such as power stations, to ensure the safety of the facilities ‌
Copper clad steel grounding wire‌: Suitable for small facilities, such as household electricity, small factories, etc., because of its low cost and guaranteed use effect ‌
