The image displays a bundle of copper earth rods. These rods are used in electrical grounding systems to provide a safe, low-resistance path for fault currents to dissipate into the earth.
Specifications
- Material: Typically solid copper or a steel core with an electrolytic copper bonding/coating (copper-bonded steel). The copper coating thickness can vary (e.g., 50µm, 254µm).
- Length: Common lengths include 4 feet (1.22 meters), 6 feet, or 3,000 mm (3 meters).
- Diameter: Standard diameters often range from 1/2 inch (12.7 mm) to 5/8 inch (15.9 mm) or 20 mm.
- Corrosion Resistance: Solid copper rods offer extremely high corrosion resistance, while copper-bonded rods also resist corrosion well, allowing for a long service life in most soils.
- Features: Rods may have threaded ends for connecting to grounding clamps or for jointing multiple rods for deeper driving.
- Standards: Products are typically compliant with relevant electrical safety standards and regulations (e.g., UL, IEC).
