The copper-clad steel grounding rod is one of the most widely used grounding solutions in modern grounding systems. It combines the strength of steel with the conductivity of copper, making it an ideal choice for various applications. This product offers excellent electrical performance, ease of installation, and cost-effectiveness, which makes it a popular option in both residential and industrial projects.
During the manufacturing process, high-quality low-carbon steel (with carbon content between 0.10% and 0.30%) is used as the core material. A thick layer of high-conductivity electrolytic copper is then uniformly applied to the surface using a special plating technique. The copper coating typically ranges from 0.25mm to 0.5mm in thickness, significantly enhancing the corrosion resistance and prolonging the service life of the grounding rod. Additionally, the threading is done through a rolling process that ensures a strong bond between the copper and steel layers, maintaining structural integrity and excellent conductivity.
The unique cold-rolling and hot-drawing manufacturing method allows the copper and steel to form a metallurgical bond, eliminating issues like cracking or warping. This results in a durable, flexible, and reliable grounding solution. The copper layer also acts as a protective barrier, slowing down oxidation and ensuring long-term performance underground.
This grounding rod is highly resistant to corrosion, thanks to its thick copper plating (typically over 0.4mm). The high-temperature welding process ensures no gaps or residues on the interface, preventing any potential for corrosion. As a result, the grounding rod can last more than 30 years, reducing maintenance efforts and costs.
In terms of electrical performance, the copper-clad steel grounding rod outperforms traditional materials. Its low resistance and high conductivity make it suitable for use in a wide range of soil conditions, including varying levels of moisture, temperature, pH, and resistivity. This versatility ensures safe and reliable grounding in different environments.
The connection method is also robust, using either specialized connecting pipes or hot-melt welding techniques. These methods ensure a stable and secure joint, improving overall system reliability. Installation is straightforward and efficient, with complete accessories provided to speed up the construction process.
Another advantage is the ability to install the grounding rod at greater depths—up to 35 meters. This deep installation helps achieve lower resistance values, meeting the requirements of critical applications such as power stations and telecommunications infrastructure.
Compared to pure copper grounding rods and grounding belts, copper-clad steel rods offer significant cost savings without compromising performance. This makes them an economical and effective choice for large-scale grounding projects.
