Unique Manufacturing Process: Produced using a cold-rolling and hot-drawing process that achieves a metallurgical bond between the copper and steel. The rods can be drawn like a single metal without separation, peeling, or cracking. They pass adhesion and 300°C thermal shock tests without the copper layer peeling off, ensuring a secure bond. The product features a smooth, burr-free finish and high straightness (deviation ≤1mm/m).
Corrosion Resistance: The composite interface is formed via high-temperature bonding, leaving no residue and minimizing the risk of corrosion at the junction. The surface copper layer is thick and uniform, typically ranging from 0.25mm to 0.5mm. Leveraging the skin effect of electric current and the inherent corrosion resistance of copper, the product offers excellent electrical conductivity and durability. It boasts a long service life-theoretically exceeding 40 years, with some products reaching up to 50 years when used with specific backfill materials or installation techniques.
Electrical Performance: The surface layer of pure copper offers excellent conductivity, resulting in lower electrical resistance compared to conventional materials.
Applicability: Suitable for grounding installations across a wide range of soil conditions, including varying moisture levels, temperatures, pH values, and resistivity.
Connection Methods: Connections are made using specialized couplers or exothermic welding, ensuring strong, stable joints.
Installation: A full range of accessories is available, making installation convenient; couplers and other fittings are manufactured from high-quality materials.
Grounding Depth: Thanks to a unique connection mechanism, the rods can be driven up to 35 meters underground to meet low-resistance requirements in specialized applications.
Construction Cost: Compared to traditional methods using solid copper rods or grounding strips, copper-clad steel grounding rods offer lower construction costs.
