Copper-clad steel grounding rods are also called copper-clad steel grounding electrodes, copper-clad steel grounding rods, copper-clad steel grounding electrodes, threadless copper-plated steel needles and other different names. Our company uses four-dimensional continuous electroplating, continuous casting or cladding and other production processes to cover electrolytic copper on a specific high-strength low-carbon steel core. According to different processing techniques, there are also various different titles such as continuous casting copper-clad steel grounding electrodes, continuous casting copper-clad steel grounding rods, copper-clad steel rods, and copper-plated grounding electrodes. Since the earliest processing technology for copper-steel composite grounding materials was cold-drawn cladding, it was named "copper-clad steel". Although the cold-drawn cladding process has long been outdated, more processes such as continuous casting and four-dimensional continuous electroplating have become the main production processes for processing such products, but the name "copper-clad steel" has been used to this day, although most copper-steel composite products are no longer "clad" processes. Our company's products have a sufficiently dense and uniform copper layer thickness (greater than 0.254mm) and copper layer purity (99.9% and above). Due to the existence of the skin effect (especially when high-frequency current flows, such as lightning current, the skin effect is more obvious), its conductivity and corrosion resistance (which determines the life of the grounding grid, which is very important) are close to pure copper, but the price is lower than that of pure copper materials. At the same time, due to the internal high-strength steel core, it has sufficient mechanical strength (tensile strength greater than or equal to 60000n/mm2), and can be installed to a considerable depth using an impact hammer. It has the advantages of both copper and steel materials and is the most suitable composite grounding material for grounding purposes. 1. Copper coating thickness ≥ 0.254mm (in compliance with UL 467 "Safety Standard for Grounding and Bonding Equipment")
2. Tensile strength 60000n/cm2 Straightness error ≤ 1mm/m 3. Plasticity of copper layer: When the grounding rod (wire) is bent 30 degrees, there is no crack on the inner and outer edges of the corners 4. Copper layer bonding: After the adhesion test, except for the peeling copper layer at the bite of the jaws of the tiger's mouth, the rest of the copper and steel are well bonded and no peeling occurs. 5. The grounding rod can be connected to the required length, and the grounding rod can be 30m underground without being affected by any climatic conditions (such as drought and frost) that may increase the soil resistivity and grounding resistance. 3. Product advantages 1. Excellent conductivity: The current skin effect makes the electroplated copper grounding rod have the same conductivity as the copper rod of the same specification; 2. Advanced manufacturing process: It is produced with the most advanced technology, and the copper layer will not fall off, peel or crack when bent 180 degrees; 3. Excellent corrosion resistance: The thickness of the copper plating layer is greater than 0.254mm, with strong corrosion resistance and long service life (greater than 50 years); 4. Wide practicability: It is suitable for grounding construction under conditions of temperature, humidity, soil with different pH and resistivity changes; 5. Safe and reliable connection: Use special connecting pipe or exothermic welding, the joint is firm and stable; 6. Convenient and fast installation: Complete accessories and convenient installation can effectively improve construction efficiency; 7. Increase grounding depth: The special connection transmission method can go 35 meters underground to meet the low resistance requirements of special occasions; Low construction cost: Compared with the traditional construction method of using pure copper grounding rods and grounding strips, the cost is greatly reduced. 4. List of copper-clad steel grounding rod models Jiahe copper-clad steel grounding rods are divided into two types: combined type and single-root type. The combined grounding rod consists of a driving head, a grounding rod, a connector and a ground-breaking tip, and is divided into two types: imperial thread and metric thread. The single-root type has a flat head on one end and a pointed head on the other.
