Copper-clad steel grounding rods are also known as copper-clad steel grounding electrodes, copper-clad steel grounding rods, copper-clad steel grounding electrodes, unthreaded copper-plated steel needles, etc., using four-dimensional continuous electroplating, continuous casting or coating and other production processes , produced by covering electrolytic copper to a specific high-strength low-carbon steel core. According to different processing techniques, there are also various titles such as continuous casting copper-clad steel grounding electrodes, continuous casting copper-clad steel grounding rods, copper-clad steel rods, and copper-clad grounding electrodes.
Due to the early processing of copper steel composite grounding material process for cold draw coating, so obtained the name "copper clad steel", although the current cold draw coating process has long been outdated, more current, such as continuous casting, four-dimensional continuous plating and other processes have become the main production process for processing such products, but the name "copper clad steel" has been used until now. Although most copper-steel composite products are no longer "packaged" processes.
1. Copper clad layer thickness ≥ 0.254mm (in line with UL 467 "Safety Standards for Grounding and Bonding Equipment")
2. Tensile strength 60000n/cm2 Flatness error ≤ 1mm/m
3. Plasticity of the copper layer: when the ground rod (wire) is bent at 30 degrees, there will be no cracks on the inner and outer edges of the corner
4. Bonding degree of copper layer: After the adhesion test, except for the peeling copper layer at the occlusion of the vise jaws, the rest of the copper and steel bonded well without peeling.
5. The grounding rod can be connected according to the required length, and the grounding rod can go deep underground for 30m without being affected by any climatic conditions (such as drought and frost) that may increase soil resistivity and grounding resistance.
The advantages of the product are as follows:
1. 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 technology: It is produced with advanced technology, and the copper layer will not fall off, warp or crack when bent 180 degrees.
3. Excellent anti-corrosion performance: the thickness of the copper plating layer is greater than 0.254mm, with strong corrosion resistance and long service life (more than 50 years).
4. Wide practicability: It is suitable for grounding construction under the conditions of temperature, moderate temperature, soil with different pH and resistivity changes.
5. The connection is safe and reliable: using special connecting pipes or exothermic welding, the joints are firm and stable.
6. Convenient and fast installation: complete accessories and convenient installation can effectively improve construction efficiency.
7. Improve the grounding depth: the special connection and transmission mode can go 35 meters underground to meet the requirements of low resistance value in special occasions.
8. Low construction cost: Compared with the traditional construction method of using pure copper grounding rods and grounding strips, the cost is greatly reduced.
