Common grounding construction is mostly based on metal conductors, such as galvanized angle steel, galvanized round steel, galvanized steel pipes, copper-plated grounding rods, copper mesh, etc. The disadvantages are that it uses a lot of materials, costs a lot, is difficult to construct, and has a short lifespan. , poor stability, it is difficult to achieve the expected results when used in areas with high soil resistivity. This kind of low-resistance grounding module uses less materials, costs less, greatly simplifies construction, has a long life and has good stability. It is especially suitable for use in high-resistivity soil areas, such as wind power generation, photovoltaic power stations, etc. for connecting sand, gravel or rock. The ground layer can be used to solve problems in the construction of grounding projects. High-purity graphite grounding products are pollution-free, non-toxic, corrosion-resistant and very convenient to use.
Features and technical advantages of Copper Bonded Earth Rod (Un-Thread):
1. Unique manufacturing process: using cold rolling and hot drawing production process to achieve metallurgical welding between copper and steel. It can be pulled out like a single metal without any detachment, peeling or cracking.
2. Excellent anti-corrosion: the composite interface adopts high-temperature welding, no residue, and no corrosion will occur on the joint surface; the surface copper layer is thick (average thickness is greater than 0.3mm), has strong corrosion resistance, and has a long service life (more than 30 years) , Reduce the labor intensity of maintenance.
3. Better electrical performance: The excellent conductive properties of the surface copper material make its resistance value much lower than that of conventional materials.
4. Wide range of safety and reliability: This product is suitable for grounding construction under different soil moisture, temperature, PH value and resistivity changes.
5. The connection is safe and reliable: use special connecting pipes or hot-melt welding to ensure strong joints and good stability.
6. Easy and fast installation: Complete accessories and convenient installation can effectively increase the construction speed.
7. Improve the grounding depth: The special connection transmission method can penetrate 35 meters underground to meet the low resistance requirements of special occasions.
8. Low construction cost: Compared with the traditional construction method of using pure copper grounding rods and grounding strips, the cost has dropped significantly.
Main technical parameters of copper-plated ground rod:
1. Copper layer thickness ≥0.3mm
2. Tensile strength ≥600N/mm
3. Straightness error ≤0.5mm/m
4. Plasticity of the copper layer: When the grounding rod and grounding round wire are bent at 30 degrees, there will be no cracks on the inner and outer edges of the corners.
