The usual grounding construction mainly uses metal conductors, such as galvanized angle steel, galvanized round steel, galvanized steel pipe, copper plated grounding rod, copper mesh, etc. Its disadvantages are that it requires a lot of materials, high cost, complex construction difficulty, short service life, and poor stability. It is difficult to achieve the expected effect when used in high soil resistivity areas. This low resistance grounding module uses less material, has a lower cost, greatly simplifies construction, and has a long service life and good stability. It is particularly suitable for use in high resistivity soil areas, such as wind power generation, photovoltaic power stations, and other sand or rock formations. It can be used to solve the problems in grounding engineering construction. High purity graphite grounding body products are pollution-free, non-toxic, corrosion-resistant, and very convenient to use. Below, the editor in charge of graphite grounding will introduce:
Characteristics and technical advantages of copper plated grounding rod:
1. Unique manufacturing process: using cold rolling and hot drawing production technology to achieve metallurgical fusion between copper and steel. It can be pulled freely like pulling a single metal, without detachment, warping, or cracking.
2. Superior corrosion resistance: The composite interface adopts high-temperature welding, with no residue and no corrosion phenomenon on the joint surface; The surface copper layer is thick (with an average thickness greater than 0.3mm), has strong corrosion resistance, and has a long service life (greater than 30 years), reducing the intensity of maintenance labor.
3. Better electrical performance: The excellent conductivity of the surface copper material makes its own resistance value much lower than conventional materials.
4. Widely safe and reliable: This product is suitable for grounding construction under different soil moisture, temperature, pH value, and resistivity changes.
5. Safe and reliable connection: using dedicated connecting pipes or hot melt welding, the joints are firm and stable.
6. Easy and fast installation: With complete accessories and convenient installation, it can effectively improve construction speed.
7. Improve grounding depth: With a special connection transmission method, it can penetrate up to 35 meters underground to meet the low resistance requirements of special occasions.
8. Low construction cost: Compared to the traditional construction method of using pure copper grounding rods and grounding strips, the cost has been significantly reduced.
Main technical parameters of copper plated grounding rod:
1. Copper layer thickness ≥ 0.3mm
2. Tensile strength ≥ 600N/mm
3. Flatness error ≤ 0.5mm/m
4. Copper layer plasticity: When the grounding rod and grounding round wire are bent at 30 degrees, there are no cracks on the inner and outer edges of the bend.
The above is the introduction of graphite grounding by the editor, hoping to help those in need.
