Copper-Clad Steel Grounding Electrode / Grounding Rod
I.Product Introduction
The copper-clad steel grounding rod is manufactured using unique production processes and advanced technology introduced from France. The product combines the low electrical resistance, strong corrosion resistance, and excellent electrical connectivity of copper with the high strength and construction convenience of steel, making it the best choice to replace traditional metal grounding materials. Utilizing advanced French electroforming technology, the copper layer is integrally bonded, providing excellent plasticity. It can be threaded, bent, and is easy to transport and install. It can be widely used in grounding systems for power transmission and transformation, power plants, communication base stations, buildings, and antenna grounding devices. Together with air terminals (lightning rods, lightning wires) and down conductors, it forms a comprehensive lightning protection and grounding system.
II.Product Features
◆ Advanced French Manufacturing Process
Produced using top-tier French new copper electroforming technology, it will not delaminate or crack even when bent 180 degrees.
◆ Low Cost, Wide Application Range
Compared with traditional pure copper grounding rods, the cost is reduced by 70%. The special multi-segment connection method allows it to penetrate up to 35 meters underground, meeting construction requirements in special environments. It is suitable for any engineering project and has a very wide range of applications. When used in conjunction with flexible grounding technology, it can significantly reduce the length of deep wells and save construction costs.
◆ Strong Anti-corrosion Properties
The surface oxygen-free copper layer is thick (up to 0.256～0.5), providing strong corrosion resistance. It is suitable for soil environments with different PH values, resistivity, humidity, and temperatures, with a service life exceeding 30 years.
◆ Easy Construction
Connected by WM exothermic welding or clamp fixation, it is fast and simple, with firm joints and good stability.
◆ Significant Resistance Reduction Effect
The surface oxygen-free copper material has high electrical conductivity, and its resistance reduction effect is significantly better than that of ordinary metal materials.
III.Product Specifications
Example: HD-Φ14.2 indicates that the diameter of the grounding rod is 14.2mm.
It indicates that both ends are threaded. If there is no specific annotation, it defaults to one pointed end and one flat end.
Note:All the models listed above feature one pointed end and one flat end; if you require both ends to be threaded, please specify this before placing your order.
IV.Technical Testing
1.Tensile Strength: ≥ 600 N/mm².
2.Copper Layer Bonding: After the adhesion test, the copper-steel bond on the rod body is good with no peeling observed. A slight flaking of the copper layer at the jaws of the pliers is considered normal mechanical wear from clamping. The grounding rods can be lengthened to the required depth using coupling joints to penetrate up to 35 meters underground, thereby reducing the impact of climatic conditions (such as frost and drought) on soil resistivity and grounding resistance.
