Copper-clad steel ground rod vs. pure copper ground rod, who has the advantage?

17-04-2020

The copper-clad steel ground rod is one of the indispensable grounding devices in order to allow the conductor to fully contact the ground to ensure the smooth discharge of the current of the copper-clad steel ground rod. Through the joint action of the slow-release ground rod and the synergistic electrolytic ion filler, a copper-clad steel ground rod is formed in the inner environment of the shell. The internal and external fusion of this internal environment gradually diffuses to the surroundings, and the chemical treatment of the shell soil is completed together .

 

Although the performance of pure copper ground rods is good, copper-clad steel ground rods are good, but the cost is high and the strength is poor. It is not suitable to penetrate into the ground. In general, the above copper-clad steel ground rods can be used in many occasions. Therefore, it can effectively solve the many setbacks of the copper clad steel ground rod in the grounding technology, and has become a good technical replacement scheme. There is no special requirement for soil. The smaller the soil resistivity, the better the copper-clad steel ground rod.

Because the content of active ions in the soil is one of the factors of the copper-clad steel grounding rod that affects the grounding resistance, many compounds containing active electrolytic ions in the soil are relatively rare, and the simple grounding body will not meet the grounding requirements. The material of the ground rod is generally copper-clad steel. For example, the surface of the steel is plated with copper, which has the high conductivity of copper and the characteristics of steel. Currently, many companies produce such ground rods. The copper-clad steel grounding rod is suitable for general environment and special environment of wet, saline-alkali, acid mud copper-clad steel grounding rod soil and chemical erosion medium. Generally, anti-corrosion treatment is not done.

 

If the conductivity of the soil cannot meet the requirements of the use, the buried depth of the copper-clad steel ground rod can generally be deepened. In the acidic soil environment, the acidic corrosivity is relatively large. After a long time, pure copper will produce a patina, and after a longer time, it will slowly corrode. The impact on the electrical conductivity is to replace it after a long time. Only stainless steel is used for integration. Not so good, after all, it is less rusty and the time of the steel is longer. It is not easy to rust. The conductivity of the steel is not as good as that of copper. The copper clad steel has the best effect. After the copper is corroded, the surface is close to the steel. It can better integrate into the earth. And the price is not expensive.
