The working principle and advantages of copper clad steel ground rod

Copper clad steel ground rod is widely used in the field of lightning protection grounding, loved by the majority of customers, set many advantages in the copper clad steel ground rod in the end what are the advantages of the next we will discuss together.

Copper clad steel ground rod process

Copper clad steel ground rod using cold rolling hot drawing process production, to overcome the electroplating method and casing cladding method of poor bonding and other defects, this process to ensure that the copper layer and the permanent molecular link between the steel core, with copper layer thick, low resistance, corrosion resistance, high strength, easy installation, electrical connection performance and other advantages, can effectively use the deep low soil resistivity Reduce the earth resistance, can ensure that the product life in more than 40 years. It is widely used in transmission and communication lines, power stations, buildings and antennas in the grounding device, can also be used for computers and other electronic equipment grounding system, and can be used with lightning catcher (lightning rod, lightning wire) and lead wire to form a lightning protection grounding device.

As copper clad steel ground rod has good electrical conductivity, high mechanical strength, especially the outer clad copper layer has good corrosion resistance, so currently has been widely used in grounding devices. Now the relevant standards in our country are grounding conductor can be used copper clad steel ground rod. copper clad steel ground rod alternative steel or galvanized angle for grounding conductor, has been increasingly accepted by the design institute and engineering construction units, use, attention and popularization.

The working principle of copper clad steel ground rod

The working principle of copper clad steel ground rod. Regardless of the external installation of lightning rod or room installed lightning arrester its ultimate purpose is to invade the lightning energy or internal surge (overvoltage) to guide the discharge into the ground, in order to avoid lightning damage, so the final discharge into the ground is the key to the entire lightning protection project, grounding is to ensure the safe and rapid discharge of current into the earth an important link.

Grounding rod is to make full contact with the conductor and the earth to ensure the smooth discharge of current indispensable grounding equipment. The material of the ground rod is generally copper clad steel, such as steel surface copper plating, that is, the high electrical conductivity of copper and also have the characteristics of steel, there are many companies produce this ground rod. copper clad steel ground rod is suitable for general environment and moisture, saline, acidic soil and produce chemical corrosion media special environment, generally do not do anti-corrosion treatment. No special requirements for the soil, the smaller the soil resistivity the better. If the soil conductivity can not meet the use requirements, generally can deepen the burial depth.

As the content of active ions in the soil is one of the factors affecting the grounding resistance, many soils contain active electrolytic ions in the compound is relatively rare, simple grounding body will not meet the grounding requirements. After experimental comparison, reversible slow-release filler is added to the earthing rod. This filler has the characteristics of being water absorbing, water releasing and reversible. This reversible reaction effectively ensures the effective temperature of the environment within the shell layer and the stability of the earthing resistance. The filler has no toxic side effects and achieves better results in both ion generation and the prevention of corrosion of copper alloys in the long-term cooperative action with metal electrodes. The ions generated in this way absorb the earth's moisture and can then be effectively released into the surrounding soil through dampness, making the ground rod an ion-generating device and thus improving the surrounding soil to meet earthing requirements.

Copper clad steel ground rod features and technical advantages

●unique manufacturing process: copper clad steel ground rod using cold-rolled hot-drawn production process, to achieve metallurgical fusion between copper and steel. This ensures a perfect combination of copper and steel layers, and can be drawn at will like a single metal, without disconnecting, warping or cracking.

●corrosion prevention superior: copper clad steel ground rod composite interface using high-temperature fusion, the surface copper layer ≥ 0.254mm, no residue, combined with the surface will not appear corrosion; surface copper layer thicker (average thickness greater than 0.4mm ) corrosion resistance, long service life (more than 40 years), reduce the maintenance labour intensity.

●the construction cost is low: copper clad steel ground rod compared to the traditional use of pure copper ground rod, grounding strap construction method, the cost has dropped significantly. (And has the strength, pure copper ground rod can not reach)

●the use of a wide range: copper clad steel ground rod suitable for different soil humidity, temperature, PH value and resistivity changes in the conditions of grounding construction.

●safe and reliable connection: copper clad steel ground rod using special connection tube or using hot welding, the joint is firm, good stability.

●Construction is convenient and quick: copper clad steel ground rod has complete accessories and is easy to install, which can effectively improve the construction speed.

●Improve the grounding depth: copper clad steel ground rod special connection drive way, can be deep underground more than 35 meters, to meet the special occasion low resistance value requirements.

●better electrical performance: copper clad steel ground rod surface copper material excellent conductive characteristics, so that its own resistance value is much lower than conventional materials.
