Copper-clad steel grounding rods have obvious effects. Copper-clad steel grounding rods are sold directly from manufacturers in large quantities
Copper-clad steel grounding rods
are made of high-quality low-carbon steel as the base core, covered with a copper layer on the surface, and are carefully processed and manufactured The new composite material is a metal composite material that combines the characteristics of copper and steel. The copper-clad steel grounding rods currently on the market basically use three processes: electroplating, continuous casting, and electroforming. The surface of the steel wire is covered with a copper layer of standard thickness through physical, chemical and other methods, making Jitai The lightning-protected copper-clad steel ground rod has the high strength of steel and the low resistance of copper. Jitai Lightning Protection Cangzhou Branch specializes in providing a variety of copper-clad steel grounding materials with different processes. The copper-clad steel grounding rods produced have bright appearance, precise tensile strength, and good ductility. The size and thickness of the coating can be customized according to the different needs of customers. Made in China, the products fully comply with environmental protection requirements. Copper-clad steel grounding rod
has better electrical performance, and its excellent conductive characteristics make the copper-clad steel grounding rod
resistance much lower than conventional material copper-clad steel grounding rod
easy and fast to install. It can effectively increase the construction speed. Copper-clad steel ground rod
The grounding depth is greatly improved, which can meet the low resistance requirements of various special occasions. The unique manufacturing process realizes the perfect combination between copper and steel. Copper-clad steel ground rod
It has excellent plasticity and can be pulled out like a single metal without any phenomena such as detachment, warping, or breakage. The construction cost is low. Compared with the traditional construction method of using pure copper grounding rods and grounding strips, the cost is significantly reduced. Copper-clad steel Grounding rods
Excellent anti-corrosion properties, strong corrosion resistance, long average service life (greater than annual reduction in labor intensity such as maintenance.
The corrosion of copper-clad steel grounding rods
mainly include surface corrosion and pitting There are two forms of corrosion. Surface corrosion means that the contact surface is uniformly corroded. This kind of corrosion is related to the material of the copper-clad steel grounding rod and the soil corrosion performance. The speed is relatively stable. Point corrosion mainly exists in the joints. In areas that are extremely prone to electrochemical corrosion, the rate of pitting corrosion is
to
times that of the uniform corrosion rate, which is the main form of corrosion that threatens the safety of the grounding grid.

The anti-corrosion ability of the copper-clad steel grounding rod is very poor, and the protection mainly relies on the outer layer of galvanizing. If the welding points and other places where the coating is damaged are not adequately protected during the construction process, it is easy to form spots. Corrosion. The steel grounding grid installed in the substation usually needs to be modified and replaced after ten years. It rarely works stably for fifteen years. Even if the grounding electrode cross-section is greatly increased, it is useless because of the speed of pitting corrosion. If it corrodes too quickly, it will easily corrode and break the horizontal ground network.

The corrosion speed in soil is about that of steel

, the product after the copper material is corroded is basic copper carbonate, which will be tightly adsorbed on the surface of the copper material, blocking the further progress of corrosion, and can also protect the copper material from pitting corrosion. Plating When reasonable, the corrosion resistance of copper-plated steel is equivalent to that of copper. The grounding grid formed by using Jitai lightning protection copper-clad steel grounding rods can operate stably for up to
years.
Copper The effect of using steel-clad ground rods is obvious, and copper-clad steel ground rod manufacturers have a large number of direct sales in stock
The use of copper-clad steel ground rods is effective. Copper-clad steel ground rod manufacturers sell a large number of spot products directly.
