Among the many lightning protection grounding materials, why the copper clad steel grounding rod sta

Botou Shengtai copper-clad steel grounding rod is: the pure copper is evenly covered on the low-carbon steel core with special electroforming technology, so that the copper and the steel core are completely molecularly combined (if the combination of the two is not dense, in the case of electricity, the galvanic cell reaction will be generated, and the anode metal iron will be oxidized and turned into iron ion loss, which will accelerate the corrosion of the steel core). It has the characteristics of copper layer thickness (more than millimeter), good adhesion, and no peeling (rollable threads).

Its advantages are high tensile strength (600 Newtons square millimeters tall), strong corrosion resistance (can guarantee a service life of more than 50 years), constant low resistance and good plasticity, both with the same performance as copper and steel characteristics. The process can effectively slow down the speed of oxidation of the grounding rod in the ground, Shengtai grounding rod can be divided into single and combined two, a single one can be a sharp end and one flat, can be a sharp end and a roll on the thread, the two ends of the combination need to be threaded on the roll, the thread is the use of roll thread groove processing thread, to maintain the tight connection between steel and copper, to ensure high strength, with excellent electrical grounding performance.

The problem is somewhat strange.

Among the many lightning protection grounding materials, the grounding rod is only one.

Recently, the use of copper-clad steel grounding rods is only a progressive application of industrial technology, but whether it can be successfully operated commercially depends on more, after all, it depends on the actual effect, and the technical effect of copper-clad steel can outperform hot-dip galvanizing? Isn't there a decade or eight years that can reflect that?

But in terms of environmental protection, it is indeed better than hot-dip galvanized products.

There are no works made of zinc-clad steel and copper-clad steel. The materials used in lightning protection and grounding are hot-dip galvanized steel.

Galvanizing on the surface of steel is a surface protection method, because the potential of zinc and iron is different, when it is subjected to oxidative erosion, zinc is oxidized first, and the oxide of zinc is dense, which can prevent further oxidation at depth, unlike rust that is loose and expands in volume, and continues to rust at depth. But copper is different, copper is unstable and easy to oxidize in the air, placed in moist soil, loose copper oxide, copper hydroxide is extremely undurable.

Copper plating is only used in industry as a transition layer, such as chromic plating.

Copper conducts electricity more easily than zinc, you say.

Copper-clad steel grounding rod is selected with good softness, carbon content in high-quality low-carbon steel, using a special process to evenly cover the surface of high conductivity electrolytic copper to the surface of round steel, the thickness is in, the process can effectively slow down the rate of oxidation of the grounding rod in the ground, the grounding rod can be divided into two kinds: single and combined, single can be a tip and a flat, can be threaded on a roll at one end, the two ends of the combination need to be threaded on the roll, and the thread is processed by the roll thread groove, which maintains a tight connection between the steel and copper. Ensures high strength and excellent electrical grounding properties.

Main rod: The grounding electrode is made of high-quality cold-drawn steel, and the copper is cast with special equipment (the thickness is and the copper content is used to ensure that it has excellent conductivity and mechanical strength, and the product has excellent anti-corrosion performance. Connecting Tube:

The rod can be connected with copper connecting pipe, which has the best anti-corrosion effect. The rod is in close contact with each other, and the driving force acts directly on the ground electrode when the grounding electrode is driven into the ground or the driving drill is used to drill into the ground. It is divided into threaded and non-threaded connections.

The biggest advantage of copper-clad steel flat wire is anti-corrosion, but to be honest, its anti-corrosion effect is still not as good as the effect of hot-dip galvanizing, so it can only play a general role in lightning protection and grounding.

Some people may think that copper has a much better conductivity than steel, but forget about the occasion, for high-voltage and high-current lightning, the difference is not much.

The largest copper-clad steel used in this industry is copper and steel alloy, which is the industry foundation of developed countries.

Connecting pipe: The rod can be connected by copper connecting pipe between the rod, and the copper-clad steel grounding electrode has the best anti-corrosion effect. Club.

The contact with the rod is close, and the driving force directly acts on the connection when the grounding rod is driven into the ground or the driving drill is used to drill into the ground.

Ground sticks. It is divided into threaded and non-threaded connections.

Drive head: Made of high-strength alloy steel, the ion grounding rod can ensure that the driving force is smoothly driven into the ground.

Alloy tip: Guaranteed to be driven into the ground in complex geological conditions.

Main rod: The grounding rod is made of high-quality cold-drawn steel, and the special equipment for exothermic welding is cast copper (the thickness is.

Copper content to ensure that it has excellent conductivity and mechanical strength, resistance reducer for this product.

It has excellent anti-corrosion performance. Copper-clad steel grounding rod This product has been widely used in electric power, petrochemical industry, transportation, civil construction, and large-scale mechanical installation.

The grounding system has the characteristics of long service life, economy and excellent conductivity.

1. Yes, but not greatly, copper and aluminum contact oxygen return to travel is worthy of the first attention;

2. The electric oxidation is obvious, especially the larger the current, the more powerful; The time parameters of lightning protection seem to be negligible;

3, the sedan car is the lightning protection grounding copper rod and the foundation in the steel bar closed shed direct connection process in the modern technology has been almost not adopted, because the ground resistance of the foundation pile and the ring beam has been far better than the simple lightning protection grounding copper rod.

The electrochemical reaction of the lightning protection grounding copper rod with the steel bar in the foundation is conditional

If one of the two is dried on an old site, or if one is completely sealed (impermeable), or if the two are not connected, no electrochemical reaction will occur.

If the two are conductive and wet, an electrochemical reaction can occur that causes the steel bar to corrode at an accelerated pace.

The conditions for the delay reaction of electrochemical jujube are: two different active metals are conductive and connected by conductive liquids to form a loop.

A reaction is definitely going to happen.

There must be an electrochemical reaction between copper and iron, and iron loses electrons and is oxidized
