采用铜覆钢圆线 圆钢，由于铜的金属活泼性差，一般不会与酸、碱、盐发生反应。根据集肤效应，当表面铜层大于 0.25mm 时，钢芯载流很小，利用钢的强度将铜导体送到地下，表面铜层不会发生腐蚀现象，因而圆线 圆钢电阻不会随着时间的推移发生变化，可实现免维护，寿命一般可达 50 年。对比采用镀锌角钢(圆钢)做接地体，虽然减慢了钢的腐蚀，但因锌比钢活泼，锌的腐蚀速度比钢更快，由于镀锌层与土壤接角，而它却在不断的腐蚀不断的变化，稳定性差，使用寿命较短(一般均在 5年以下)每年还需检测电阻阻值，工作量大。

Advantages of using copper-clad steel series as grounding materials
The use of copper-clad steel round wire round steel, due to the poor metal reactivity of copper, generally does not react with acids, alkalis, salts. According to the skin effect, when the surface copper layer is larger than 0.25mm, the current carrying capacity of the steel core is very small, and the copper conductor is sent to the underground by the strength of the steel, and the surface copper layer does not corrode, so the round wire resistance does not follow Changes in time can be achieved, maintenance-free, and life expectancy of up to 50 years. Compared with galvanized angle steel (round steel) as the grounding body, although the corrosion of the steel is slowed down, because zinc is more active than steel, the corrosion rate of zinc is faster than that of steel. Because the galvanized layer is in contact with the soil, it is Continuous corrosion changes, poor stability, short service life (generally less than 5 years), the resistance value needs to be detected every year, and the workload is large.
The copper-clad steel grounding round wire is a new type of grounding body made by our company by electroplating and continuous casting. It adopts advanced technology to cover the surface of special steel core with 99.9% purity copper. The conductive performance is the same as that of the same diameter copper rod. However, the cost is much lower than that of pure copper. The anti-corrosion performance is far better than that of galvanized steel. It has many advantages such as good electrical conductivity, low resistance, excellent corrosion resistance, convenient transportation, convenient construction and high construction efficiency. It is an alternative to round steel, angle steel and galvanized. A good choice for traditional grounding materials such as flat steel.
Copper-plated round wire round steel production process
Copper-plated round wire The four-dimensional plating method of round steel adopts the domestic advanced nano alkaline pre-plating copper technology. The principle is to construct aerodynamic field environment, finely control the density and deposition rate of nano-sized clusters of complexes and Cu2+ in the plating solution, and construct a new nano-scale particle deposition model between copper and steel. metal deposition forms a nano-sized alkaline copper particle crystal coating structure, and the nano-scale crystal plating layer has good compactness and high activation surface, which greatly enhances the affinity between the plating layers, so that the bonding force reaches a better standard. The finished product has excellent mechanical strength, ductility and corrosion resistance.
Copper clad steel round wire use
Applicable to the horizo
nment of the general enviro
nment and the special enviro
nment such as wet, saline, and acidic soils that produce chemically corrosive media, such as working grounding, protective grounding, lightning protection grounding, and anti-static grounding. The mechanical properties of electroplated copper clad steel are more pleasing, and the corrosion resistance of co
ntinuous cast copper clad steel is superior. It is recommended to use co
ntinuous casting copper clad steel grounding wire for those with serious corrosion co
nditions and those with low mechanical stress requirements. : Horizo
ntal grounding pole in a very acid environment), use different types of grounding wire according to the specific situation.
