接地棒市场价格铜包钢接地棒厂家
采用铜包钢系列做接地材料的优势
采用铜覆钢接地棒，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，因而接地棒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。
镀铜接地棒生产工艺
镀铜接地棒的四维电镀法采用国内先进的纳米碱性预镀铜技术。其原理是通过构建空气动力场环境，对镀液中络合物与Cu2+形成纳米级粒子团的密度与沉积速度进行精微控制，在铜和钢之间构筑一种新型纳米级粒子沉积模型，阴极金属沉积形成纳米级碱性铜粒子晶镀层结构，纳米级晶镀层的致密性好并具有高活化表面，大大加强了镀层间的亲和力，使结合力达到较佳标准。成品具有优良的机械强度、延展性和耐腐蚀性能。

Advantages of using copper-clad steel series as grounding materials
Copper-coated steel ground rods are generally not reactive with acids, bases, and salts due to poor metal reactivity. 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 ground rod resistance does not change with time. The change has been made to achieve maintenance-free, and the life expectancy is generally 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.
Copper plating ground rod production process
The four-dimensional electroplating method of copper-plated ground rods adopts domestic advanced nano-alkaline pre-plating 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.
