镀铜钢接地材料优点:
Advantages of copper plated steel grounding material:
1.镀铜钢接地材料利用表层厚达0.254mm铜层的防腐性，同时采用分子间相互渗透的电镀工艺，具 备了优异的防腐性能。可保证地网50年免维护，和传统材料相比有良好的经济性能并满足全寿命 设备周期管理，符合新材料新工艺新设备范畴。
1. The copper plated steel grounding material has excellent corrosion resistance by using the anti-corrosion property of 0.254mm copper layer on the surface and the electroplating process of mutual penetration between molecules. Compared with traditional materials, it has good economic performance and meets the life cycle management of equipment, which is in line with the scope of new materials, new processes and new equipment.
2.在高频接地或雷击电流作用下，产生集肤效应，让镀铜钢接地材料据有接近于纯铜的导电性。
2. Under the action of high frequency grounding or lightning current, skin effect will be produced, which makes the copper plated steel grounding material possess the conductivity close to that of pure copper.
3.垂直镀铜接地材料安装方便快速，免开挖省时省力。通过连接，可实现任意深度并利用地下含水层，降阻效果明显，同时无需额外钻深井，从而减少变电站占地面积。
3. The installation of vertical copper plating grounding material is convenient and fast, without excavation and saving time and labor. Through connection, any depth can be realized and the underground aquifer can be utilized. The effect of resistance reduction is obvious. At the same time, there is no need to drill deep wells, so as to reduce the occupied area of substation.
4.水平镀铜钢接地材料为绞线，成卷供货，铺设时接头少，穿管弯曲方便。绞线每股单独电镀，铜 层厚度高达0.3mm以上，导电性能优异。
4. The grounding material of horizontal copper plated steel is stranded wire, which is supplied in coils. There are few joints when laying, and it is convenient to bend through the pipe. Above 0.3 mm copper layer per strand.
