受土质等条件影响，防雷接地电阻常偏高，不利于散流；角钢接地极，易被腐蚀，接地电阻随时间变化大。在某钢厂防雷技术中，使用降阻剂；采用新型铜包钢及合理的接地方式等措施。系统使用结果表明，使用降阻剂改良土壤，接地电阻控制在3．6Ω左右；用铜包钢接地极，1年后其阻值变化0．1Ω，接地电阻几乎没有变化，性能稳定。

Affected by the soil and so on, lightning protection and grounding resistance is high,does not favor the loose stream;angle steel grounding electrode is easy to be corroded,and grounding resistance varias high with the time.The author in a steel mill in lightning protection tech-nology,using resistance reducing agent;using a new type of copper clad steel and reasonable grounding means.The results using in the system showed that:the use of resistance reducing agent in soil improvement,grounding resistance control in 3.6 Ω;with copper clad steel grounding elec-trode,a year after its resistance change 0.1Ω,and grounding resistance with almost no change,so the performance is stable.
