The construction conditions of transmission lines are becoming more and more difficult. It is necessary to find new ways to reduce the grounding resistance of poles and towers at high soil resistivity and small construction area. Conductive cement samples with graphite, stainless steel fibers, and their mixtures as conductive phases materials were prepared, the resistivity, flexural strength and compressive strength were tested, compared and analyzed. The graphite and stainless steel fiber conductive cement with better comprehensive performance was selected out for tower grounding. The application schemes of conductive cement for tower grounding were designed and compared, the partial wrapping scheme was selected and its application methods under different soil resistivity was analyzed. The analysis results can provide theoretical basis and guidance for the application of conductive cement in transmission tower grounding, the feasibility of scheme is proved by the field application.

传输线的施工条件变得越来越困难。在高土壤电阻率和较小建筑面积的情况下，有必要寻找新的方法来降低杆和塔的接地电阻。制备了以石墨，不锈钢纤维及其混合物为导电相材料的导电水泥样品，并对其电阻率，抗弯强度和抗压强度进行了测试，比较和分析。选择了综合性能更好的石墨和不锈钢纤维导电水泥进行塔架接地。设计并比较了导电水泥塔接地的应用方案，选择了部分包裹方案，分析了在不同土壤电阻率下的应用方法。
