    Abstract: Based on the problems such as, the incomplete forming die used for manufacturing the grounding body, the too high welding cost and the low welding efficiency, this paper designed a new multi-needle mould for vertical grounding body according to the manufacturing process of vertical grounding body. The new type of multi-needle vertical grounding body was fabricated on the basis of a new type of forming die and the grounding system realized the engineering application in Zhangzhuang substation of Jining. The engineering verification shows that the die welding process meets the requirements of the national standard with high efficiency, reliability and low cost. The process can provide certain guidance for the high efficiency and long service life of the substation grounding system.
    Key words: grounding; multi-needle vertical grounding; die technology; long service life
