Prefabricated substation are highly susceptible to external environmental and mechanical factors due to long-term exposure to the outdoors. On account of the large structure, the prefabricated substation box is difficult to conduct on-site tests and indoor test analysis. In this paper, according to the topography and climatic characteristics of north western China where prefabricated substation box is used in, finite element analysis method is developed to analyze its performance under wind and
