Abstract: Substation construction using prefabricated construction is the development trend of the future. In this paper the structural type of prefabricated substation construction, choice of wall plate,and building roofing system were comparatively analyzed and researched, put forward a solution based on prefabricated building embedded pipe; Through research and engineering application, presented the design schemes of different structure system assembled and advantages. The results can be used as a prefabricated substation architectural design of a kind of reference, provide the reference for application of prefabricated construction in the future.
