It is the key embodiment of the application of new technologies, new materials and new equipment in smart substations. The prefabricated cabin substation means that the entire substation is composed of "containers". All switch cabinets, primary and secondary equipment and cabins are prefabricated in the factory. After installation and commissioning in the factory, they can be directly hoisted on site and can be used like Lego blocks. In order to ensure normal ventilation inside and outside the prefabricated cabin and prevent the electrical equipment inside from working in an overheated environment for a long time, ventilation windows are often required on the cabin.
