Through establishing the heat transfer model of composite wall, the insulating layer of the top and the bottom, and the anti-static floor using the thermodynamic simulation software, the establishment of the two power equipment cabinet and device box, gave box rated power by the entity model, the extreme temperature insulation performance was analyzed. The corrosion resistance of the prefabricated cabin was analyzed in the polluted area in Inner Mongolia. The r
