A box substation is a box type substation, which simply means installing a substation into a house made of colored steel plates, and the box type substation can be moved and relocated as a whole. The earliest substations were built on the ground or underground, and after completion, they could not be relocated as a whole. Box transformers could be relocated, with distribution facilities such as transformers, high-voltage distribution cabinets, or low-voltage distribution cabinets inside. The box transformer foundation is the installation foundation of this box type substation, which is designed according to the size, weight, cable installation, operation, maintenance and repair needs of the box transformer. Box transformer foundation is also commonly known as the building foundation of inverters and box transformers. By embedding steel plates on the foundation of the box transformer, a balanced and stable foundation is provided for the installation of the inverter and box transformer. There is a passage through the cable at the foundation of the box transformer, providing a concealed passage from the combiner box outgoing line to the inverter incoming line and a passage from the inverter outgoing line to the low-voltage side incoming line of the box transformer
