The prefabricated smart substation, also known as a prefabricated cabin, is a further development of smart substation technology. To standardize construction, improve project quality, safety, and efficiency, the State Grid Corporation has initiated the construction of standardized, delivery-oriented smart substations. The technical principles include 'standardized design, factory-processed, mechanized construction, and prefabricated assembly'. This standardization not only effectively shortens construction periods, improves project quality, and reduces construction cycle costs, but also promotes environmental protection, enhances smart substation efficiency, and boosts power grid construction capacity. It leads substation construction towards a path of high technological content, low resource consumption, minimal environmental pollution, and fine-tuned construction.

• Highly Integrated: Pioneering one-stop solution for DC input, inversion, and boost output; factory-installed and commissioned, with on-site overall hoisting, completing transportation, installation, and maintenance in one go.
• Strong Adaptability: Fully considers requirements for exhaust and heat dissipation, wind and sand resistance, rain and snow protection, corrosion resistance, and low-temperature tolerance.
• Stable Performance: High integration, fewer failure points, improving performance stability; can operate stably with 20%-50% overload (for plant oil type).
• High Profitability: Reduces AC cable investment, centralizes optimization of circuit breakers, lightning protection, power supply, and monitoring equipment; small footprint and low construction difficulty.
• Can replace the traditional "MW room + photovoltaica box transformer" model.
