Modular substation adopts standardized assembled modular design, consisting of independent functional modules including high voltage unit, transformer unit and low voltage distribution unit. Modules are prefabricated and tested in factory, enabling flexible combination according to project power demand. Features convenient transportation, quick on-site assembly and scalable capacity. Equipped with intelligent monitoring, fire protection, ventilation and anti-corrosion structure. Widely used in photovoltaic power plants, battery energy storage stations, industrial parks and urban power grid upgrading. Modular layout can be freely expanded to meet varying load requirements for global renewable energy and power distribution projects.
