A prefabricated substation, commonly known as a box-type substation or compact substation, is an integrated power distribution unit designed for voltage transformation and energy distribution in electrical systems. It combines high-voltage switchgear, a power transformer, and low-voltage distribution equipment within a modular, weatherproof enclosure. This compact structure allows for easy installation, relocation, and maintenance while minimizing land use.Key components include high-voltage compartments (for incoming power), transformer units (for voltage conversion, e.g., 10kV to 400V), and low-voltage panels (for distributing electricity to end-users). Constructed with robust materials, the enclosure ensures protection against environmental factors such as dust, moisture, and corrosion, often meeting IP34 or higher protection ratings. Advanced models feature smart monitoring systems for real-time data collection and remote control.
Prefabricated substations are widely used in urban grids, industrial parks, residential complexes, and renewable energy projects due to their adaptability, safety, and cost-effectiveness. Their plug-and-play design reduces on-site construction time, making them ideal for temporary or space-constrained installations. By enhancing grid reliability and operational efficiency, box-type substations play a vital role in modern power infrastructure
