A prefabricated substation (also known as a box-type transformer) is a complete set of equipment that integrates a transformer, high-voltage switchgear, low-voltage distribution equipment, and protection and measurement systems into a single enclosure. Its core features are high integration, compact structure, and convenient installation, making it suitable for urban power distribution and various temporary or decentralized power supply scenarios.
Its compact size and flexible layout are advantages. The box-type transformer's integrated design concentrates previously dispersed substation equipment within the enclosure, significantly reducing space requirements. This makes it ideal for space-constrained environments such as urban residential areas, commercial centers, parks, and construction sites. Furthermore, it can be flexibly deployed and moved according to site needs.
It boasts a short installation cycle and simple construction. The enclosure is fully integrated and commissioned in the factory. After transportation to the site, only foundation installation and cable connections are required for operation. Compared to traditional civil engineering substations, this significantly shortens the construction period and reduces construction complexity and costs.
It offers high safety and convenient operation and maintenance. The enclosure has excellent protective performance, typically featuring dustproof, rainproof, corrosion-resistant, and anti-misoperation designs, enabling it to adapt to complex outdoor environments. Simultaneously, the enclosed internal structure reduces the risk of external personnel coming into contact with high-voltage equipment. Maintenance is also more centralized, making fault location and repair more convenient.
