The “kiosk-style” substation does not imply that its enclosure is physically shaped like a pavilion; rather, the term is used to highlight its characteristics of overall compactness and minimal footprint. This type of outdoor, integrated substation integrates medium-voltage switchgear, low-voltage distribution equipment, and associated auxiliary devices within a single enclosed housing. The transformer, however, is arranged externally—left exposed rather than fully encased—to rely on natural ventilation for superior heat dissipation. The enclosure is typically constructed from metal or non-metallic composite materials, offering protection against rain, dust, and corrosion, as well as impact resistance; it also serves to provide thermal insulation and noise reduction.
The entire assembly is fully prefabricated, assembled, and commissioned at the factory. Upon delivery to the site, it simply needs to be mounted onto a pre-prepared, simple foundation; this eliminates the need to construct a traditional civil-engineered substation building, allowing the unit to be put into immediate operation. Essentially a type of pre-fabricated power distribution unit, it integrates the functions of voltage transformation, power distribution, operational control, and protection into a single, compact structure, making it particularly well-suited for direct outdoor deployment.
