FIELD: electrical engineering; power distribution. SUBSTANCE: transportable three-dimensional box-shaped module has lateral walls with doors, longitudinal solid walls, and bottom. Length of lateral walls equals 0.5 0.65 of that of longitudinal walls. Bottom has external ribs for partial support by mating ribs, trough-shaped foundation panels mounted on baseplate or on respective bearing structures of foundation. Three- dimensional module is provided with internal transversal partition that divides its interior into sections of different surface area. Smaller section accommodates power transformer guides. Larger section houses low-voltage switchgear of modular distribution transformer substation with electrical equipment and automatic load transfer cubicle. EFFECT: reduced cost of module manufacture, its maintenance charges, labor consumption, and material input. 15 cl, 4 dwg
