Box-type Substation
The YB series AC combined substation is a fully enclosed, movable structural unit that integrates high-voltage electrical equipment, distribution transformers, and low-voltage distribution equipment into a single system, achieving the functionality of a substation. It features compact size, safe and reliable operation, easy maintenance, and mobility. Compared to conventional civil substations, a box-type substation of the same capacity typically occupies only 1/10 to 1/5 of the land area, significantly reducing design and construction efforts and saving construction costs.
