European-style box-type substation, mainly featuring a mesh-shaped structure, integrates high-voltage and low-voltage switchgears with transformers into an outdoor cabinet. It not only has a clear internal layout but also integrates numerous components such as conventional medium-voltage switchgears, ring main units, low-voltage cabinets, and transformers. Generally, dry-type transformers are used (a few use oil-immersed transformers), which are characterized by advanced and reliable technology, factory prefabrication, high automation, and flexible combination methods.
