630kVA Box-Type Substation Transformer (European-Style Substation)

A box-type transformer (abbreviated as “box transformer”) is a complete distribution equipment that integrates transformers, high- and low-voltage switchgear, and other components within one or more sealed enclosures. Its compact size and easy installation make it particularly suitable for scenarios with limited space or requiring rapid deployment, such as urban grid upgrades, factories, construction sites, or new energy projects.

Its core structure comprises high-voltage, transformer, and low-voltage compartments, featuring a fully sealed design that provides protection against moisture, dust, and rodents, ensuring safe and reliable operation. Compared to traditional brick-and-mortar substations, box transformers offer shorter construction cycles and reduced footprint, establishing them as an economical and efficient solution in modern power distribution systems.
