Busways (or bus ducts) are prefabricated electrical distribution systems offering flexible, high-current power transfer for industrial plants, high-rise buildings, and data centers. Selecting the appropriate type requires understanding key classifications and application-driven parameters.

Box-type Transformer, abbreviated as "box transformer", literally means that the entire voltage transformation equipment is installed in a box, just like building a "house" for these devices in advance. This "house" is moisture-proof, rust-proof, rat-proof, and heat-insulating, making it an excellent enclosure for power transformation equipment. Compared with traditional substations, they feature a small footprint and environmental friendliness. It is applicable to 10/0.4KV three-phase AC systems with rated voltage, serving for line connection and power distribution. It is particularly suitable for urban network construction and transformation, emerging as a new type of substation following civil-engineering substations.
