Box-type substation, also known as prefabricated substation or prefabricated substation. Is a high pressure switch equipment, and distribution transformer and low voltage distribution device, by must wiring programme row into one of factory prefabricated households within, and outdoor compact type distribution equipment, is high pressure by electric, and transformer buck, and low voltage distribution, function organic to combination in with, installation in a moisture, and rust, and dust, and anti-rat, and fire, and anti-theft, and insulation, and full closed, and can mobile of box within, electromechanical integration, full closed run, special applies Yu city network construction and transformation, is following civil substation zhihou rise of a new of substation. Box-type substation applies to mines, factories and enterprises, oil and gas and wind power station, which replaced the original construction and distribution, substations, be a new set of power distribution units.

  Box-type substation, since late in the 1970 of the 20th century, China, France, and Germany, and the imitation of box-type substation, structurally high and low voltage switchgear, transformer, this box changes is known as European change, metaphor for high voltage, low voltage switchgear, transformer built houses. European box occupies a large space, easy maintenance.

  Since in the 1990 of the 20th century, China, United States box-type substation, structurally load switches, network switches and fuses in structure is simplified into the transformer tank is immersed in oil. Also uses oil-immersed surge arresters ZnO surge arrester. Transformer remove oil, fuel tank and radiator and exposed to the air, this box changes, called American cabinet, metaphor for hanging next to the transformer box. American cabinet structure is more compact, small footprint, maintenance inconvenient. Later derived from the load switch and fuses into the external independent high pressure transformer unit this box

  ain unit performance, although not perfect, but it's competent enough. Along with the massive urban construction, a large number of large high-rise buildings are springing up, transformation and distribution%
