ZBW-10 / 0.4 type outdoor pre installed substation
ZBW-10/0.4 outdoor type prefabricated substation by the high voltage distribution device, transformer and low voltage power distribution device is connected, is divided into three functional compartments (high voltage chamber, a transformer room and low-pressure chamber), and has characteristics of compact structure, standard layout, covers an area of little, installation simple, maintenance, to maximize extends into the load center, improve the quality of power supply, reduce the loss etc.. Applies to the city's high-rise buildings, hotels, villas, residential quarters, parks, factories, stations, terminals and other places ring or terminal power supply. Meet the standard: 17467-2010 GB "high and low / low voltage prefabricated substation".
