General
ZBW series of combined substation is the combination of the high-voltage equipments, transformer, and low voltage electrical apparatus. It is used in the high-rise building, residential districts, urban and rural construction, hi-tech development zone, small and medium size enterprise, mine and oil fields and the temporary construction sites to receive and distribute the power. T
ZBW series of combined substation is complete set, small sized, compacted structure, running safely, easy maintenance, and mobile. And it only takes the 1/10-1/5 of the space of the same capacity of civil construction distribution, and therefore greatly reduces the construction cost. It can be used in the ring net distribution system, double power distribution system or radiator terminal distribution system. It is the new complete set equipment used for rural and urban substation construction and reformation.
ZBW series of combined substation is fully in accordance with the standard of GB/T17467-1998 (high voltage/ low voltage prefabricated distribution) and the standard of IEC1330
