the specification of the distribution transformer substation
ZGS series prefabricated substation, also know as the American substation, is a complete set of new power transformer equipment developed by our company on the basis of transformation of national urban network making the optimal combination for the oil-immersed sealed power transformer and high and low voltage electrical components. Through structure optimization, the switchgear shall be miniaturized to extreme extent which greatly reduce the occupied area of the combined transformer whose volume is only equivalent to 1/3-1/5 of the European box-type transformers with such advantages as small volume, low noise, reliable power supply, reasonable structure, blexible for installation, easy for operation and capable of going deep into the load center to maximum extent, etc. It is widely used in residential quarters commercial centers stations industrial and mining enterprises airports railroads schools hospitals, high-rise buildings and places
