ZGS11 combined power substation (American Pattern)

1)small size,easy installation,easy maintenance 2)low noise,low loss 3)anti-theft,strong overload ability,safe

ZGS11 series of prefabricated substation applies to 12KV ring power supply, dual power supply or the terminal power supply system to use as the substation, distribution, measurement, compensation, control and protection devices, and it is commonly known as the American pattern box type substation. In addition to the inside transformer, the high voltage side of the prefabricated substation also installs the four-position load switchers, second-stage load switches, back-up protection fuse and plug-in fuse; the low voltage side can install the control electrical appliances, power distribution electrical equipment, compensation devices and energy metering devices according to user's requirement. It uses the transformer oil as the insulation and interrupter media. The ZGS11 series of prefabricated substation is developed on the basis of the latest foreign advanced technology and actual situation.S9 type ZGS11 series of prefabricated substation has the features of small size, easy installation easy maintenance, low price, low loss, anti-theft, strong overload ability, and safe. It can be used in the new residential, green belts, parks, railway station, docks, hotels, site, airports and other places. The performance of the product meets the respective components requirements and the product also comply with GB/T17467-1998 "high-voltage/low voltage prefabricated substation" and the product itself OZTC.356.009"technical conditions" and refers to the relative standard of the IEC 61130:1995 "prefabricated substation".
