       ZGS11 series of prefabricated substation is used in the 10~12KV ring net power supply, double or terminal power supply system as substation, distribution, measurement, compensation, controlling and protection devices. The inner of the prefabricated substation has not only the transformer, but also has 4-position load switch, 2-position load switch, backup protection fuse and plug-in fuse on the HV side. The low-voltage side can be equipped with electrical controller, distribution electric apparatus, and compensation device and electricity meter as per the user. It applies the transformer oil as the insulation and arc extinguishing media.

       ZGS11 series of prefabricated substation is developed on the combination of the most advanced technology and the actual state situation. The transformer is S9 type, and the whole products has the features of small size, easy installation, low noise, low loss, anti-theft, strong overload ability and safety, and therefore it is suitable for the new area, green belts, parks, railway station, docks, hotels, construction sites and airports.

       ZGS11 series of prefabricated substation meets the requirements of its components standard and GB/T 17467-1998 (HV and LV prefabricated substation) and the requirements of OZTC.536.009 (technology) and IEC61130:1995 (prefabricated substation).
