ZGS outdoor three phase dyn11/yyn0 pad mounted transformer
pad mounted transformer
General specs of pad mounted transformer
ZGS11 series of pad mounted transformer is used in the 12KV ring net power supply, double or terminal power supply system as substation, distribution, measurement, compensation, controlling and protection devices. The inner of the pad mounted transformer 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. pad mounted transformer applies the transformer oil as the insulation and arc extinguishing media.
ZGS11 series of pad mounted transformer 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 pad mounted transformer meets the requirements of pad mounted transformer components standard and GB/T 17467-1998 (HV and LV pad mounted transformer ) and the requirements of OZTC.536.009 (technology) and IEC61130:1995
