ซัพพลายเออร์ที่ผ่านการตรวจสอบแล้ว ZGS type combined transformer, namely American type transformer station, is a transformer that combines transformer body, switchgears, fuse, tap changer, low-voltage distribution device and other relevant auxiliary equipment. It can meet the requirements of users' electric energy measurement, reactive compensation, low-voltage shunt and other configurations. ZGS type combined transformer is an independent complete set of power transformation and distribution device with the rated capacity of 63-1600kVA in the AC 50Hz / 6-10kV power grid, which can be used both outdoors and indoors. It is widely used in industrial parks, urban residential areas, commercial centers, high-rise buildings, temporary construction sites and other places.
