Product Description
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.
1. Small volume, compact structure, small floor area and convenient installation.
2. Low loss, low noise, low temperature rise, strong load capacity beyond rated capacity, strong short-circuit resistance.
3. Totally enclosed and insulated structure, safe and reliable operation.
4. The wiring mode is flexible, which can be used in both terminal system and ring network system. The conversion is convenient and the reliability of power supply is improved.
5. Simple operation, convenient maintenance, short production cycle and low project cost.
