ZBW(YB)17-10 Series HV/LV Prefabricated (American type)Substation
Applications
The combined American box change is a transformer body, high voltage load switch, fuse and other components.
It is placed in the transformer oil tank. Because it is immersed in oil, the volume of the components is greatly reduced, the structure is more compact, and the installation is convenient and flexible. Fully insulated, fully sealed structure, safe and reliable, easy to operate, maintenance free. Widely used in residential quarters, high-tech centers, factories and mines, airports, stations, schools.
Product introduction
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.
Service environment
a)Air temperature:Maximum temperature:+50oC; Minimum temperature:-55oC
b) Humidity: Monthly average humidity 95%; Daily average humidity 90% .
c) Altitude above sea level: Maximum installation altitude: 2500m
d) Ambient air not apparently polluted by corrosive and flammable gas, vapor etc.
e) No frequent violent shake
Main Designation Characteristics
l The crust of the substation is designed according to the foreign advanced technology and physical reality. We provide many kinds of crust material such as aluminum alloy steel composite stainless steel board and non metal material(glass fiber).
l The HV side use charge switch or vacuum circuit breaker. The transformer could be oil type hermetically-sealed type and dry type.
l The proof of the box is double layers structure and between the layers is filled with foam.There are independent boards in HV and LV room, and in the transformer room will install auto thermal controller heater and cooling equipment.
Note: we offer special customized products according to client's requirement.
Scope of application:
1.Urban public power distribution system,in the residential area,when downtown street load increases,and need to increase the transformer capacity.
2.Temporary power supply of construction site:existing buildings,the need to transformer or increase the use of electrical equipment,field operations and outdoor workplace power supply,such as oil,mining,port terminals,stations and so on.
