ZGS 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 description
The combination transformer is characterized by reliable power supply, reasonable structure, quick installation, flexible and easy operation, small volume, low construction cost, etc. it is suitable for outdoor and indoor use, and is widely used in industrial parks, residential quarters, business center and high risers.
Feature
Small volume, compact structure, reliable power supply and easy for installation; it can realize single power supply, double power supply, or ring net supply, with double-fuse protection, low running cost.
The casing surface is treated by electrostatic painting and has good wearing resistance. It is applicable to both ring network and single/double power supply, is convenient for shifting, and can enhance the reliability of power supply.
The transformers adopts environment-friendly S11 series spiral core, non-excited voltage regulation, full-enclosed type, featuring energy saving and low noise. The amorphous alloy transformer is also available if required by clients.
HV load switches and protective fuse are placed in oil filled iron tank, and the tank is of full-enclosed structure.
The LV room is provided with watt-hour meters, voltmeter, and breakers of four outgoing lines, reactive power compensation can also be provided if necessary.
It uses S11 series spiral core transformer amplifier, its idle loss is 30%-40% lower than S9, and noise 7-10Db lower than S9.
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.
