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.
Introduction
ZGS Series transformer is a kind of set of equipment which assembles the MV switch apparatus, transformer, LV distribution equipment together according to fixed connection scheme. This series substation is suitable for neighborhood unit, hotel, large-scale work site and high building.
1. Chassis:
Made of standard industrial groove steel, angle irons welded together. It has features of reasonable design. It is anti-corrosion, anti-rust and chemical surface treated. It is suitable for integral lifting.
2. Wall:
Made of national standard industrial construction materials. Applies alkali-proof fiber glass reinforced special cement and other additives and lining of steel structure skeleton.
It has features of bending resistance,tensile strength, easy maintenance, beautiful onfiguration, good compact resistance, weather proof, anti-corrosion and high completeness.
The pollution grade is suitable forIII grade. The protection grade is IP32DH and it can withstand strong external mechanical impact.
The ventilation grid and aluminum alloy shutter effectively reduce the temperature rise from sunshine and equipment operation.
The external can be decorated with cultured stone, glazed brick and other beautiful materials.
3. Top cover:
The top cover is steel skeleton prefabricated of high strength and good rainwater proof property.
It is of movable top cover. It is easy to lift.
The external configuration has many types like flat top, antique type,
ridge type and villa type. It can be designed as per client requirements.
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.
