Prefabricated Electrical Substation Box 4000A Rated Current For Power Distribution
Features
Hengfengyou can make this substion as user and customers
requirement under their drawing/single line diagram (SLD) and need
.We design & produce this substation under the international
standard of IEC1330 ,H.V.standard IEC62271-200.
HV & LV compartment is with completed function.
1.)H.V.compartment has various of power supply methods when testing
power supply in 1 time, it also can be installed with H.V.testing
appliances to reach the demand of H.V.testing.
2.)The transformer compartment can be choosed S7 ,S9 or other low
consumption oil immersed transformer and dry type transformer. The
transformer compartment has automatic start wind cooling systems
and lighting systems.
3.)Low voltage compartment can be made according to users' need ,
it adopts fixed or assembled structure to be electrical power
supply system,it has many function like light distribution ,power
distribution, reactive power ,electrical power testing..etc to
improve the power distribution quality and satisfy the user.
This substation body mainly has metal material, stainless steel
material , non -metal material ...which can be choosed by user and
customers
This substation is a very important power distribution and supply
unit in the electrical cable power net.it is a kind of completed
set of power supply with H.V.controlling,protection and converting
,distribution.. it used in 3 phase AC 50Hz and rated current max
1600KVA transformer.It is widely used in industrial and mining
enterprises, residential quarters, hospital, mall, high-rise
buildings and other distribution systems.
For this substation, we mainly produce & export 11KV,
15KV,20KV,24KV,33KV type.
For customized special type, once we get clear technical data or
drawing,we also can make it .
Advantages
Reduced electrical losses as USS can be installed near load
centres.
Total economy in cost.
Higher degree of safety and operational reliability is achieved by
HT and LT switchgears and protective relays to avoid overloading.
Reduction in logistic cost as USS is delivered as a single unit.
Low civil / foundation cost.

Product composition
Service Centre
The shell of the box is made of aluminum-coated zinc steel plate
and container manufacturing technology, and the design is beautiful. On the premise of ensuring
the reliability of power supply, the shell color of the box-type substation is selected, so that it
is easy to be in harmony with the surrounding environment Especially suitable for urban construction.
Such as: Urban residential areas, stations, ports, airports, parks, green belt and other
densely populated areas, it can be used as a fixed substation, can also be used as a mobile
substation, with decorative and beautifying the environment.
