Outdoor 4 Wheels Box Type Electrical Mobile Transformer Substation

Boerstn  Outdoor Electrical Mobile Substation  (on 4 wheels) ,it includes 4 main parts as below

1.High voltage compartment

2.Transformer compartment

3.Low voltage compartment

4.mobile trailer 

Boerstn electric co.ltd can professional custom make  this substion as user and customers requirement under their drawing (Single Line Diagram ,SLD ) and need for their projects.

HV & LV compartments are 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 ,S11 or other low loss oil immersed transformer ,or 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.

The substation shell /Enclosure availiable can be in any metal or non-metal materials, like stainless steel , black steel ,wood, cement tiles, Aluminium ..etc chosed by users 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. Rated voltage max. reaches 40.5KV. For customized special substation , after we get detailed specifications or single line diagram (SLD),we can go to design and manufacture it .It is widely used in industrial and mining enterprises, residential quarters, hospital, mall, high-rise buildings and other distribution systems.
