Box-type substation, also known as pre-installed substation. It is a kind of high-voltage switch gear, distribution transformer and low-voltage power distribution device.It is a kind of factory prefabricated indoor and outdoor compact power distribution equipment that is integrated according to a certain wiring scheme. It combines the functions of transformer step-down and low-voltage power distribution organically. Which is installed in a steel structure box that is moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, anti-theft, heat-insulated, fully enclosed and movable.It is especially suitable for urban network construction and renovation.It is a new type substation after the civil construction substation. The box-type substation is suitable for mines, factories, oil and gas fields and wind power stations. It replaces the original civil power distribution room and substation and becomes a new type of transformer distribution equipment.Box-type substation is also suitable for residential quarters, urban public, bustling downtown, construction power supply, etc.Users can choose box-type substation according to different usage conditions and load levels.

Description

22/0.4KV 3000KVA transformer mini substation

Outdoor Electrical Transformer Substation ,also named as package substation or Kiosk Substation, It mainly has 3 compartments as following:
1.High voltage compartment
2.Transformer compartment
3.Low voltage compartment

we can make this substion as user and customers requirement under their drawing (Single Line Diagram ,SLD ) and need.

HV & LV compartments are with completed function.
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.

The transformer compartment can be choosed S7 ,S9 or other low loss oil immersed transformer and dry type transformer. The transformer compartment has automatic start wind cooling systems and lighting systems.

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 /Enclosure mainly is made in 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 SLD ,we also can make it .
