General

This substation has 3 main compartments, that is:
The transformer compartment,
High/Medium Voltage Switchgear Compartment and
Low Voltage Switchgear Compartment.

High Voltage & Low Voltage compartments are with completed function.

1. High Voltage compartment has various power supply methods when testing power supply at 1 time, it also can be installed with High Voltage testing appliances to reach the demand of High Voltage testing.  

2. The transformer compartment can use S7, S9, S11, or other low-loss oil-immersed transformers, or dry transformers.  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 functions like light distribution, power distribution, reactive power, electrical power testing..etc to improve the power distribution quality and satisfy the user.

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 High Voltage controlling, protection and converting ,distribution.. it is used in 3 phase AC 50Hz and rated current max 1600KVA transformer. It is widely used in industrial and mining enterprises, residential quarters, hospitals, malls, high-rise buildings, and other distribution systems.

For this substation, we mainly produce & export 11KV, 15KV,20KV,24KV, and 33KV types.

For customized special type, once we get clear technical data or single line diagram(SLD), we also can make it.
