This substation body can be metal material, stainless steel material , non -metal material ...as customers ' requirement.
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 single line diagram(SLD), we also can make it.

Jiangxi Yawei Electrical Co.,Ltd. professional custom made package substations for all over the world.This substation has 3 main compartments. There are transformer compartment, high/medium voltage switchgear compartment and low voltage switchgear compartment.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 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.
