Product Description

150 Kva 3 Phase Pad Mounted Transformer Oil Immersed Step Down 12.47 KV To 480V





We 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 S11,S13 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 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.
