Product Description

500kva Three Phase Pad Mounted Transformer Step Down 12470v To 208v





The three phase pad mounted transformer immerses the load switch and fuse on the high voltage side of the transformer with the core and windings of the transformer in the same oil tank, has the advantages of advanced structure, reliable performance, energy saving and consumption reduction, flexible use, strong adaptability, and economical advantages.



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.
