Note 1Transformers with rated capacity less than 31500 kVA and other voltage combinations can also be provided as required.
Note 2 Transformers with low voltage of 35 kV or 38.5 kV can also be provided as required.
Note 3 The non-splitting structure is preferred. If there is any requirement for operation, sub-connectors can be set up.
Note 4 When the average annual load rate of transformer is between 45% and 50%, the maximum operating efficiency can be obtained by using the loss value in the table.
