Note: 1, To transformers whose rated capacity of 500kVA and below, load loss in the table above the diagonalis suitable for Dyn11 or Yzn11 connection group,

the load loss below the diagonal suitable for YynO connection group.

2, according to user needs, can provide transformer with high voltage tap range

3, according to user needs, can provide transformer with low-voltage of 0.69kV .

4, if the user needs, can also choose other loss values.

5, due to the continuous update of the product, weight &size in the table may changes.Most correct Dimension chart will be provied when making order.
