Note: The 220KV power transformer of detail specification should negotiate with us, it not public in the website

1 According to the demands of consumers, we can manufacture products which model is not Included In tables sheet. Performance parameters are decided according to customers demand

2 MV value can be different from those our tables sheet, HV tap changing can be made asymmetrically

3 impedance voltages can provide different values from those In above tables

4 Final dimension of transformer should be subject to drawing confirmed by both sides after contract signed
