Note 1: On-load voltage regulating transformer, temporarily provide step-down structure products.

Note 2: The capacity allocation of high, medium and low voltage windings is (100/100/100)%.

Note 3: The label of the coupling group can be YNd11y10 as required.

Note 4: The-10% tap position is the maximum current tap.

Note 5: According to user requirements, the medium voltage can be different from the voltage value in the table or tap.

Note 6: When the annual average load rate of the transformer is about 47%, the highest operating efficiency can be obtained by using the loss values in the table.
