> Structural Features
The S11 series reduces the basic no-load loss of the S9 series by an average of 30%, reduces the average temperature rise by 10K, and the service life of the product more than doubles, even under overload conditions of 20%, it can still operate for a long time; The operating noise of the product is reduced by an average of 2-4 dB.
> Main Technical Parameters
6kV, 10kV class 200kv· A~2500kV· A Three-phase dual-winding on-load voltage regulation and distribution transformer
Note: When the annual average load rate of the transformer is between 35%~40%, the highest operating efficiency can be obtained by using the loss value in the table.
