Advantages of a three-phase oil-immersed transformer Sz11
-The SZ11 on-load voltage regulating transformer is an oil-immersed transformer that can perform manual or automatic polar voltage regulation without power failure.
-Both the high and low voltage windings are wound on a high-strength insulating cylinder, which improves the short-circuit resistance of the transformer.
-The coil heating is low and the overload capacity is strong.
-Low noise, reliable operation, simple installation, etc.
