Advantages of a three-phase oil-immersed transformer S20-630KVA

-The core of silicon steel is made of 0.18 ~ 0.3mm orientation silicon steel sheet stacked by punching and shearing, which has good stability.

-The coil is made of pure copper. The acetal enamelled wire is used for high voltage and oxygen-free copper conductor or copper foil for low voltage to improve the short-circuit resistance.

-The Dyn11 connection symbol is used to avoid the influence of higher harmonics. It provides high resistance against uncompensated load and improves the quality of power supply.

-Vacuum oiling is adopted by the transformer to remove bubbles in the core and ensure stable insulating property.
