Abstract The windings of power transformer with different voltage levels are immersed in the oil tank. The winding is led out to the outside of the oil tank via a cable or bushing which connecting with other equipment to realize the transmission of electric energy. This paper introduces several kinds of lead-out methods of transformer winding, such as capacitance bushing, cable and pure porcelain bushing. Also their applicability, advantages and disadvantages are analyzed.
