The transformer bushing is the outlet device that leads the high and low voltage leads inside the transformer to the outside of the oil tank. It has a specified electrical strength and sufficient mechanical strength. The voltage level of the coil connected to the bushing determines the insulation structure of the bushing, and the operating current of the bushing determines the cross-section of the conductive part and the structure of the terminal.
