550kV Oil-SF6 OIP Transformer bushing

Oil-SF6 OIP condenser transformer is mainly used as connector for oil power transformer and GIS or in SF6 bus. One end of bushing is in SF6, the other end is in SF6 during operation. As medium the Max. temperature for SF6 is 40C, and the pressure is less than 0.55MpaTable 1 Oil To SF6 bushing (with pressure alarm device) Nominal system voltage kV 110132150 154220330500Rated voltage kV 126145170252363550Max. phase operation voltage kV 738498.514621031760s power frequency withstand voltage kV(r.m.s) 230275340460595740Lighting impulse Withstand Voltage Full wave kV(peak) 550650750105013001800Chopped wave kV(peak) 635750865121014951930Bending load Rated current A - 510--10501300Bending load N 160016002500 Designation Type character : BDQ oil-SF6 condenser transformer bushing with short lower part,1,2,3serial NO. in designation Structure: L CT is available,1,2,3means different length for installing CT(none for free of CT)Operation condition: Ambient condition: 40 +40 (DB45) Mounting angle : Vertical
