Rating:
Rated voltage : HV equipment10KV and 12KV, LV equipment 0.4 KV.Rated current :HV equipment 630A, LV equipment 1500A.
Application:
Yb27 series substation is an American type combined substation with function of high voltage control, protection, power transformation and distribution. Usually used in urban and rural power distribution system. The high voltage load switch and high voltage fuse of this product are installed in the oil of the transformer, with the two structures: in same case with the transformer and in different case with transformer. It can be used in high-rise buildings, building in urban and rural areas, residential communities, high-tech development areas, small and medium size factories, mining areas, oilfields, temporary features sites, and
other premises.
Standard: IEC1330
