This series of wiring complete plants is produced on the basis of summarizing the
circulate situation of box-substation in the market and the request of city network
alteration to the power distribution network automatic. It is developed by Tianjin
electrical transmission design research institute who has combined hundreds of
corporations, and our company is one of the designer member.
XBZ1 intelligent box-substation is suitable for China characteristic which has absorbed
the advantages of American box-substation, Europe box-substation and homemade
box-substation. It has adopted the new material, new technique, advanced apparatus
and high and low voltage automatic technology. Hereinto, high voltage (12kV) can
satisfy the power department's requirement of power distribution network automatic,
low voltage (0.4kV) can satisfy the management requirement of district intelligent.
Characteristics:
1) The nonmetal cover has strong capability of mechanism resisting
bending, impacting, burning and can resisting cold, crack, and
corrosive, the mechanism endurance is above 50 years
2) The cover is beautifully and can match with the ambient; it is the
optimal substitution of the traditional metal box-substation
3) SF6 load switch has largely enhanced the safety of the circulating and
operating, so it is conveniently install and has high economy benefit
