Summary of YB American Type Compact Substation switch cabinet :
The YB compact substation is an important unit of the power supply network. It has the features of controlling, protecting, power transforming and power distributing for high voltage. The high voltage load break switch and fuse are put into the transformer oil. So it has two kind structures that are: single and sharing substation with transformer. There are the oil thermometer, pressure gauge, pressure release valve, oil drain valve monitors in the fully sealing oil box. The way of power supply is ring main unit mode, terminal mode and bi-power mode. For the fact of the domestic power supply network, our company produces the insert type dry fuse, if the fuse fused, it won't affect to the transformer oil. There are three kind of YB substation: standard model, strengthen model, integrated model .
