The YB-Z▪D-12 Underground Compact Substation is a kind of compact substation which can be semi-underground or fully-underground. It is underground, so the noise pollution and electromagnetic radiation can be reduced. Thus, YB-Z▪D-12 Underground Compact Substation is suitable for cities with large population density. It can be used for illumination and power distribution in the street, airport, port, tour sites etc.
