YBM, YBP series of compact distribution substation is the combination of the HV electrical apparatus, transformer, and low voltage transformer equipments and therefore is used in the high-rise buildings, residential districts, urban and rural construction, hi-tech development zone, small and medium size enterprise, mine and oil fields and the temporary construction sites to receive and distribute the power. YBM, YBP series of prefabricated substation is complete set, small sized, compacted structure, running safely, easy maintenance, and mobile. And compact distribution substation only takes the 1/10-1/5 of the space of the same capacity of civil construction distribution, and therefore greatly reduces the construction cost. It can be used in the ring net distribution system, double power distribution system or radiator terminal distribution system. It is the new complete set equipment used for rural and urban substation construction and reformation. YBM, YBP series of compact distribution substation is fully in accordance with the standard of SD320-1992 (the technology of Boxes substation) and the standard of GB/T 17467-1998 (HV/LV prefabricated substation). The shell is made of non-metal, composite board or the steel sheet as per the users. 3. Technical parameters
