YBM, YBP series of outdoor high voltage 1000kva electrical substation is complete set, small sized, compacted structure, running safely, easy maintenance, and mobile. And it 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 outdoor high voltage 1000kva electrical 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 of outdoor high voltage 1000kva electrical substation
