YBM(P)-12.0.4 mobile substation HV electrical substation
General
YBM(P)-12/0.4 series prefabricated substation is a kind of compact power distribution device that integrates high voltage electrical devices, transformer, low voltage electrical devices together. It can be used in high-rise buildings,building in urban and rural areas, residential communities, high-tech development areas, small and medium size factories, mining areas,oil fields, temporary construction sites, and other premises, and can also be used for acceptance and distribution of power in power distribution system of 6-10kv,50Hz.
This product is characterized with features including high integrity,small size ,compact structure, sage and reliable operation, convenient maintenance,portable,etc. Compared with conventional transformer requiring civil work, the prefabricated transformer with same capacity need only one-tenth to one-fifth of the floor area for conventional transformer so that the construction expense is reduced significantly. It also can be used in ring net power distribution system and double power supply or terminal power distribution system.
This product complies with standard of IEC1330,Technical specification for box-type transformer.
