YBW-12 preinstalled type transformer substation. This series of pre-installed type transformer substation is a high voltage switch equipment, power distribution transformer, the low voltage power distribution equipment according to user requirements, according to a line scheme by the factory, the outdoor type prefabricated forming complete set of equipment.
High voltage switch equipment can choose: ABB, SIEMENS, F&G SF6 of ring net switch cabinets or ISARC and FN type load switch cabinet, can be a terminal or ring network power supply unit. Transformer can choose SC9 type dry type transformer or S9 oil-immersed transformer, low voltage distribution device adopts imported or domestic famous quality low pressure switch, circuit breakers, ac contactor, each independent units installed perfect control, protection, charged display and stood with lighting system. The cabinet can be installed temperature, humidity automatic control device and forced ventilation system.
This series of pre-installed substation suitable for 7.2 ~ 40.5 kV power supply and the ring network terminal power supply system of city, high buildings, residential area, mines, the subway, dock, hotels, malls, parks, station, school, hospital, oil field, airports, ports and temporary power supply facilities, such as wind power system of power grid connection, road lighting power supply, etc.
