PRODUCT DESCRIPTION
The YBW series prefabricated substation is a combination of high-voltage electrical equipment, a transformer, low-voltage electrical equipment, etc., into a compact, complete power distribution device, used in urban high-rise buildings. Urban and rural buildings, residential areas, high-tech development zones, and small and medium-sized factories. Mining oil fields and temporary construction, and electricity use. etc., for the distribution and distribution of electrical energy in the distribution system
The YBW series prefabricated substation has the characteristics of a strong set. Small size.compact structure. Sate and reliable operation, convenient maintenance, and movable. Compared with a conventional civil substation, the same capacity box-type substation usually covers an area. Lt is only 1/10-1/5 of the conventional substation, which greatly reduces the design workload and construction volume and reduces the construction cost. In the power distribution system, the thousand-ring network power distribution system can also be used, or the thousand-double power source or the radiation terminal power distribution system can be used. It is a new type of equipment for the construction and improvement of urban and rural substations.
YBW series prefabricated substation meets the national standard of GB/T17467-1998 "High Voltage / Low Voltage Prefabricated Substation"
