Product Description

European box-type transformer substation E-house Ybm-12/0.4 prefabricated substation

The Ybm-12/0.4 prefabricated substation is a type of modular substation, with another name of 'European style modular substation', is a type of compact set of power distribution substation with the components of HV electricity, power transformer and LV electricity, and it is with varied features of high combination, small sizes, removable, safe & reliable operation, easy maintenance and nice shape. This new electrical power distribution substation can be wide range used in the city public distribution, high building, residential quarter, mining, port, oil site, park, car station, air port, subways and high way.

Performance Features
1.lt has good heat insulation and ventilation measures. A double layers structure is adopted in the cabinet, and the heat insulationmaterial is also set in the interlayer, which effecively reduces the temperature rise caused by sunshine. 2.Safe and reliable operation. The high voltage side of the transformer substation selects RMU model XGN15- 12 and SRM-12, could alsoadopt other types of metal clad switchgear, complete Five-Preventions interlock. Each door frame has good waterproof structure.3.It is convenient to operate and maintain. Each compartment has automatic lighting device, transformer compartment has track andcart, convenient for transformer intallation, maintenance and replacement.4.The appearance is beautiful and durable. The cabinet shell is made of high performance marine zinc rich epoxy primer and epoxyanticorrosive mortar, which has good anticorrosive property, and the surface color can be configured arbitrarily with the environment.All electrical insallations are all galvanized, and it adopts a special anti blocking and anti rust universal lock.

Product Photo

The manufacturer can provide the foundation layout for their modular substation. The customer or user can design the foundation by themselves, but the layout need to be provided for manufacturer.The lightning conductors need to pre-lay in side or around of the foundation of the modular substation. The ground connection and lightning protection of the transformer can be jointly used as one grounding system. The grounding cables to the foundation platform should be not less than two lines and the grounding resistance should be guaranteed to be less than or equal to 4 Ohm.(R≤4Ω)For water proof, the gap between the modular substation and the foundation should be sealed with the cement concrete.
