Product Description


YB1-12/0.4 non-metallic shell preinstalled substation is a compact complete set of power distribution devices that preassemble the rated voltage 12kV high voltage distribution device , 12/0.4kV power transformer, low voltage

distribution device and energy metering device in a box . YB1-120.4 Non-metallic shell pre-installed substation is

mainly used for power supply and lighting in three-phase AC power system with rated frequency of 50Hz and rated voltage of 6-12/0.4kV. It is especially suitable for the transformation of distribution lines on both sides of the road in

the city network ,and can also be used in residential districts, streets, large construction sites, high-rise buildings, industrial and mining enterprises and temporary facilities. The product conforms to GB T17467 high voltage/low

voltage preinstalled substation, IEC601330 high voltage/low voltage preinstalled substation.

YB-12 series of products with beautiful shape, generous, excellent heat insulation performance and other

characteristics gradually favored by users. This series of preassembled substation adopts channel steel as base,

Angle steel as box frame (box body adopts sandwich color steel plate). The appearance of imported composite

board and aluminum-plastic board has excellent corrosion resistance, no rust, no fade, the overall structure is

simple, good rigidity, light weight, good heat insulation performance. The top cover is made of cold rolled plate

and glazed tile color steel plate. It has the properties of anti-explosion, anti-crack and anti-leakage. This series

of pre-installed substations are widely used in urban communities, commercial buildings and hotels, street

lighting projects, scenic spots and so on.
