Overview
Product Information
Product Description:
YB27 series Prefabricated transformer substation is our company made Pad mounted transformer. It is an important equipment in the
cable distribution network. It is a kind of complete prefabricated product with high voltage control, protection, power
transformation and power distribution, It is widely used in 7.2~40.5kV electric power distribution system, widely used in the
urban and rural distribution network . This equipment complies with the requirements of standard IEC61330 etc.
The product equipped the HV load switch and HV fuse in transformer oil .It has common box or separate box with transformer body.
Oil tank is enclosed sealed with oil temperature gauge, oil level indicator, pressure gauge , pressure relief valve ,drain oil
valve etc to monitor the transformer working conditions.The product has loop feed ,radial feed & power supply type.In order to
make this product more suitable for the actual requirements of power grid , we have also introduced plug-in type dry type fuse
which fusing do not affect the transformer oil. According to the complexity of low voltage outgoing requirements,YB27 enclosure
has standard type, intensive and comprehensive type to make user choice more economic & flexible.
■ Service conditions
1.Ambient air temperature: -30℃~+50℃
2.Altitude : Maximum installation altitude: 2500m
3.Outdoor wind speed is not more than 34m/s;
4.Relative humidity: daily average value ≤95%, the monthly average value ≤ 90%;
5.Inclination of installation site : not more than 3 °;
6.Installation site: no explosion danger, serious pollution, chemical corrosion , severe vibration
■ Products advantage:
1.Compact structure, small volume, is only about the 1/3 – 1/5 of the same capacity european type substation, which greatly reduce
the occupation area
2.Fully sealed and fully insulated structure, no need insulation distance , .
3.The wiring connection of high voltage can be used in loop feed and radial feed. Power supply method is flexible and reliable.
4.Excellent performance; low consumption, low noise, low temperature –rising, high overload, anti short-circuit, high impact
resistance, reliable protection of personal safety
5.Meet all kinds of low voltage outgoing requirements .
6.Cable head has 200A elbow plug & 630A “T” shape fixed type. All insulated Zinc Oxide lightning arrester can be configured. 200A
cable head can be plugged in with load, also can be acted as isolation switch.
