It is suitable for new residential areas, green belts, parks, stations, hotels, construction sites, airports and other places.

Ybw-12 series combined box type substation (American box type substation) is suitable for 10kV ring network power supply, dual power supply or terminal power supply system, as a power transformation, metering, compensation control and protection device.

This product meets the following standards: GB / t17467-1998 "high voltage and low voltage prefabricated substation", DL / t537-93 "technical conditions for ordering 6-35kV box type substation"

Model meaning

Product features

⦿ fully insulated, fully sealed, less maintenance free, reliable to ensure personal safety;

⦿ compact structure, volume is only 1 / 3-1 / 5 of the European transformer with the same capacity and low height;

⦿ separate box structure can be adopted to avoid oil pollution in transformer tank;

⦿ the high voltage side adopts double fuse full range protection, which greatly reduces the cost

⦿ it can be used for both ring network and terminal. The cable head can be plugged in and out in case of 200A load current;

⦿ the box adopts honeycomb double sandwich composite board, which has the function of temperature isolation and heat dissipation;

⦿ the low voltage side is equipped with an electronic open phase protector, which can quickly turn off the main incoming switch when abnormal voltage occurs in the system;

⦿ the oil immersed load switch or SF6 load switch on the high voltage side can be upgraded electrically, laying a foundation for the realization of distribution network automation.

⦿ adopt oil immersed S9 or S11 series transformer with better performance.

Normal use environment

⦿ altitude not more than 1000m;

⦿ ambient temperature: - 35 ℃ ~ + 40 ℃;

⦿ relative humidity: the daily average value is not more than 95%, and the monthly average value is not more than 90%;

⦿ installation site: no fire, explosion hazard, chemical corrosive gas and well ventilated place, and the ground inclination angle shall not be greater than 3 °.
