Product Description
-
๐1. The floor area has been reduced by 80% โ 90%
Compared to conventional civil engineering substations that require separate buildings and spacious layouts, the YB-12 box-type transformer of the same capacity level requires only 1/10 to 1/5 of the floor area. This means that in urban centers, commercial complexes, or high-density residential areas where land resources are increasingly scarce, you can deploy a complete power distribution system in a space the size of a parking lot. This revolutionary improvement in space utilization efficiency directly translates into significant cost savings in land use and greater planning flexibility.

๐2. Wide Applicability and Adaptability
From high-rise building complexes in urban core areas, upscale residential communities, to emerging high-tech industrial parks; from rural and urban power grid renovation projects to small and medium-sized industrial and mining enterprises, even temporary construction sites and sports venues for short-term power usage, YB-12 can provide matching power supply solutions for all these scenarios. Its compact design makes it easy to be flexibly deployed in various complex environments.
-
๐ฐ3. Significant Optimization of the Entire Construction Cost
The prefabrication of the factory enables a reduction of over 70% in on-site construction volume. Users do not need to undertake complex substation design; they only need to provide a flat foundation, significantly simplifying the design process. The construction period can be shortened from the traditional 3โ6 months to 2โ4 weeks, significantly reducing labor, management, and financial costs. This "rapid deployment" capability is particularly suitable for commercial projects with tight schedules or emergency power supply requirements.

โ4. Modular Integration with Scientific Layout
This modular integration not only achieves seamless connection between devices, but also clearly separates the functional areas (high-voltage room, transformer room, low-voltage room) through a scientific layout. While ensuring the safe operating distance, it minimizes the overall volume to the greatest extent. Each unit has completed internal connections and tests before leaving the factory, truly realizing the advanced concept of "substation as a product".

Frequently Asked Questions
Q
What is the YB-12 box-type transformer and what is it used for?
The YB-12 box-type transformer is a compact, prefabricated power distribution unit that integrates a high-voltage cabinet, transformer, and low-voltage cabinet into a single modular enclosure. It is widely used in urban buildings, residential communities, industrial parks, construction sites, and rural grid renovation projects to provide reliable and efficient power distribution solutions.
Q
How much space does the YB-12 box-type transformer save compared to conventional substations?
The YB-12 reduces the required floor area by 80%โ90% compared to traditional civil engineering substations. It typically occupies only 1/10 to 1/5 of the space needed by a conventional substation of the same capacity, making it ideal for land-scarce urban environments.
Q
What is the rated capacity range of the YB-12 transformer?
The YB-12 transformer supports a rated capacity range of 100 KVA to 1,250 KVA, with a nominal voltage of 10/0.4 KV and a rated frequency of 50 Hz, making it suitable for a wide variety of small to medium-scale power distribution needs.
Q
How long does it take to install the YB-12 box-type transformer on-site?
Thanks to its factory-prefabricated and pre-tested design, the on-site installation period can be shortened from the traditional 3โ6 months to just 2โ4 weeks. Users only need to prepare a flat foundation, as all internal wiring and testing are completed before the unit leaves the factory.
Q
What is the shell protection grade of the YB-12 box-type transformer?
All three compartments of the YB-12 โ the high-voltage electrical cabinet, the transformer, and the low-voltage electrical cabinet โ are rated at IP23, providing adequate protection against solid objects and water ingress for standard outdoor and semi-outdoor installation environments.
Q
Is the YB-12 box-type transformer suitable for temporary or emergency power supply applications?
Yes. The YB-12's compact and modular design makes it highly suitable for temporary power needs such as construction sites, sports events, and emergency power supply scenarios. Its rapid deployment capability โ requiring minimal civil engineering work โ allows power infrastructure to be set up quickly wherever it is needed.
