1Space Saving: 80–90% ReductionFloor Area Reduced by 80% – 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.

2Versatile ApplicationsWide 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.

3Cost Efficient: 70%+ Less On-Site WorkSignificant Optimization of 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 3–6 months to 2–4 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.

4Modular IntegrationSeamless Modular Design — "Substation as a Product"
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 is a compact, prefabricated box-type transformer substation that integrates a high-voltage electrical cabinet, transformer, and low-voltage electrical cabinet into a single modular unit. It is used to distribute electrical power in urban buildings, residential communities, industrial parks, construction sites, and other locations requiring reliable and space-efficient power supply solutions.
Q
How much floor space does the YB-12 box-type transformer require compared to a conventional substation?
The YB-12 requires only 1/10 to 1/5 of the floor area of a conventional civil engineering substation of the same capacity. This represents an 80–90% reduction in footprint, making it ideal for land-scarce urban environments, commercial complexes, and high-density residential areas.
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. The low-voltage side rated current ranges from 100 A to 2,500 A, making it suitable for a wide variety of power demand scenarios.
Q
How long does it take to install and commission the YB-12 box-type transformer?
Thanks to factory prefabrication, the YB-12 reduces on-site construction volume by over 70%. Installation typically takes only 2–4 weeks, compared to the 3–6 months required for traditional substation construction. Users only need to prepare a flat foundation — no complex substation design is required on-site.
Q
What is the shell protection grade of the YB-12, and is it suitable for outdoor installation?
All three main components of the YB-12 — the high-voltage cabinet, transformer, and low-voltage cabinet — carry an IP23 shell protection grade. This provides protection against solid objects and water spray at an angle, making the unit suitable for both indoor and semi-outdoor installation environments.
Q
What types of transformers are available in the YB-12, and what are the noise levels?
The YB-12 is available with either an oil-type or dry-type transformer. The oil transformer operates at a noise level of less than 55 dB, while the dry transformer operates at 65 dB or below. This makes both options suitable for noise-sensitive environments such as residential areas and commercial buildings.
