YB□-12/0.4 [F.R] /T-□(European) type outdoor pre-installed substation
YB series pre-installed substation is the combination of high-voltage electrical equipment, transformers, low-voltage electrical equipment into a compact complete set of power distribution devices, used in urban high-rise buildings, urban and rural buildings, residential communities, high-tech development zones, small and medium-sized factories, mining oil fields and temporary construction of electricity and other places, for the distribution system to accept and distribute electric energy.
The substation adopts a European-style enclosed structure with independent compartments for HV, transformer, and LV sections, ensuring safe operation and maintenance in compliance with IEC 62271-202 standards.

AMBIENT CONDITION
Altitude not exceeding 2500m.
Ambient temperature: -25°C to +40°C.
Relative humidity: Daily average not exceeding 95%, monthly average not exceeding 90%.
Installation location: No fire, explosion hazards, conductive dust, chemically corrosive gases, and severe vibrations. If conditions
exceed the above, the user can negotiate with the company.
HIGH VOLTAGE SIDE
The high-voltage side of the smart integrated substation generally uses load switch-fuse combination electrical protection. After the fuse of one phase is blown, the three phases are interlocked and tripped. Load switches are available in various types such as pressure type, vacuum, and sulfur hexafluoride, with optional electric operating mechanisms for automation upgrades. The fuse is a high-voltage current-limiting fuse with an impactor, reliable action, and large breaking capacity.
Key Features
- Compact Integral Design: Integrates HV, transformer, and LV sections into a single enclosure, reducing footprint by up to 60% compared to traditional brick-built substations
- Flexible Transformer Options: Compatible with both oil-immersed (S11/S13 series, low-loss) and dry-type (SCB series, cast resin) transformers to suit different installation requirements
- Interchangeable Components: Standardized design allows easy replacement and upgrade of individual sections without major reconstruction
- Anti-Corrosion Protection: Heavy-duty steel enclosure with anti-corrosion, anti-UV coating, and weatherproof seals ensures 20+ years of outdoor service life in harsh environments
- Full Interlocking System: Mechanical interlocks prevent incorrect operations, ensuring safe HV-to-LV sequential switching
- Low Maintenance: Factory-assembled and tested, requiring only periodic inspection and basic maintenance
APPLICATIONS
Widely used in urban power grid reconstruction, residential communities, high-rise buildings, industrial and mining enterprises, hotels, shopping malls, airports, railways, oil fields, docks, highways, and temporary electric facilities both indoors and outdoors.
