products description
1.The floor area has been 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.
2. 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.
3. 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 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.
4.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".

FAQ
Find answers to common questions about 35kV wind power prefabricated substations, including transformer capacity, corrosion protection, harsh-environment operation, system configuration and project customization.
REQUEST TECHNICAL REVIEW
What is this 35kV prefabricated substation mainly used for?
This prefabricated substation is designed for **35kV power systems**, especially for wind farms, renewable energy projects, industrial power systems, and outdoor substations. It can integrate transformer, medium-voltage switchgear, low-voltage equipment, protection, control, and auxiliary systems into a compact prefabricated enclosure.
Is this substation suitable for wind power projects?
Yes. The substation can be configured for wind power applications according to the project electrical design. For wind farm projects, the transformer rating, voltage ratio, switchgear configuration, protection system, cable interfaces, communication requirements, and environmental protection design can be customized according to the project single-line diagram.
What transformer capacity can be installed in the 35kV substation?
The transformer capacity is selected according to the wind turbine capacity, system design, collection network, load conditions, and project requirements. Different kVA or MVA ratings can be designed. Please provide the required transformer capacity, voltage ratio, and project single-line diagram for technical confirmation.
What does the corrosion-resistant design include?
For harsh outdoor environments, the enclosure and exposed components can be designed with enhanced anti-corrosion protection. Depending on the project requirements, the corrosion-resistant design may include: * Enhanced surface coating * Corrosion-resistant enclosure materials * Protected fasteners and external metal parts * Improved sealing * Moisture-resistant design * Salt-spray-resistant treatment where required The final anti-corrosion level should be confirmed according to the actual site conditions and project specification.
Can this substation be used in coastal or high-humidity environments?
Yes, but the actual environmental conditions must be confirmed before design. For coastal, high-humidity, high-salinity, or heavily polluted environments, we recommend providing the site temperature, humidity, altitude, pollution level, salt-spray conditions, and corrosion requirements so that the enclosure, coating, sealing, ventilation, and electrical components can be properly selected.
What equipment can be integrated inside the substation?
A 35kV prefabricated substation can be configured with: * 35kV medium-voltage switchgear * Power transformer * Low-voltage distribution equipment * Protection and control devices * Metering equipment * Auxiliary power supply * Temperature monitoring * Communication equipment * Cable connection systems The final configuration depends on the project single-line diagram and technical specification.
How is heat dissipation managed inside the substation?
Heat dissipation is designed according to transformer losses, internal equipment heat generation, enclosure dimensions, ambient temperature, and operating load. Natural ventilation, optimized ventilation openings, forced ventilation, or other cooling measures can be selected according to project conditions to keep equipment operating within the required temperature limits.
