Product Overview
YB-12/0.4-1250 Type High/Low Voltage Prefabricated Substation (commonly known as "Box-type Substation" or "European-style Box Transformer") is a complete set of power distribution equipment that integrates high-voltage switchgear, distribution transformer, and low-voltage distribution devices. It is suitable for power conversion and distribution between 10kV (or 12kV) high-voltage side and 0.4kV low-voltage side, widely used in urban power grids, industrial parks, residential communities, and new energy (photovoltaic/wind power) fields.
Key Features
- Integrated design: High-voltage room, transformer room, and low-voltage room modular combination with compact structure and small footprint
- Safe and reliable: Fully enclosed metal shell, protection level reaching IP33~IP54 (higher optional)
- Flexible configuration: Can choose outdoor or indoor type, ring network or terminal power supply scheme
- Intelligent management: Optional intelligent monitoring system for real-time monitoring of voltage, current, temperature and other parameters
Product Advantages
- Rapid installation: Factory debugging completed, only foundation construction and cable connection needed on site
- Energy saving and environmental protection: Using S20/SCB14 high-efficiency transformers, meeting GB20052-2024 energy efficiency standards
- Easy maintenance: Modular design, independent unit inspection, reduced O&M costs
Applications
- Municipal Power Grid: Power distribution renovation for urban roads, residential areas, and commercial centers
- Industrial Power: Large capacity load power supply for factories, mines, and oil fields
- New Energy Field: Photovoltaic power stations, wind farm boost grid connection
- Temporary Power: Short-term power needs for construction sites, exhibitions, etc.
