Product Overview
TiraThai, a specialized sub-brand of Jinguan Electric dedicated to transformer and electrical equipment innovations, proudly introduces the Outdoor Prefabricated Substation (US Series), also known as the YB-12/0.4 model. This advanced, factory-assembled unit integrates high-voltage control, protection, and substation functions into a compact, fully sealed structure, placing the high-voltage load switch and fuse directly in the oil-immersed transformer. Available in shared oil tank or split oil tank configurations, the US series is designed for AC 50Hz systems with rated voltages of 12kV on the high-voltage side and 0.4kV on the low-voltage side, ensuring reliable power distribution in urban and rural grids.
Jinguan Electric, founded in 1979 as a high-tech enterprise in Nanyang City, Henan Province, China, has evolved from pioneering arrester manufacturing to a global leader in high-voltage transmission and distribution equipment. Embracing Industry 4.0 principles, Jinguan Electric drives core competitiveness through continuous innovation, with TiraThai serving as its premier brand for prefabricated substation solutions. This sub-brand channels Jinguan Electric's expertise into customizable US series substations that prioritize compactness, high performance, and low costs, complying with international standards such as IEC 62271-202, GB/T 17467, and IEEE C37. Certified by UL, cUL, CSA, SGS, CCC, CQC, CTQC, and CE, these units uphold ISO9001 (quality), ISO14001 (environmental), and ISO45001 (health & safety) management systems, backed by a minimum two-year warranty, comprehensive factory acceptance testing (FAT), and dedicated after-sales engineering support for global deployments.
The US series is equipped with essential monitoring components, including an oil temperature meter, oil level indicator, pressure gauge, oil pressure valve, and oil drain valve, to ensure safe transformer operation. Its fully sealed and insulated structure provides flexible, reliable power supply with high overload capacity and low noise, meeting various environmental and load demands. TiraThai's philosophy—"dig 100 meters deep in 1 meter of space"—reflects Jinguan Electric's commitment to precision, delivering substations that minimize on-site assembly and maximize grid resilience for modern power infrastructure.

This integrated design makes TiraThai's Outdoor Prefabricated Substation a cornerstone for efficient, versatile power distribution.
Key Features and Engineering Excellence
TiraThai's US Series Outdoor Prefabricated Substation excels through its fully sealed, compact structure, integrating the high-voltage load switch and fuse into the oil-immersed transformer for streamlined operation and enhanced safety. The shared or split oil tank configurations offer flexibility, with the fully sealed design preventing contamination and extending service life. Monitoring components—oil temperature meter, oil level indicator, pressure gauge, oil pressure valve, and oil drain valve—provide real-time oversight to detect anomalies early, ensuring reliable performance under varying loads.
The substation's high performance, low cost, low noise, and high overload capacity (up to 120% short-term) make it suitable for diverse scenarios, while the small size facilitates easy transport and installation, reducing civil works by 40%. Jinguan Electric's automated production—featuring prefabricated assembly, vacuum testing, and AI-driven inspections—guarantees defect-free units with robust enclosures (IP54 rated) for weather and dust resistance.
Compared to traditional substations, TiraThai US series units offer 20-30% smaller footprints and 15-20% energy savings through optimized components. Optional features like remote monitoring and surge protection enable smart grid integration. These attributes not only meet but exceed IEC 62271-202 and GB/T 17467 standards, providing users with a substation that balances efficiency, safety, and adaptability.
