TiraThai, a specialized sub-brand of Jinguan Electric focused on transformer and electrical equipment innovations, proudly introduces the SCB Series 10kV Epoxy Resin Dry-Type Transformers. These high-performance units serve as an ideal replacement for oil-immersed distribution transformers, offering superior safety, efficiency, and reliability for penetrating load centers. Engineered for urban power grids, high-rise buildings, business centers, hospitals, hotels, tunnels, subways, underground power stations, laboratories, stations, docks, airports, and combined substations, the SCB series excels in environments requiring compact, fire-safe solutions without the risks of oil leaks or spills.
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 dry-type transformer solutions. This sub-brand leverages Jinguan Electric's rigorous quality control and advanced manufacturing to deliver SCB transformers that comply with international standards, including IEC 60076, GB/T 10228-1997, and IEEE C57.12.01. Certified by UL, CUL, CCC, CQC, CTQC, CE, and SGS, these units uphold ISO9001 (quality), ISO14001 (environmental), and ISO45001 (health & safety) management systems, ensuring exceptional performance and sustainability.
The SCB series, encompassing models like SCB10, SCB11, SCB12, and SCB13, achieves progressive efficiency: SCB10 reduces no-load losses by 10% below GB/T10228 Group I, while higher variants push to 30% with optimized casting. Supporting primary voltages up to 10kV and capacities from 30kVA to 2500kVA, they operate at 50/60Hz with vector groups Dyn11 or Yyn0. TiraThai's philosophy—"dig 100 meters deep in 1 meter of space"—reflects Jinguan Electric's commitment to precision, delivering transformers that minimize environmental impact and maximize grid resilience for critical infrastructure.
Transformer Model: SCB Series (SCB10/SCB11/SCB12/SCB13) Primary Voltage Ratings: Up to 10kV (Customizable) Secondary Voltage Ratings: 0.4kV (Customizable) Rated Capacity: 30-2500kVA (Customizable) Rated Frequency: 50/60Hz
This versatility makes TiraThai's 10kV SCB Series Epoxy Resin Dry-Type Transformers a cornerstone for safe, efficient urban and industrial power.
Key Features and Engineering Excellence
TiraThai's SCB Series Epoxy Resin Dry-Type Transformers are renowned for their vacuum casting process, where the low-voltage coil is wound with foil and cured into an integral structure through end sealing, while the high-voltage coil is cast with epoxy resin in a vacuum state, forming a solid cylindrical whole after curing. This design provides high mechanical strength, low partial discharge, and superior reliability, with resistance to short circuits and high lightning impact levels. The thin inner and outer resin layers enhance heat dissipation, ensuring optimal thermal performance.
Cooling methods include air natural cooling (AN) for standard operation, with optional air cooling systems (AF) to boost short-term overload capacity and ensure safe running under peak loads. The transformers boast low losses for significant power savings, economical operation, and maintenance-free design, with small size and light weight reducing footprint and installation costs—no need for oil tank fire suppression or backup power. Enclosure protection reaches IP20 or IP23, using stainless steel or aluminum alloy shells to prevent solid foreign objects over 12.5mm from entering and water droplets at 60° angles for outdoor suitability.
The temperature control system, comprising a temperature controller and PTC element at the low-voltage winding's hottest spot, enables precise temperature measurement and control. If windings overheat due to overload or faults, it triggers alarms and auto-trips at safe thresholds. For AF cooling, the controller manages fan input based on winding temperature, with a display system showing hotspot temperatures for real-time oversight. Jinguan Electric's automated manufacturing—featuring robotic winding, vacuum casting, and AI inspections—guarantees defect-free assembly. Compared to oil-immersed models, TiraThai SCB units reduce fire risks and maintenance by 50%, with 15-20% energy savings.
These features not only meet but surpass GB/T10228-1997 and IEC 60076 standards, positioning TiraThai as a leader in resilient, green power transformation.
