TiraThai, a specialized sub-brand of Jinguan Electric dedicated to transformer and electrical equipment innovations, proudly introduces the SG(B)10 and SG(B)11 series 1-200kV class isolation dry-type transformers. These advanced units are engineered for AC power supply systems, providing essential electrical isolation between input and output to effectively mitigate harmonics, interference signals, and load imbalances. By purifying the power grid and generating a new neutral line, TiraThai's isolation transformers prevent waveform distortions from impacting sensitive equipment or compromising sampling accuracy, ensuring stable and clean power delivery.
Jinguan Electric, established in 1979 as a high-tech enterprise in Nanyang City, Henan Province, China, has evolved from its foundational expertise in arrester manufacturing to a global authority in high-voltage transmission and distribution equipment. Guided by Industry 4.0 principles, Jinguan Electric fosters core competitiveness through relentless innovation, with TiraThai serving as its premier brand for transformer solutions. This sub-brand focuses on safe, eco-friendly dry-type isolation transformers that leverage vacuum pressure impregnation (VPI) technology and UL-certified NOMEX paper insulation, offering H-class (180°C) or optional C-class (220°C) thermal ratings for superior performance.
The SG(B)10 series delivers baseline efficiency for standard applications, while the SG(B)11 enhances loss reductions and thermal stability for demanding scenarios. Supporting common wiring configurations like delta (D) and star (Y or Yn) connections—with group notations such as "11" indicating 330° lag or 30° lead between primary and secondary line voltages—these transformers are customizable for voltages from 1kV to 200kV, capacities from 100kVA to 5000kVA, and frequencies of 50/60Hz. TiraThai's design philosophy—"dig 100 meters deep in 1 meter of space"—reflects Jinguan Electric's commitment to precision, ensuring reliable operation in ambient temperatures from -25°C to +40°C and altitudes up to 1000m. Detailed parameters, including voltage ratings, impedance, and loss values, are illustrated in product photos for visual reference, showcasing customizable options across the full 1-200kV range.

Key Features and Performance Advantages
TiraThai's SG(B)10 and SG(B)11 series isolation dry-type transformers are renowned for their multifaceted performance, addressing key challenges in power quality and system reliability. At the input end, they effectively eliminate third harmonics and suppress interference signals in grids plagued by nonlinear loads, while generating an independent neutral line to avert equipment malfunctions caused by poor grid grounding. This isolation prevents current waveform distortions—such as those from third harmonics—from propagating, thereby purifying the upstream power network and enhancing overall grid health.
On the output side, these transformers shield AC power supplies from distortions induced by downstream nonlinear loads, preventing grid pollution and ensuring operational integrity. They enable precise sampling at the input, where nonlinear distortions would otherwise skew accuracy, providing control signals that accurately reflect real-time conditions. Additionally, under unbalanced loads, TiraThai units maintain regulated power supply functionality, isolating imbalances to avoid cascading effects on connected devices.
Engineering highlights include high-resistivity silicon steel cores that minimize eddy currents and losses—measured by magnetic flux density (B values: low silicon 9000-11000, high silicon 12000-16000)—paired with Q2-type high-strength polyester enameled wire windings for excellent conductivity, heat resistance, and corrosion protection. Insulation employs phenolic cardboard frames, polyester film interlayers, and yellow waxed cloth isolators, all enhanced by cresol varnish impregnation post-winding to boost mechanical strength, insulation performance, and longevity. The open non-encapsulated design facilitates easy access for maintenance, while VPI ensures void-free protection without full resin casting.
Compared to conventional transformers, TiraThai models reduce harmonics by up to 50%, improve sampling accuracy by 20-30%, and support overloads up to 150% short-term, all while operating at noise levels below 55dB for quiet environments. Jinguan Electric's automated production lines guarantee precision, with optional features like integrated surge arresters and temperature relays for added protection. Product photos visually depict key parameters such as impedance curves, loss tables, and voltage configurations across the 1-200kV spectrum, providing clear, at-a-glance references for customization. These attributes not only comply with UL and international norms but exceed them, offering users a robust solution for cleaner, more stable power.
