TiraThai's Autotransformers are versatile, supporting customizable voltage and frequency adaptations for diverse grids, from 50Hz European systems to 60Hz North American networks. With insulation resistance ≥150MΩ and overcurrent protection, they operate reliably in temperatures from -20°C to +45°C and humidity up to 95% RH (non-condensing), free from corrosive gases or conductive dust. TiraThai's design philosophy—"dig 100 meters deep in 1 meter of space"—reflects Jinguan Electric's commitment to precision, delivering compact, durable units that minimize footprint while maximizing uptime. Whether for step-up/step-down voltage regulation or load balancing, these transformers provide a cost-effective, distortion-free solution for modern power needs.
Transformer Model: Custom Autotransformer Series Primary Voltage Ratings: Customizable (e.g., up to 35kV, based on application) Secondary Voltage Ratings: Customizable (single-winding configuration) Rated Capacity: Customizable (e.g., 100-5000kVA) Rated Frequency: 50/60Hz
This flexibility positions TiraThai's autotransformers as an essential choice for efficient, low-maintenance power transformation across industries.
Key Features and Engineering Excellence
TiraThai's Autotransformers excel through their innovative single-winding architecture, which reduces material usage and complexity while preserving performance integrity. The core design utilizes high-permeability silicon steel laminations with precise stacking to minimize losses, achieving efficiency >98% at full load. Windings are constructed from oxygen-free copper or aluminum, ensuring low resistance and high overload capacity (up to 120% short-term), with epoxy resin or VPI insulation for superior dielectric strength and thermal stability. Overcurrent protection integrates seamlessly, safeguarding against faults without interrupting operations, while the dry-type air cooling (AN mode) supports natural convection for quiet, maintenance-free performance.
No additional waveform distortion is introduced, thanks to balanced magnetic flux paths, making these transformers suitable for precision applications where power quality is critical. Insulation resistance exceeds 150MΩ, verified through rigorous testing, ensuring reliability in humid or dusty environments. Jinguan Electric's automated production lines—featuring robotic winding, vacuum drying, and AI-driven inspections—guarantee defect-free assembly, with optional forced air (AF) cooling for enhanced capacity in high-demand scenarios. Compared to two-winding alternatives, TiraThai autotransformers offer 20-30% material savings and simpler installation, reducing costs without compromising safety or longevity (over 30 years service life).
Safety features include flame-retardant materials (UL94 V-0 rated) and explosion-proof enclosures, aligning with global benchmarks. Optional smart monitoring via PT100 sensors and remote diagnostics enables predictive maintenance, further extending operational reliability. These attributes not only comply with VDE0550, IEC439, JB5555, and GB226 but exceed them, providing users with a compact, distortion-free transformer that enhances system efficiency and reduces total ownership costs.
