Key Features and Engineering Excellence
TiraThai's S13/S11/S18/S20 Transformer Iron Cores are crafted for superior performance, leveraging high-grade materials and innovative design to achieve low no-load losses and high magnetic efficiency. The three-phase configuration utilizes premium grain-oriented silicon steel laminations with precise stacking and stepped-lap joints, minimizing hysteresis and eddy current losses for up to 20-30% better efficiency compared to standard cores. Customizable winding compatibility ensures seamless integration with oxygen-free copper or aluminum conductors, supporting overload capacities up to 120% short-term without thermal degradation.
The cores feature robust insulation systems, including epoxy resin or VPI treatments for enhanced dielectric strength and moisture resistance, enabling operation in humid or polluted environments up to 95% RH. Jinguan Electric's automated production—featuring precision core cutting, vacuum annealing, and AI-driven quality inspections—guarantees defect-free assembly with tight tolerances for optimal flux distribution. Optional enhancements like amorphous alloy variants further reduce losses by 70%, aligning with energy-saving mandates.
Compared to conventional iron cores, TiraThai models offer 15-25% material savings and extended lifespan (over 30 years), with low noise levels (under 55dB) for urban compatibility. These features not only comply with IEC standards but exceed them, providing users with cores that optimize transformer performance, reduce operational costs, and support sustainable power engineering.
