Key Features and Engineering Excellence
TiraThai's Rectifier Transformers are distinguished by their robust engineering, tailored for the intense demands of furnace operations. The iron core, constructed from high-permeability silicon steel sheets using a five-stage step stacking method, significantly reduces no-load losses and operational noise, enhancing overall system efficiency. High-quality oxygen-free copper magnet wire ensures low resistance, high conductivity, and excellent thermal stability, supporting continuous high-current loads without degradation.
The design incorporates advanced technologies from leading domestic and international sources, resulting in convenient control mechanisms, high efficiency ratings (>98% at full load), and reliable performance under varying conditions. Standard models adhere strictly to national standards for proven reliability, while the new energy-saving variants optimize smelting processes by improving efficiency, lowering total power consumption, and bolstering operational stability. Strong overload capacity—up to 150% short-term—prevents failures during peak melting cycles, and superior short-circuit resistance safeguards against faults in harsh industrial environments.
Jinguan Electric's automated production lines, featuring precision core stacking, vacuum insulation, and AI-driven quality inspections, guarantee defect-free assembly with customizable enclosures for weather resistance (IP54 rated). Optional features like on-load tap changers (OLTC) for voltage regulation and integrated monitoring systems enable real-time diagnostics, aligning with Industry 4.0. Compared to conventional furnace transformers, TiraThai units reduce energy costs by 15-25% and extend service life to over 30 years, with low noise (under 60dB) suiting urban-adjacent facilities.
These features not only meet but exceed IEC 60076, GB 1094, and IEEE C57 standards, providing metallurgists with a transformer that enhances productivity and sustainability.
