This high-capacity design makes TiraThai's 110kV Oil-Immersed Transformers a cornerstone for efficient, resilient power systems worldwide.
Key Features and Engineering Excellence
TiraThai's 110kV Oil-Immersed Transformers are engineered for excellence, featuring high insulation performance through premium mineral oil immersion, which provides superior dielectric strength and heat dissipation for continuous operation. The large capacity supports high-throughput energy transfer, while high efficiency minimizes losses, achieving >98% at full load. Strong heat dissipation via natural convection (ONAN) maintains thermal stability, even under overloads up to 120% short-term.
The robust construction includes grain-oriented silicon steel cores with stepped-lap joints for low hysteresis losses and oxygen-free copper windings for reduced resistance and enhanced short-circuit withstand (40kA/2s). Corrosion-resistant tanks and sealed designs ensure longevity in harsh environments, from humid coasts to dusty industrial sites. Jinguan Electric's automated production—featuring precision winding, vacuum oil-filling, and AI inspections—guarantees defect-free assembly, with optional on-load tap changers (OLTC) for voltage regulation.
Compared to air-cooled alternatives, TiraThai units offer 15-20% better thermal management and extended lifespan (over 30 years), with low noise (under 60dB) for urban compatibility. These features not only meet but exceed IEC 60076 and GB 1094 standards, providing users with a transformer that balances capacity, efficiency, and durability.
