Advanced Features and Engineering Benefits
TiraThai's 110kV oil-immersed transformers are engineered for peak performance, incorporating premium materials and innovative designs that set new benchmarks in the high-voltage sector. The core utilizes high-grade, low-loss silicon steel laminations, stacked with stepped-lap joints to minimize magnetic flux leakage and hysteresis losses, achieving up to 25% better efficiency than legacy models. Windings are crafted from high-conductivity, oxygen-free copper, wound in continuous disc or helical configurations to enhance mechanical integrity and thermal distribution, ensuring the unit can endure short-circuit currents exceeding 40kA for 2 seconds without deformation.
The tank assembly features heavy-gauge welded steel with anti-corrosion coatings, equipped with expandable radiators for superior ONAN/ONAF cooling—natural oil natural air for base loads, with optional forced air for peak demands. This hybrid cooling extends overload capacity to 150% for extended periods, ideal for fluctuating grid conditions. Sealing is achieved through nitrile rubber gaskets and welded flanges, creating a hermetically sealed environment that prevents oil contamination and oxidation, thereby extending service life beyond 40 years with minimal interventions.
Noise reduction is a priority, with core clamping systems and vibration-dampening mounts limiting operational sound to under 65dB at full load, facilitating installations in urban or noise-regulated zones. Integrated accessories include on-load tap changers (OLTC) with ±8x1.25% steps for voltage regulation, Buchholz relays for gas detection, and pressure relief vents to mitigate internal faults. The oil preservation system employs a conservator with silica gel breathers, maintaining dielectric strength in varying climates. Jinguan Electric's state-of-the-art production facilities, featuring automated winding machines and vacuum oil-filling stations, ensure each transformer meets exacting tolerances, reducing field commissioning time by up to 30%.
These features not only comply with rigorous standards but also deliver tangible benefits: lower total ownership costs through reduced energy losses (typically 0.5-1% of throughput), enhanced grid stability, and simplified asset management via optional IoT-enabled monitoring for real-time diagnostics.
