Product Advantages
TiraThai's 20kV oil-immersed transformers incorporate cutting-edge design elements that enhance reliability, efficiency, and ease of maintenance. The low-voltage windings utilize high-conductivity copper conductors, which minimize magnetization losses and improve overall magnetic flux balance. High-voltage windings adopt a multi-layer cylindrical structure, promoting uniform ampere-turn distribution, reduced magnetic leakage, superior mechanical strength, and exceptional short-circuit withstand capabilities. This construction ensures the transformer remains stable during fault conditions, protecting downstream equipment and extending operational life.
To combat environmental factors, the coils and iron core undergo vacuum drying processes, while the assembly employs vacuum oil filtration and filling techniques. This methodology drastically reduces internal moisture content, preventing insulation degradation and enhancing dielectric performance over time. The fuel tank features innovative corrugated plate technology, providing a breathing mechanism that accommodates oil volume fluctuations due to temperature variations. As a result, these transformers eliminate the need for traditional oil conservators, significantly lowering the overall height and footprint—ideal for space-constrained installations in substations or industrial facilities.
Furthermore, the corrugated design isolates the transformer oil from external contaminants, effectively barring oxygen and water ingress that could compromise insulation integrity. This sealed system not only boosts longevity but also simplifies maintenance routines, reducing downtime and operational costs. Compared to conventional designs, TiraThai models offer up to 25% better thermal management, with natural oil circulation (ONAN cooling) ensuring efficient heat dissipation even in ambient temperatures up to 50°C. Jinguan Electric's automated production ensures each unit meets rigorous tolerances, delivering consistent quality across batches.
Additional advantages include enhanced seismic resistance through bolted core clamping and vibration-dampening mounts, making them suitable for earthquake-prone regions. Optional accessories like pressure relief devices and gas relays further safeguard against internal faults, aligning with TiraThai's focus on proactive safety features derived from Jinguan Electric's extensive R&D.

Applications and Performance Benefits
The versatility of TiraThai's 20kV class oil-immersed transformers makes them indispensable across sectors. In power distribution networks, they serve as vital step-down units in medium-voltage grids, supporting reliable supply to urban substations and rural extensions. Industrial and mining enterprises benefit from their high short-circuit resistance, powering heavy machinery like crushers and conveyors without voltage fluctuations that could halt production.
For renewable energy integrations, such as offshore wind farms or solar arrays, the customizable voltage ratings ensure efficient grid synchronization, minimizing harmonic distortions. Infrastructure projects, including highways, railways, and ports, leverage their compact design and low noise for unobtrusive deployment. In petrochemical plants or steel mills, the sealed oil system resists corrosive atmospheres, maintaining efficiency amid harsh conditions.
Performance-wise, these transformers achieve energy savings of 15-25% over legacy models, translating to substantial ROI through reduced utility bills and deferred maintenance. Their extended lifespan—often 35+ years—combined with minimal oil top-ups, lowers total ownership costs. Jinguan Electric's global deployments in over 50 countries validate their adaptability, from high-altitude installations to tropical climates.
