Introducing our state-of-the-art 12500kVA 33/11kV Oil-Immersed Power Distribution Transformer from TSTY ELECTRIC CO., LTD. Designed for unparalleled efficiency and reliability, this high-capacity transformer ensures optimal performance for all your power distribution needs. Engineered to perfection, it is the ideal solution for modern energy systems seeking robust and sustainable power management.
The rated voltage can be tailored precisely to meet customers’ specific requirements.
The fully sealed oil-immersed power transformer, meticulously developed by TSTY ELECTRIC CO., LTD., boasts an array of impressive features.
It stands out with its unparalleled low loss, whisper-quiet operation, and superior efficiency. This remarkable transformer not only promises excellent energy-saving capabilities and reduced pollution but also surpasses conventional oil-immersed transformers. By eliminating the oil conservator, it leverages the elasticity of the corrugated sheet in the oil tank to automatically adjust and compensate for changes in oil volume. This innovative design ensures the transformer remains isolated from air, effectively preventing oil deterioration and insulation aging. Consequently, it significantly enhances operational reliability and eliminates the need for maintenance during normal operation.
Main Components:
The main parts of this transformer include the Oil Tank, Conservator, Buchholz Relay, Breather Unit, Oil Indicator, Temperature Detector, Pressure Relief Device, Thermal Relay, Radiator, and Bushing.
1. The oil tank is designed to submerge the windings, ensuring optimal cooling and insulation.
2. Complies with IEC standards and holds CE/ISO certifications, ensuring top-notch quality and safety.
3. Effortlessly adapts to varying load conditions, regulating oil temperature efficiently.
4. The Buchholz relay operates with the conservator tank, signaling issues such as oil loss or improper oil flow, safeguarding the transformer's operation.
5. The Breather Unit, filled with silica gel, absorbs moisture from the oil, turning from blue to pink when saturated.
6. The oil indicator precisely shows the oil level within the conservatory unit.
7. The temperature detector continuously monitors the oil temperature, disconnecting the transformer if it exceeds safe levels.
8. The pressure relief device reduces internal pressure to prevent transformer explosions.
9. The thermal relay indicates the temperature of the windings, ensuring consistent performance.
10. Full galvanized coating ensures durability and prevents rust.
11. The bushing connects the internal windings of the transformer to the external electrical network efficiently.
