The innovative fully sealed oil-immersed power transformer by TSTY ELECTRIC CO., LTD. boasts the
advantages of minimal loss, whisper-quiet operation, and superior efficiency , which not only delivers exceptional energy-saving benefits but also significantly reduces environmental pollution. In stark contrast to conventional oil-immersed transformers, our fully sealed model eliminates the need for an oil conservator, with the oil volume adjustments being seamlessly managed by the flexible corrugated oil tank's elasticity. This unique design ensures the transformer is hermetically sealed from the atmosphere, thereby preventing oil contamination and insulation degradation, enhancing operational reliability, and ensuring maintenance-free performance under regular operating conditions.

Product Details

High-Efficiency 12500kVA Copper Oil-Immersed Transformer for Power Supply
Main Components:
The primary components of the 12500kVA Copper Oil-Immersed Power Supply Transformer by TSTY ELECTRIC CO., LTD. include: 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 immerse the windings, ensuring optimal cooling and insulation.
2. This transformer complies with IEC standards and is certified with CE/ISO credentials, ensuring the highest quality and safety.
3. The Conservator enhances contact and expands during loading, facilitating the thermal regulation of the oil as its temperature fluctuates.
4. The Buchholz Relay is crucial when using a conservator tank. It detects errors such as low oil levels and improper oil flow between the tank and transformer, providing early warnings.
5. The Breather Unit contains silica gel that absorbs moisture from the oil, changing color from blue to pink when saturated and unable to absorb more moisture.
6. The Oil Indicator provides a clear view of the oil level within the conservator unit, ensuring proper monitoring.
7. The Temperature Detector constantly monitors the oil temperature, disconnecting the transformer from service if the temperature exceeds safe limits.
8. The Pressure Relief Device reduces internal pressure to prevent transformer explosions, ensuring operational safety.
9. The Thermal Relay serves as an indicator, showing the temperature of the windings to prevent overheating.
10. Featuring a full galvanized coating, this transformer is resistant to rust, ensuring longevity and durability.
11. The Bushing connects the internal windings of the transformer to the external electrical network seamlessly.
