The rated voltage is fully customizable to meet the specific needs of our valued customers.
The pioneering fully sealed oil-immersed power transformer, developed by TSTY ELECTRIC CO., LTD., boasts
advantages of exceptionally low loss, minimal noise, and superior efficiency, rendering it a remarkable energy-saving solution that significantly cuts down on pollution. Unlike conventional oil-immersed transformers, our fully sealed design eliminates the need for an oil conservator. The fluctuation in oil volume is seamlessly adjusted and compensated by the elasticity of the corrugated sheet within the advanced corrugated oil tank. This innovative approach ensures the transformer remains isolated from air, thus preventing oil deterioration and insulation aging. The result is enhanced operational reliability and maintenance-free performance under normal operating conditions.

Product Details

12500kVA Aluminium Oil-Immersed Distribution Transformer
Mainly Components:
The main components of this state-of-the-art transformer include an Oil Tank, Conservator, Buchholz Relay, Breather Unit, Oil Indicator, Temperature Detector, Pressure Relief Device, Thermal Relay, Radiator, and Bushing.
1. The oil tank ensures optimal cooling and protection for the windings by completely immersing them in oil.
2. Adhering to stringent IEC standards, our transformer is certified with CE and ISO credentials.
3. The conservator allows for oil expansion and contraction, thereby regulating the oil temperature for enhanced performance.
4. The Buchholz relay is a critical safety component, alerting to issues like oil loss and improper oil flow between the tank and transformer.
5. Our Breather Unit is equipped with silica gel to efficiently absorb moisture. The gel changes from blue to pink, indicating its moisture saturation level.
6. The oil indicator provides precise readings of the oil level within the conservator unit.
7. The temperature detector vigilantly monitors oil temperature, disconnecting the transformer if unsafe levels are reached.
8. The pressure relief device mitigates the risk of explosions by reducing excess pressure within the transformer.
9. The thermal relay offers reliable temperature monitoring of the windings, ensuring optimal operation.
10. Fully galvanized coating ensures robust rust protection, extending the transformer's lifespan.
11. The bushing facilitates the connection of the transformer's internal windings to the exterior electrical network seamlessly.
