Engineered to perfection, these transformers ensure optimal performance and reliability for all your power distribution needs.
The rated voltage can be tailored precisely to meet customers' exact specifications, ensuring unmatched compatibility and performance.
The state-of-the-art, fully sealed oil-immersed power transformer engineered by TSTY ELECTRIC CO., LTD. embodies excellence with
remarkable features such as low loss, minimal noise, and superior efficiency , delivering outstanding energy-saving benefits while significantly curbing pollution. Unlike conventional oil-immersed transformers, our advanced fully sealed design eliminates the need for an oil conservator. The system automatically adjusts and compensates for oil volume changes using the flexible corrugated oil tank. This innovative isolation from air effectively prevents oil degradation and insulation aging, elevating operational reliability and enabling maintenance-free operation under normal conditions.
Main Components:
The primary components of this transformer are: 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 efficient cooling and insulation.
2. Fully compliant with IEC standards and certified with CE/ISO.
3. Ensures easy connectivity and expansion during load fluctuations, allowing the oil temperature to rise and fall accordingly.
4. The Buchholz relay operates with a conservator tank, detecting issues like oil loss and improper oil flow between the tank and transformer.
5. The Breather Unit contains silica gel that absorbs moisture from the oil. It changes color from blue to pink when saturated and needs replacement.
6. The oil indicator shows the oil level within the conservator unit.
7. The temperature detector monitors oil temperature, disconnecting the transformer from service if it exceeds safe levels.
8. The pressure relief device releases excess pressure within the transformer to prevent explosions.
9. The thermal relay indicates the winding temperature, ensuring safe operation.
10. Features a full galvanized coating to prevent rust.
11. The bushing connects internal windings to the external electrical network, ensuring seamless integration.
