The rated voltage can be customized to meet customers' specific requirements, ensuring maximum compatibility and flexibility.
The fully sealed oil-immersed power transformer, meticulously developed by TSTY, offers a distinctive
advantage of low loss, minimal noise, and outstanding high efficiency, which delivers exceptional energy-saving benefits while significantly reducing pollution. Unlike the conventional oil-immersed transformers, our fully sealed model eliminates the need for an oil conservator. Instead, it employs a corrugated oil tank with elastic corrugated sheets to autonomously adjust and compensate for oil volume changes. This advanced design isolates the transformer from the air, preventing oil deterioration and insulation aging, thereby enhancing operational reliability and minimizing maintenance during regular operation.

Product Details

12500kVA Aluminium Oil-Filled Power Transformer
Mainly Components:
The primary components of this transformer include: Oil Tank, Conservator, Buchholz Relay, Breather Unit, Oil Indicator, Temperature Detector, Pressure Relief Device, Thermal Relay, Radiator, and Bushing.
1. The oil tank submerges windings, ensuring optimal performance by being immersed in oil.
2. Complies with IEC standards and boasts CE/ISO certifications.
3. Facilitates easy contact and expansion during loading, enabling the oil temperature to fluctuate efficiently.
4. Buchholz relay is crucial when a conservator tank is employed. It detects faults such as oil loss or improper oil flow between the tank and transformer, ensuring reliable operation.
5. The Breather Unit, containing silica gel, absorbs moisture in the oil. It changes color from blue to pink when it can no longer absorb moisture, indicating it needs replacement.
6. The oil indicator shows the oil level within the conservator unit, aiding in effective monitoring.
7. The temperature detector keeps track of the oil's temperature. If it exceeds a certain threshold, the transformer is disconnected from service to prevent damage.
8. The pressure relief device mitigates internal pressure to prevent transformer explosions, ensuring safety.
9. The thermal relay serves as an indicator for winding temperature, providing critical data for safe operation.
10. Features full galvanized coating to prevent rust and ensure durability.
11. The bushing connects internal windings to the external electrical network, facilitating efficient power distribution.
