Tailored to your needs, the rated voltage of our transformers can be customized to meet your exact specifications.
TSTY proudly presents the cutting-edge, fully sealed oil-immersed power transformer, meticulously engineered with
exceptional attributes such as significantly low loss, minimal noise, and outstanding efficiency. These features deliver remarkable energy-saving performance and substantially minimize environmental impact. Unlike standard oil-immersed transformers, our fully sealed variants eliminate the need for an oil conservator. The innovative design allows the oil volume to be automatically adjusted and compensated by the corrugated sheet's elasticity in the corrugated oil tank. The transformer remains air-isolated, thereby forestalling oil degradation and insulation aging, enhancing operational reliability, and ensuring maintenance-free performance during regular operation.

Product Details

12500kVA 11/0.4kv Aluminium Oil-Filled Transformer
Key Components:
This aluminum oil-filled transformer comprises vital components such as the Oil Tank, Conservator, Buchholz Relay, Breather Unit, Oil Indicator, Temperature Detector, Pressure Relief Device, Thermal Relay, Radiator, and Bushing.
1. The oil tank immerses the windings to ensure optimal cooling and insulation.
2. Fully compliant with IEC standards and proudly bearing CE/ISO certifications.
3. Designed for seamless contact and expansion during loading, allowing the oil temperature to rise and fall efficiently.
4. The Buchholz relay activates with a conservator tank to indicate issues like oil loss or improper oil flow between the tank and transformer.
5. The Breather Unit, filled with moisture-absorbing silica gel, changes color from blue to pink when it's saturated, signaling it can no longer absorb moisture.
6. The oil indicator precisely shows the oil level within the conservatory unit, ensuring optimal operations.
7. The temperature detector continuously monitors oil temperature, disconnecting the transformer from service if critical thresholds are met.
8. The pressure relief device mitigates excessive pressure within the transformer, preventing potential explosions.
9. The thermal relay serves as a crucial indicator for winding temperature.
10. Features a full galvanized coating to ensure rust-free longevity.
11. The bushing connects the transformer's internal windings to an external electrical network with precision and efficiency.
