Experience the pinnacle of power distribution with TSTY's state-of-the-art, fully sealed oil-immersed power transformer.
Designed to deliver unparalleled low loss, minimal noise, and exceptional high efficiency, this innovative transformer not only achieves remarkable energy-saving results but also significantly reduces pollution. Unlike conventional oil-immersed transformers, our fully sealed model eliminates the need for an oil conservator. The oil volume adjusts automatically through the flexible corrugated sheet within the oil tank, providing superior air isolation. This design prevents oil deterioration and insulation aging, ensuring enhanced operational reliability and maintenance-free performance under normal conditions.

Product Details

Efficient Power Distribution Oil Immersed Transformer
Mainly Components:
The primary components of this state-of-the-art 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 serves a critical function by immersing the windings in oil, ensuring optimal cooling and insulation.
2. Designed to fully comply with IEC standards, boasting CE and ISO certifications for unparalleled reliability.
3. Engineered for seamless operation, the oil can expand and contract during load variations, effectively managing temperature changes.
4. The Buchholz relay, essential in systems with a conservator tank, detects anomalies such as low oil levels and improper oil flow between the tank and transformer.
5. Our Breather Unit contains silica gel that efficiently absorbs moisture from the oil. The gel changes from blue to pink to indicate saturation and the need for replacement.
6. The oil indicator provides an accurate readout of the oil level within the conservatory unit, ensuring proper maintenance.
7. The temperature detector continuously monitors oil temperature, and disconnects the transformer from the service if the temperature exceeds safe levels.
8. Our pressure relief device is crucial for reducing internal pressure, thereby preventing potential transformer explosions.
9. The thermal relay acts as a precise indicator of the windings' temperature, ensuring the transformer operates within safe limits.
10. Features full galvanization to prevent rust, ensuring long-term durability and performance.
11. Bushings facilitate the connection of the transformer's internal windings to external electrical networks, ensuring robust and reliable connectivity.
