Experience the reliability and excellence of TSTY ELECTRIC CO., LTD.'s 12500kVA Copper Oil-Immersed Electric Power Transformer.
The rated voltage is fully customizable to meet your specific requirements.
Discover the innovation of TSTY with its fully sealed oil-immersed power transformer, offering unparalleled performance.
Distinguished by its low loss, low noise, and exceptional efficiency, our transformer provides remarkable energy-saving benefits. This advanced design significantly reduces pollution. Unlike conventional oil-immersed transformers, our fully sealed model eliminates the need for an oil conservator. The corrugated oil tank's elasticity automatically adjusts and compensates for oil volume changes, ensuring the transformer remains isolated from air. This isolation prevents oil deterioration and insulation aging, enhancing operational reliability and minimizing maintenance.
Main 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 as a reservoir for immersing the windings, ensuring optimal cooling and insulation.
2. Fully compliant with IEC standards, and boasting CE/ISO certifications.
3. Designed for seamless contact and expansion during load variations, effectively managing oil temperature fluctuations.
4. The Buchholz relay operates with the conservator tank, detecting issues such as low oil levels and improper oil flow, ensuring rapid error identification.
5. The Breather Unit contains silica gel to absorb moisture from the oil. It signals saturation by changing from blue to pink.
6. The oil indicator accurately displays the oil level within the conservator unit.
7. The temperature detector continuously monitors oil temperature, triggering a disconnect if temperatures exceed safe thresholds.
8. The pressure relief device mitigates internal pressure, preventing potential explosions.
9. The thermal relay acts as a sensor for winding temperature, providing critical data for operation.
10. Features a full galvanized coating to ensure long-lasting protection against rust.
11. The bushing facilitates the connection between the internal windings and the external electrical network.
