Designed for optimal performance, it operates efficiently at voltages of 11kV, 10kV, 0.4kV, and 400V. Our transformer is specifically engineered for 3-phase step-down electric power distribution, ensuring unparalleled reliability and energy efficiency. Experience the cutting-edge technology of our oil-immersed distribution transformers, ideal for diverse electrical applications.
The rated voltage can be customized to meet the specific requirements of our valued customers.
The innovative fully sealed oil-immersed power transformer engineered by TSTY ELECTRIC CO., LTD. offers unparalleled performance with
the remarkable advantages of low loss, low noise, and exceptional efficiency. This cutting-edge transformer not only ensures superior energy-saving benefits but also significantly reduces environmental impact. Unlike conventional oil-immersed transformers, our state-of-the-art fully sealed model eliminates the need for an oil conservator. The oil volume is automatically regulated and compensated by the corrugated oil tank's elastic corrugated sheet. This design isolates the transformer from air exposure, thereby preventing oil degradation and insulation aging, enhancing operational reliability, and ensuring maintenance-free performance under normal conditions.
Main Components:
The primary components of the Copper 3 Phase Electrical Oil-Immersed Transformer include the 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 crucial function by immersing the windings in oil, which is essential for cooling and insulation.
2. This transformer adheres to stringent IEC standards and is certified with CE and ISO credentials, ensuring top-notch quality and reliability.
3. It allows for easy contact and expansion during load variations, subsequently increasing and decreasing the oil temperature effectively.
4. The Buchholz relay, employed in systems with a conservator tank, signals issues such as oil loss or improper oil flow between the tank and transformer.
5. The Breather Unit contains silica gel, which absorbs moisture from the oil. The gel changes color from blue to pink when it becomes saturated and cannot absorb any more moisture.
6. The oil indicator displays the oil level within the conservator unit, ensuring proper monitoring.
7. The temperature detector monitors the oil temperature and will disconnect the transformer from service if the temperature exceeds safe levels.
8. The pressure relief device reduces internal pressure within the transformer, preventing potential explosions.
9. The thermal relay acts as an indicator for the winding temperature, ensuring optimal operation.
10. The transformer features a full galvanized coating, ensuring it remains rust-free and durable.
11. The bushing connects the internal windings of the transformer to the external electrical network, ensuring seamless power distribution.
