Empowered with an exceptional design, the 11/0.4kV Aluminium Oil-Filled Distribution Transformer by TSTY ELECTRIC CO., LTD. comes in a range of power ratings: 50, 80, 100, 150, 160, 200 kVA and 1, 2, 2.5, 3, 4, 5 MVA. This robust transformer operates at 11kV, 10kV primary voltage, stepping down to 0.4kV or 400V. With a reliable 3-phase mechanism, this oil-immersed distribution transformer ensures efficient and seamless electric power distribution.
The rated voltage of our 11/0.4kV Aluminium Oil-Filled Distribution Transformer can be tailored precisely to meet your specific requirements.
Innovatively engineered by TSTY, our fully sealed oil-immersed power transformer showcases the
distinct advantages of minimal loss, reduced noise, and exceptional efficiency, delivering remarkable energy-saving benefits while minimizing environmental impact. Unlike conventional oil-immersed transformers, our fully sealed variant eliminates the need for an oil conservator. The oil volume adjustments are seamlessly managed through the elasticity of the corrugated oil tank sheet. This design isolates the transformer from air, thus mitigating oil degradation and insulation aging. This enhances operational reliability and ensures maintenance-free performance under normal conditions.
Main Components:
The primary components of this 11/0.4kV Aluminium Oil-Filled Distribution Transformer include the following: Oil Tank, Conservator, Buchholz Relay, Breather Unit, Oil Indicator, Temperature Detector, Pressure Relief Device, Thermal Relay, Radiator, and Bushing.
1. The oil tank is designed to immerse the windings, ensuring efficient cooling and insulation.
2. Compliant with IEC standards, and certified with CE/ISO for quality and safety.
3. Easily accessible for contact and load management, allowing the oil temperature to rise and fall efficiently.
4. The Buchholz relay operates with the conservator tank, detecting issues such as oil loss and improper oil flow between the tank and the transformer.
5. The Breather Unit contains silica gel that absorbs moisture from the oil, changing from blue to pink when saturated and unable to absorb more moisture.
6. The oil indicator shows the oil level within the conservator unit, ensuring optimal operation.
7. The temperature detector continuously monitors the oil temperature, disconnecting the transformer from service if the temperature exceeds safe levels.
8. The pressure relief device mitigates internal pressure to prevent explosions, enhancing safety.
9. The thermal relay acts as a temperature indicator for the windings, providing crucial data for operational safety.
10. Fully galvanized coating prevents rust, ensuring long-term durability and reliability.
11. The bushing connects the internal windings of the transformer to the external electrical network, facilitating efficient power transfer.
