Experience unparalleled efficiency with our range of Electrical Oil Transformers. Available in diverse capacities such as 50, 80, 100, 150, 160, and 200 kVA, and extending up to 1, 2, 2.5, 3, 4, and 5 MVA, these transformers are engineered for excellence. With voltage options of 11kV, 10kV, 0.4kV, and 400V, our 3-Phase Step Down Electric Power Oil Immersed Distribution Transformers ensure seamless power distribution and superior performance, making them an indispensable asset for your electrical infrastructure.
Tailored Voltage Options: The rated voltage is fully customizable to meet the specific requirements of our esteemed customers.
Revolutionary Design: The fully sealed oil-immersed power transformer, a pioneering development by TSTY, boasts the
exceptional advantage of low loss, minimal noise, and unparalleled efficiency. This innovative design achieves outstanding energy savings and significantly reduces environmental impact. Unlike conventional oil-immersed transformers, our fully sealed model eliminates the need for an oil conservator. The corrugated sheet of the oil tank automatically adjusts and compensates for oil volume changes, maintaining optimal operational conditions. The transformer is isolated from ambient air, effectively preventing oil degradation and insulation aging. This enhances operational reliability and minimizes maintenance requirements under normal conditions.
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 the crucial function of submerging the windings, ensuring efficient cooling and insulation.
2. Fully compliant with IEC standards and proudly certified with CE/ISO credentials.
3. Designed for seamless contact and expansion during loading, facilitating optimal temperature regulation of the oil.
4. The Buchholz relay is indispensable when a conservator tank is incorporated, as it detects critical faults such as low oil levels and improper oil flow between the tank and transformer.
5. The Breather Unit, containing silica gel, effectively absorbs moisture from the oil. The gel changes color from blue to pink when it is no longer capable of moisture absorption.
6. The oil indicator provides a clear, accurate reading of the oil level within the conservator unit.
7. The temperature detector meticulously monitors the oil temperature, ensuring the transformer is disconnected if temperatures rise beyond safe levels.
8. The pressure relief device is engineered to reduce internal pressure, preventing potential explosions within the transformer.
9. The thermal relay acts as a vital indicator, monitoring the winding temperature with precision.
10. Featuring a full galvanized coating, the transformer is highly resistant to rust and corrosion.
11. The bushing seamlessly connects the internal windings of the transformer to the external electrical network, ensuring reliable and efficient performance.
