Discover the exceptional 11/0.4kV and 33/0.4kV Copper Oil-Immersed Electric Power Transformer by TSTY ELECTRIC CO., LTD. This top-tier transformer is available in varying capacities: 50, 80, 100, 150, 160, and 200 kVA, as well as 1, 2, 2.5, 3, 4, and 5 MVA. Designed for optimal performance with voltages of 11kV, 10kV, 0.4kV, and 400V, this 3-phase step-down electric power oil-immersed distribution transformer ensures reliable and efficient energy distribution, making it the perfect choice for your power needs.
Our transformers offer customizable rated voltage to meet your specific requirements, ensuring versatility and adaptability for various applications.
Crafted with precision by TSTY, our fully sealed oil-immersed power transformers stand at the pinnacle of innovation and efficiency.
Boasting significant advantages such as low loss, minimal noise, and exceptional efficiency, our transformers deliver outstanding energy-saving performance and help in reducing environmental pollution. Unlike conventional oil-immersed transformers, our fully sealed models eliminate the need for an oil conservator. The oil volume adjusts automatically through the flexible corrugated oil tank, ensuring consistent performance. This isolation from air prevents oil degradation and insulation aging, thereby enhancing reliability and reducing the necessity for maintenance during normal operations.
Main Components:
This transformer boasts an array of essential and high-performance parts, including 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, ensuring optimal performance and longevity.
2. Compliant with IEC standards and proudly bearing CE/ISO certifications, our product guarantees quality and reliability.
3. Designed for easy connectivity and operational scalability, this unit ensures efficient temperature regulation by managing oil expansion and contraction.
4. The Buchholz relay is essential for conservator tank systems, alerting you to issues such as oil loss or improper oil flow between the tank and transformer.
5. The Breather Unit, equipped with silica gel, effectively absorbs moisture. Notably, the gel changes from blue to pink when moisture absorption capacity is reached.
6. The oil indicator reliably shows the oil level within the conservator unit, ensuring you can monitor and maintain optimal oil levels.
7. The temperature detector keeps a vigilant watch on the oil temperature, disconnecting the transformer from service if temperatures rise to critical levels.
8. To prevent transformer explosions, the pressure relief device efficiently reduces internal pressure.
9. The thermal relay acts as a precise indicator of winding temperature, providing crucial data for maintenance and safety.
10. Featuring a full galvanized coating, this transformer is completely rust-free, ensuring durability in various environments.
11. The bushing facilitates a seamless connection between the internal windings and the external electrical network, enhancing the transformer's efficiency and integration.
