Introducing the Oil-Immersed 33/0.4kV Electrical Transformer by TSTY ELECTRIC CO., LTD. Offering a range of capacities from 50 to 200 kVA and extending up to 5 MVA, this transformer operates at voltages of 11kV, 10kV, and 0.4kV (400V). Designed for 3-phase step-down electric power distribution, it ensures unparalleled efficiency and reliability. Whether you need 50, 80, 100, 150, 160, or 200 kVA, or even 1, 2, 2.5, 3, 4, or 5 MVA, our oil-immersed distribution transformer is the ultimate choice for seamless electrical power management.
The rated voltage can be fully customized to meet the specific needs and requirements of our customers.
The state-of-the-art fully sealed oil-immersed power transformer, meticulously developed by TSTY ELECTRIC CO., LTD., boasts exceptional features including
advantages such as low loss, minimal noise, and impressive high efficiency , resulting in significant energy savings and reduced environmental impact. Unlike conventional oil-immersed transformers, our fully sealed model eliminates the need for an oil conservator. The variation in oil volume is intelligently adjusted and compensated by the elasticity of the corrugated sheet within the corrugated oil tank. This innovative design ensures the transformer is hermetically sealed from the atmosphere, effectively preventing and decelerating oil degradation and insulation aging, thereby enhancing operational reliability and minimizing maintenance during regular operation.
Main Components:
The primary parts of this advanced transformer encompass the Oil Tank, Conservator, Buchholz Relay, Breather Unit, Oil Indicator, Temperature Detector, Pressure Relief Device, Thermal Relay, Radiator, and Bushing.
1. The oil tank is meticulously crafted to immerse the windings, ensuring optimal performance and cooling.
2. Adheres to IEC standards, supplemented with CE/ISO certifications for assured quality and reliability.
3. Engineered for excellent thermal management, it guarantees smooth loading with efficient heat dissipation.
4. The Buchholz relay is essential when utilizing a conservator tank, as it promptly indicates issues like oil loss or poor oil flow.
5. The Breather Unit, filled with silica gel, plays a critical role in moisture absorption. Its color change from blue to pink signals saturation.
6. The oil indicator provides a clear visual of the oil level within the conservator unit, ensuring proper maintenance.
7. The temperature detector vigilantly monitors oil temperature, disconnecting the transformer if temperatures reach critical levels.
8. The pressure relief device is pivotal in mitigating excess pressure, thus preventing potential transformer explosions.
9. The thermal relay functions as a precise indicator of winding temperature, ensuring safety and efficiency.
10. Fully galvanized coating ensures the structure remains rust-free, enhancing longevity.
11. Bushings provide seamless connectivity between the transformer's internal windings and the external electrical network.
