Experience the unparalleled performance of the 12500kVA 33/11kV Oil-Immersed Power Distribution Transformer from TSTY ELECTRIC CO., LTD. Engineered for excellence, this high-capacity transformer is designed to meet the demanding energy requirements of modern industries. Its superior oil-filled insulation ensures reliable and efficient power distribution, making it the perfect choice for both urban and rural applications. Trust in a powerhouse of innovation and reliability with TSTY ELECTRIC CO., LTD.
The rated voltage can be tailored to meet the unique requirements of our valued customers.
The fully sealed, oil-immersed power transformer engineered by TSTY ELECTRIC CO., LTD. stands out with
its remarkable benefits: low loss, minimal noise, and outstanding efficiency, which deliver substantial energy savings and reduce environmental impact. Unlike standard oil-immersed transformers, our fully sealed transformer eliminates the need for an oil conservator. The oil volume is dynamically adjusted and compensated via the flexibility of the corrugated oil tank's sheet. This design ensures the transformer is completely isolated from air, preventing oil degradation and insulation aging, thereby enhancing operational reliability and eliminating the need for maintenance under normal operating conditions.
Main Components:
The primary components of the 33/11kV High Capacity Oil-Filled Transformer include an Oil Tank, Conservator, Buchholz Relay, Breather Unit, Oil Indicator, Temperature Detector, Pressure Relief Device, Thermal Relay, Radiators, and Bushings.
1. The oil tank immerses the windings in oil, ensuring optimal cooling and insulation.
2. Compliant with IEC standards and certified with CE/ISO certificates.
3. Easily accessible and able to expand under load, allowing the oil temperature to rise and fall as needed.
4. The Buchholz relay activates in the event of a conservator tank error, such as oil loss or improper oil flow between the tank and transformer.
5. The Breather Unit uses silica gel to absorb moisture in 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 proper maintenance.
7. The temperature detector monitors the oil temperature, disconnecting the transformer from service if the oil overheats.
8. The pressure relief device reduces internal pressure to prevent transformer explosions.
9. The thermal relay indicates the winding temperature, providing critical safety information.
10. Fully galvanized coating ensures no rust, extending the transformer's lifespan.
11. Bushings connect the transformer’s internal windings to the external electrical network, ensuring a seamless electrical flow.
