Introducing the 12500kVA 33/11kV Oil Immersed Power Distribution Transformer by TSTY ELECTRIC CO., LTD. This high-performance transformer is expertly designed to efficiently manage and distribute electrical power, ensuring seamless and reliable energy transfer. With a robust oil-filled system, it guarantees superior insulation and cooling, making it the perfect solution for all your power distribution needs.
The rated voltage can be precisely tailored to meet the unique specifications of our valued customers.
The cutting-edge, fully sealed oil-immersed power transformer engineered by TSTY ELECTRIC CO., LTD. boasts an array of exceptional features.
It offers remarkable advantages such as ultra-low loss, whisper-quiet operation, and unparalleled efficiency, which collectively deliver outstanding energy savings and significantly curtail environmental pollution. Unlike traditional oil-immersed transformers, our innovative fully sealed design eliminates the need for an oil conservator. The transformer cleverly adjusts and compensates for oil volume fluctuations through the corrugated sheet's elasticity within the corrugated oil tank. This isolation from air helps to prevent and decelerate oil deterioration and insulation aging, thereby enhancing operational reliability and eliminating the need for maintenance under normal conditions.
Key Components:
Our state-of-the-art 33/11kV Oil-Filled Electrical Supply Transformer boasts several crucial components 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 is ingeniously designed to submerge the windings, providing optimal insulation and cooling.
2. Adheres to rigorous IEC standards and comes with CE/ISO certifications, ensuring reliability and safety.
3. Facilitates seamless contact and expansion under load, efficiently regulating the oil temperature.
4. The Buchholz relay operates within the conservator tank to detect faults such as oil loss or improper oil flow, providing early warnings to prevent damage.
5. The Breather Unit, filled with moisture-absorbing silica gel, shifts color from blue to pink when saturated, indicating the need for maintenance.
6. The oil indicator grants a clear view of oil levels within the conservator unit, ensuring proper maintenance.
7. An advanced temperature detector keeps a vigilant watch on oil temperatures, disconnecting the transformer if overheating is detected.
8. The pressure relief device mitigates internal pressure, preventing potential transformer explosions.
9. The thermal relay serves as a crucial temperature indicator for the windings, ensuring operational safety.
10. Fully galvanized coating guarantees complete rust resistance, extending the transformer's longevity.
11. Bushings provide a reliable connection between the internal windings and the external electrical network, ensuring seamless power distribution.
