12500kVA 33/11kv Oil Immersed Power Distribution Transformer: Experience unparalleled performance and robustness with our Oil Immersed Aluminium Power Distribution Transformer. Designed for optimal power management, this 12500kVA transformer operates at 33/11kv, ensuring superior energy distribution and stability for your electrical infrastructure.
The rated voltage can be customized to meet customers' specific requirements.
The fully sealed oil-immersed power transformer developed by TSTY ELECTRIC CO., LTD. offers
outstanding features such as low loss, low noise, and high efficiency, culminating in exceptional energy-saving performance and reduced pollution. Distinguished from ordinary oil-immersed transformers, this fully sealed variant eliminates the need for an oil conservator. The oil volume variations are automatically managed and compensated by the elasticity of the corrugated sheet within the corrugated oil tank. This design ensures the transformer remains isolated from the atmosphere, thereby preventing and decelerating oil deterioration and insulation aging. This significantly enhances operational reliability and negates the need for maintenance during standard operations.
Mainly Components:
The main components of this transformer include the Oil Tank, Conservator, Buchholz Relay, Breather Unit, Oil Indicator, Temperature Detector, Pressure Relief Device, Thermal Relay, Radiator, and Bushing.
1. The oil tank submerges the windings, providing essential cooling and insulation.
2. Meets IEC standards, certified with CE/ISO.
3. Designed for easy access and optimal heat dissipation, regulating oil temperature effectively.
4. The Buchholz relay, used with a conservator tank, detects faults such as oil loss and improper oil flow, ensuring safety and reliability.
5. The Breather Unit contains silica gel that absorbs moisture from the oil. Its color change from blue to pink indicates saturation and the need for replacement.
6. The oil indicator shows the oil level within the conservator unit, ensuring proper maintenance.
7. The temperature detector monitors oil temperature; if it exceeds a certain threshold, the transformer is disconnected to prevent damage.
8. The pressure relief device reduces internal pressure, preventing transformer explosions.
9. The thermal relay indicates winding temperature, providing critical information for operation.
10. Fully galvanized coating ensures rust-free performance.
11. The bushing connects the internal windings to the external electrical network, ensuring seamless power distribution.
