The rated voltage of the Aluminium 33/0.4kV Electrical Power Transformer can be meticulously customized to meet the specific requirements of our esteemed customers.
The innovative, fully sealed oil-immersed power transformer developed by TSTY ELECTRIC CO., LTD. boasts an array of impressive features:
It offers the distinct advantages of exceptionally low loss, minimal noise, and outstanding efficiency, , delivering remarkable energy-saving benefits while significantly reducing pollution. Unlike conventional oil-immersed transformers, this fully sealed transformer eliminates the need for an oil conservator. The fluctuation in oil volume is seamlessly adjusted and compensated by the elasticity of the corrugated sheet within the corrugated oil tank. This design ensures complete isolation from air, thereby preventing and decelerating oil deterioration and insulation aging. As a result, it significantly enhances operational reliability and eliminates the need for maintenance during normal operation.
Main Components:
The primary parts of this aluminium 33/0.4kV electrical power transformer by TSTY ELECTRIC CO., LTD. include: Oil Tank, Conservator, Buchholz Relay, Breather Unit, Oil Indicator, Temperature Detector, Pressure Relief Device, Thermal Relay, Radiator, and Bushing.
1. The oil tank immerses the windings in oil, providing essential cooling and insulation.
2. Compliant with IEC standards and carrying CE/ISO certifications.
3. Allows easy contact expansion during loading, facilitating temperature regulation of the oil.
4. The Buchholz relay is crucial when utilizing a conservator tank. It detects issues such as oil loss or improper oil flow between the tank and transformer.
5. The Breather Unit contains silica gel to absorb moisture from the oil, changing color from blue to pink when saturated.
6. The oil indicator shows the oil level within the conservatory unit, ensuring optimal operation.
7. The temperature detector monitors oil temperature, disconnecting the transformer if temperatures exceed safe levels.
8. The pressure relief device mitigates internal pressure to prevent transformer explosions.
9. The thermal relay acts as a temperature indicator for the transformer windings.
10. Features a full galvanized coating to prevent rust.
11. The bushing connects the internal windings of the transformer to the external electrical network.
