The rated voltage can be customized to meet each customer’s unique requirements.
The fully sealed oil-immersed power transformer by TSTY ELECTRIC CO., LTD. boasts
the advantages of low loss, minimal noise, and superior efficiency, which combine to deliver excellent energy-saving performance and reduced pollution. Unlike ordinary oil-immersed transformers, our fully sealed design eliminates the oil conservator. The oil volume adjusts automatically through the elasticity of the corrugated sheet in the tank, isolating the transformer from air exposure, thus preventing oil deterioration and insulation aging. This innovation enhances operational reliability and eliminates the need for maintenance under normal conditions.
Main Components:
Our state-of-the-art transformer is engineered with these critical components: Oil Tank, Conservator, Buchholz Relay, Breather Unit, Oil Indicator, Temperature Detector, Pressure Relief Device, Thermal Relay, Radiator, and Bushing.
1. The oil tank is essential for immersing the windings, ensuring optimal insulation and cooling.
2. Fully compliant with IEC standards and proudly certified with CE/ISO credentials.
3. Designed for quick contact and thermal expansion, allowing the oil temperature to adjust efficiently.
4. The Buchholz relay is crucial when a conservator tank is in use, detecting issues like low oil levels and improper oil flow between the tank and transformer.
5. The Breather Unit, containing silica gel, absorbs moisture from the oil. When the gel turns from blue to pink, it indicates saturation.
6. The oil indicator provides a clear measurement of the oil level in the conservatory unit.
7. The temperature detector continuously monitors oil temperature, disconnecting the transformer if it exceeds safe levels.
8. The pressure relief device mitigates internal pressure to prevent potential transformer explosions.
9. The thermal relay acts as a safeguard, indicating winding temperature to ensure safety and efficiency.
10. Covered with a full galvanized coating to ensure rust-free durability.
11. The bushing connects the internal windings with the external electrical network, ensuring seamless integration.
