The rated voltage of our Custom Oil-Immersed Electrical Transformer 50 kVA Copper can be precisely tailored to meet the unique specifications and requirements of our esteemed customers.
The state-of-the-art, fully sealed oil-immersed power transformer, meticulously engineered by TSTY ELECTRIC CO., LTD., boasts innovative features that set it apart in the industry.
This transformer offers exceptional advantages, including low loss, minimal noise, and unparalleled efficiency. Such features ensure remarkable energy-saving performance and significantly mitigate environmental pollution. Unlike conventional oil-immersed transformers, our fully sealed model eliminates the need for an oil conservator. The intelligent design allows the oil volume to be automatically adjusted and compensated by the elasticity of the corrugated oil tank sheets. This ensures the transformer remains isolated from the atmosphere, thus preventing oil degradation and insulation aging. Consequently, it enhances operational reliability and ensures maintenance-free operation under normal conditions.
Key Components:
The primary parts of this Custom Oil-Immersed Electrical Transformer include: Oil Tank, Conservator, Buchholz Relay, Breather Unit, Oil Indicator, Temperature Detector, Pressure Relief Device, Thermal Relay, Radiator, and Bushing.
1. The oil tank is designed to fully immerse the windings, ensuring optimal cooling and insulation.
2. Manufactured to comply with IEC standards, and proudly certified with CE/ISO.
3. Facilitates easy contact and expansion during loading, allowing the oil temperature to rise and fall efficiently.
4. The Buchholz relay, essential when a conservator tank is employed, alerts to issues like oil levels dropping or improper oil flow between the tank and transformer.
5. The Breather Unit, containing silica gel, absorbs moisture from the oil. Its color change from blue to pink indicates saturation and the need for replacement.
6. The oil indicator provides real-time monitoring of the oil level within the conservator unit.
7. The temperature detector tracks the oil temperature, disconnecting the transformer from service if temperatures rise beyond safe limits.
8. The pressure relief device reduces internal pressure to prevent transformer explosions.
9. The thermal relay acts as a temperature indicator for the winding, ensuring reliable performance.
10. Fully galvanized coating ensures robust rust prevention.
11. The bushing connects the internal windings of the transformer to the external electrical network securely and efficiently.
