Product Description
Oil Immersed Series Transformer:
The S11-M series fully sealed oil-immersed power transformer, meticulously developed and produced by Chaotai Power, offers remarkable advantages including low loss, minimal noise, and outstanding efficiency. These features contribute to excellent energy-saving effects and reduced pollution. Unlike conventional oil-immersed transformers, this fully sealed variant eliminates the oil conservator, leveraging the elasticity of the corrugated oil tank sheets to automatically adjust and compensate for changes in oil volume. This isolation from air effectively prevents and significantly slows down oil deterioration and insulation aging, thereby enhancing operational reliability and eliminating the need for maintenance during normal operations.

Voltage Level: Available in 10KV, 11KV, 13.8KV, 15KV, 17.5KV, 20KV, and 22KV options. 3. Type of Voltage Regulation: Choose between Off-circuit or On-load regulation types.
4. Tapping Range: Flexible options including ±5%, ±2x2.5%, and ±4x2.5%.
5. Frequency: Compatible with either 50Hz or 60Hz.
6. Phases: Available in three-phase or single-phase configurations.
7. Connection Symbol: Configurable as Dyn11, Yyn0, or as requested by the client.
8. Short-Circuit Impedance: Adheres to standard impedance guidelines.
9. Altitude is not exceeding 1000m, ambient temperature not exceeding 40°C. If it can't meet such conditions, we will modulate parameters in accordance with standard.
If standard environmental conditions are not met, we will adjust parameters accordingly.

The fully sealed oil-immersed power transformer, a hallmark of Chaotai Power, boasts advantages of low loss, low noise, and high efficiency, fostering significant energy saving and pollution reduction.
In contrast to traditional oil-immersed transformers, this fully sealed model eliminates the oil conservator, instead relying on the corrugated oil tank's elasticity to address oil volume fluctuations. This design effectively isolates the transformer from air, curbing oil deterioration and insulation aging, thus heightening operation reliability and obviating maintenance during standard operations.
