Product Description
Introducing the Oil-Immersed Series Transformer: Your Source for Unmatched Power Efficiency
The S11-M series, a fully sealed oil-immersed power transformer crafted by Chaotai Power, stands out with its exceptional features: minimal energy loss, whisper-quiet operation, and superior efficiency. These transformers are specifically designed to deliver impressive energy savings while minimizing environmental impact. Unlike conventional oil-immersed transformers, our fully sealed variant eliminates the need for an oil conservator, as the oil volume adjusts automatically via the corrugated oil tank's flexible corrugated sheets. By being completely air-isolated, the transformer significantly slows oil degradation and insulation aging, thereby bolstering operational reliability and minimizing maintenance during standard operation.

4. Tapping Range: Provides ±5%, 2x2.5%, ±4x2.5% for optimum performance adjustments.
5. Frequency: Compatible with both 50Hz and 60Hz systems.
6. Phases: Available in both three-phase and single-phase configurations.
7. Connection Symbol: Configured as Dyn11, Yyn0, or tailored to specific requests.
8. Short-circuit Impedance: Designed with standard impedance for consistent performance.
9. Altitude: Operates efficiently at altitudes not exceeding 1000m, with ambient temperatures remaining below 40°C. If conditions exceed these, we tailor parameters to meet standard specifications.
In scenarios where conditions surpass the standard, our transformers are modulated to standard guidelines to ensure reliable operation.
Power capacity options range from 25 to 2500KVA to suit diverse energy needs.
Voltage Levels: Available in a wide spectrum including 10KV, 11KV, 13.8KV, 15KV, 17.5KV, 20KV, 22KV, 30KV, 33KV, 35KV, 36KV.
Voltage Level: Offering a variety of choices to cater to specific requirements.
Type of Voltage Regulation: Versatile options include Off-circuit or On-load for customized regulation.
Tapping Range: Provides flexibility with ±5%, ±2x2.5%, and ±4x2.5% adjustments.
Frequency: Designed to operate seamlessly at either 50Hz or 60Hz.
Phases: Offered in both three-phase and single-phase to meet varying power needs.
Connection Symbol: Configurable as Dyn11, Yyn0, or adapted as requested for compatibility.
Short-circuit Impedance: Engineered to standard impedance for reliable and efficient operation.
Operational Altitude: Capable of functioning effectively up to 1000m with temperatures not surpassing 40°C.
For conditions beyond these limits, parameter modulation is conducted in accordance with industry standards to guarantee consistent performance.
Chaotai Power's fully sealed oil-immersed power transformer is engineered with cutting-edge technology delivering reduced loss, low acoustic presence, and high operational efficiency, ensuring environmental benefits and reduced pollution footprint.
In a comparison with standard oil-immersed transformers, our fully sealed model removes the need for an oil conservator, offering automatic oil volume adjustment through the elastic properties of the tank's corrugated sheet. This innovative air isolation technique slows down oil deterioration and insulation aging, significantly enhancing operational reliability while minimizing maintenance needs during regular use.
