Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series, a state-of-the-art fully sealed oil-immersed power transformer developed and meticulously crafted by Chaotai Power. This innovative transformer boasts remarkable attributes such as low loss, minimal noise, and exceptional efficiency, ensuring an outstanding energy-saving impact while significantly reducing environmental pollution. Unlike traditional oil-immersed transformers, this fully sealed marvel eliminates the need for an oil conservator. The oil volume modifies automatically, thanks to the flexible elasticity of its corrugated oil tank sheets. Completely isolated from air, it effectively curbs oil deterioration and insulation aging, boosting operational reliability and eliminating the need for maintenance under normal operating conditions.

4. Tapping Range: Customized tapping options include ±5 %, ±2x2.5 %, ±4x2.5 % for precise operational control.
5. Frequency: Designed to operate seamlessly at either 50Hz or 60Hz, ensuring versatility in application.
6. Phases: Available in both three-phase and single-phase configurations to suit varying power needs.
7. Connection Symbol: Flexibility to choose between Dyn11, Yyn0, or any specific requests to match system requirements.
8. Short-circuit Impedance: Adheres to standardized impedance levels for enhanced safety and reliability.
Altitude and Temperature: Altitude should not exceed 1000m, and the ambient temperature must not surpass 40°C. For conditions beyond these parameters, we will tailor adjustments in line with standard protocols.
Adapting to Standards: In instances where standard conditions are not met, we will modulate parameters to comply with established standards, ensuring optimal performance.
Power Capacity: Ranging from 25-2500KVA to cater to various power demands.
Voltage Levels: Featuring options ranging from 10KV, 11KV, 13.8KV, 15KV, 17.5KV, 20KV, 22KV, 24KV, 30KV, 33KV, 35KV, to 36KV, providing comprehensive voltage flexibility.
Voltage Level:
Type of Voltage Regulation: Offers the choice between Off-circuit or On-load regulation for desired operational control.
Tapping Range: Allows for precise adjustments with ±5%, ±2x2.5%, and ±4x2.5% options.
Frequency: Compatible with both 50Hz and 60Hz frequencies to meet global standards.
Phases: Adaptable to both three-phase and single-phase power systems.
Connection Symbol: Options available for Dyn11, Yyn0, or customized according to specific system needs.
Short-circuit Impedance: Compliant with standard impedance requirements for dependable performance.
Environmental Conditions: Suitable for altitudes not exceeding 1000m and ambient temperatures up to 40°C.
Adjustments for Non-standard Conditions: Should these conditions not be met, parameters will be adjusted in accordance with the standard to ensure reliable operation.
Our fully sealed oil-immersed power transformer, expertly developed and produced by Chaotai Power, offers outstanding advantages including reduced loss, quiet operation, and high efficiency, delivering substantial energy savings while minimizing environmental impact.
Distinct from conventional oil-immersed transformers, this fully sealed design eliminates the oil conservator. The system intelligently adjusts oil volume via the corrugated oil tank's elastic properties, preventing air exposure, delaying oil decay and insulation wear, enhancing reliability, and negating the necessity for routine maintenance.
