Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series fully sealed oil immersed power transformer, a remarkable innovation by Chaotai Power. This transformer is engineered with low loss, minimal noise, and exceptional efficiency, ensuring significant energy savings and minimal environmental impact. Unlike traditional oil-immersed transformers, this advanced model eliminates the need for an oil conservator. The oil volume variations are smartly managed by the flexible corrugated sheets of the oil tank, automatically adapting to changes. With complete isolation from air, this transformer excellently prevents oil degradation and insulation wear, greatly boosting operational reliability and eliminating the need for maintenance under normal conditions.

Type of Voltage Regulation: Selectable Off-circuit or On-load regulation modes.
Tapping Range: Options include ±5% and ±2x2.5% or ±4x2.5% for tailored voltage adjustments.
Frequency: Compatible with both 50Hz or 60Hz power systems.
Phases: Designed for three-phase or single-phase applications.
Connection Symbol: Flexible choices between Dyn11, Yyn0 (or customized upon request).
Short-circuit Impedance: Maintained at standard levels for optimal functionality.
Altitude Suitability: Designed for locations not surpassing 1000m in altitude and with ambient temperatures under 40°C.
In cases where these environmental conditions are not met, we adjust the transformer parameters according to industry standards.
The fully sealed oil immersed power transformer by Chaotai Power is synonymous with low loss, reduced noise levels, and superior efficiency. It promises excellent energy savings and decreased pollution, representing a leap forward in sustainable technology.
In comparison to conventional oil-immersed transformers, this sealed design removes the need for an oil conservator. The elasticity of the corrugated oil tank sheets regulates oil volume changes automatically. This design keeps the transformer fully air-isolated, thereby significantly delaying oil degradation and insulation aging, enhancing operational reliability, and removing the need for maintenance during normal operations.
