Product Description
Introducing the Oil Immersed Series Transformer:
The S11-M series fully sealed oil-immersed power transformer, crafted meticulously by Chaotai Power, stands out with its superior attributes of low loss, quiet operation, and exceptional efficiency. This translates into impressive energy-saving capabilities and a substantial reduction in environmental pollutants. In contrast to conventional oil-immersed transformers, our fully sealed design eliminates the need for an oil conservator. The transformer ingeniously regulates oil volume through the elasticity of the corrugated oil tank's sheet, enabling consistent and reliable performance. By being isolated from the air, it significantly delays oil degradation and insulation aging, thus boosting operational reliability and eliminating the need for regular maintenance.

Short-circuit Impedance: Engineered to meet Standard Impedance criteria.
Altitude Limitations: Crafted for use below 1000m altitude and temperatures not exceeding 40°C.
If conditions exceed these limits, we adjust parameters to align with established standards, ensuring optimal performance.
The fully sealed oil-immersed power transformer, a proud innovation of Chaotai Power, offers unparalleled benefits such as minimized loss, silent operation, and high efficiency, resulting in exceptional energy conservation and reduced environmental impact.
In comparison to standard models, our fully sealed transformer omits the oil conservator, allowing for self-adjustment of oil volume through a resilient corrugated tank. This design isolates the transformer from air, thereby slowing oil degradation and insulation aging, enhancing reliability, and obviating the need for frequent maintenance.
