Product Description
Oil Immersed Series Transformer:
The S11-M series fully sealed oil immersed power transformer, a remarkable innovation by Chaotai Power, boasts an array of significant advantages: low loss, minimal noise, and exceptional efficiency. This transformative design ensures excellent energy conservation and significantly reduces environmental pollution. Unlike conventional oil-immersed transformers, this cutting-edge model eliminates the need for an oil conservator. Its oil volume is deftly managed by the flexible corrugated sheets of its oil tank, allowing for automatic adjustments and compensation. By being hermetically sealed from the air, it dramatically curtails oil degradation and insulation aging, thus enhancing operational reliability and negating the need for regular maintenance under normal conditions.

Short-circuit Impedance: Adheres to Standard Impedance.
Environmental Compatibility: Operates below 1000m altitude and 40°C temperature. Adjustments will be made if these conditions are exceeded.
If specified environmental conditions are not met, adjustments will be modulated in accordance with industry standards.
This fully sealed oil immersed power transformer, crafted by Chaotai Power, excels in delivering low loss and noise while achieving high efficiency. It is a beacon of energy conservation and pollution reduction.
Setting itself apart from traditional oil immersed transformers, this fully sealed design eliminates the oil conservator. Its oil volume adjusts automatically thanks to the corrugated oil tank's elasticity, keeping it isolated from air, which effectively slows oil deterioration and insulation aging. This enhances reliability and virtually eliminates routine maintenance needs under normal operating conditions.
