Product Description
Oil Immersed Series Transformer:
The S11-M series fully sealed oil immersed power transformer, meticulously engineered by Chaotai Power, boasts a remarkable combination of low loss, minimal noise, and exceptional efficiency. This innovative transformer not only delivers superior energy-saving capabilities but also contributes substantially to pollution reduction. Unlike traditional oil-immersed transformers, this advanced model has eliminated the need for an oil conservator. Instead, it ingeniously uses the corrugated oil tank's flexible sheets to automatically adjust and compensate for oil volume changes. By being completely isolated from the surrounding air, this transformer significantly slows down oil deterioration and insulation aging, thereby enhancing operational reliability and ensuring maintenance-free performance under normal conditions.

Chaotai Power's fully sealed oil immersed power transformer is a masterpiece of engineering excellence, offering outstanding low loss, low noise, and impressive efficiency. It stands as a beacon of energy conservation and environmental stewardship by significantly reducing pollution.
When compared to standard oil-immersed transformers, this fully sealed variant eliminates the need for an oil conservator. Changes in oil volume are automatically managed through the elasticity of the corrugated oil tank sheets, ensuring the transformer remains isolated from outside air. This design choice greatly mitigates the effects of oil deterioration and insulation aging, enhancing reliability and negating the need for maintenance during standard operation.
