Product Description
Oil Immersed Series Transformer:
The S11-M series fully sealed oil immersed power transformer, innovatively crafted by Chaotai Power, stands out with its remarkable features of low loss, minimal noise, and exceptional efficiency. This advanced transformer promises impressive energy savings and contributes significantly to pollution reduction. Unlike traditional oil immersed transformers, our fully sealed design eliminates the need for an oil conservator. The transformer’s oil volume is ingeniously self-adjusting, adapting automatically via the elasticity of its corrugated oil tank sheets. By being completely air-isolated, it effectively slows down oil deterioration and prevents insulation aging, thereby boosting operational reliability and eliminating the need for maintenance during standard operation.

The pioneering fully sealed oil immersed power transformer by Chaotai Power delivers outstanding advantages such as low loss, reduced noise, and high efficiency, thereby ensuring excellent energy savings and effective pollution mitigation.
In contrast with conventional oil immersed transformers, our fully sealed counterparts dispense with the oil conservator. The elastic corrugated oil tank sheets allow automatic oil volume adjustments and ensure air isolation to decelerate oil degradation and insulation aging. This design significantly enhances operational reliability, facilitating maintenance-free normal operations.
