Product Description
Oil Immersed Series Transformer:
Presenting the S11-M Series Fully Sealed Oil Immersed Power Transformer by Chaotai Power, a marvel of engineering renowned for its low loss, low noise, and high efficiency. This exceptional design not only delivers superior energy-saving performance but also significantly reduces pollution. Unlike conventional transformers, our fully sealed model eliminates the need for an oil conservator. The oil volume changes are self-regulated and compensated by the flexible corrugated sheet within the oil tank. This innovative design isolates the transformer from air exposure, thereby preventing oil deterioration and insulation aging, while enhancing operational reliability and minimizing the need for maintenance.

Our fully sealed oil immersed power transformer by Chaotai Power boasts remarkable advantages such as low energy loss, minimal noise, and exceptional efficiency, culminating in outstanding energy conservation and reduced environmental impact.
In contrast to standard oil immersed transformers, our fully sealed design eliminates the need for an oil conservator. The oil volume adjustments are automatically managed by the elasticity of the corrugated oil tank sheet. This construction ensures the transformer remains isolated from air, mitigating oil degradation and insulation wear, while also boosting operational dependability and reducing maintenance requirements.
