Product Description
Oil Immersed Series Transformer:
The S11-M Series, a state-of-the-art fully sealed oil immersed power transformer from Chaotai Power, stands out for its remarkable features: low loss, minimal noise, and exceptional efficiency. This results in significant energy savings and reduced environmental impact. Unlike traditional oil immersed transformers, this advanced model eliminates the need for an oil conservator. It ingeniously utilizes the elasticity of the corrugated sheet in the oil tank to automatically adjust and compensate for oil volume changes. This innovative design ensures the transformer remains sealed from atmospheric contact, effectively preventing oil deterioration and insulation aging. It enhances operational reliability and eliminates maintenance requirements under normal conditions, offering a maintenance-free experience.

Chaotai Power's fully sealed oil immersed power transformer is engineered for exceptional performance, offering low loss, reduced noise, and high efficiency, delivering significant energy savings and minimizing environmental impact.
In contrast to conventional oil immersed transformers, the fully sealed model eliminates the oil conservator, leveraging the elasticity of the corrugated sheet in the oil tank to dynamically manage oil volume changes. This ensures isolation from air, thereby preventing oil degradation and insulation aging, enhancing operational reliability, and enabling maintenance-free operation.
