Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series, the epitome of advanced transformer technology crafted by Chaotai Power. This fully sealed oil-immersed power transformer is engineered to deliver outstanding performance characterized by low loss, whisper-quiet operation, and remarkable efficiency. These attributes culminate in a substantial energy-saving effect and a tangible reduction in pollution. The innovation lies in its design: unlike typical oil transformers, this model eliminates the need for an oil conservator. Instead, it boasts a flexible corrugated oil tank that self-adjusts the oil volume through its resilient corrugated sheets, ensuring seamless pressure management. Completely isolated from external air, this transformer staves off the deterioration of oil and delays insulation aging, thereby enhancing operational reliability and minimizing the need for maintenance during standard use.

Chaotai Power's fully sealed oil-immersed transformers stand out with their minimal loss, reduced noise levels, and exceptional efficiency, effectively contributing to energy savings and environmental protection.
The revolutionary design of the fully sealed transformer eliminates the conventional oil conservator, with oil volume dynamically managed by the elasticity of the tank's corrugated sheets. This innovative approach isolates the transformer from atmospheric exposure, significantly mitigating oil degradation and insulation wear, thereby boosting operational dependability and eliminating the need for routine maintenance.
