Product Description
Oil Immersed Series Transformer:
Introducing the cutting-edge S11-M series fully sealed oil immersed power transformer, a hallmark of innovation by Chaotai Power. This transformer stands out for its exceptional low loss, minimal noise emission, and superior efficiency, offering exemplary energy-saving capabilities while significantly reducing environmental impact. Unlike conventional oil immersed transformers, our fully sealed variant eliminates the need for an oil conservator. The innovative design allows the oil volume changes to be automatically adjusted and compensated through the elasticity of the corrugated sheet within the corrugated oil tank. This unique feature ensures that the transformer remains isolated from the atmosphere, effectively mitigating oil deterioration and insulation aging, thereby enhancing operational reliability and doing away with the need for regular maintenance under standard operating conditions.

Chaotai Power's fully sealed oil immersed power transformers boast advanced features like low loss, reduced noise, and high efficiency, delivering outstanding energy-saving performance while minimizing environmental pollution.
In contrast to traditional oil immersed transformers, our fully sealed model eliminates the oil conservator. The fluctuation in oil volume is automatically controlled by the corrugated sheet's elasticity within the corrugated oil tank. This isolation from the atmosphere effectively slows down oil and insulation aging, boosts operational reliability, and eliminates routine maintenance during normal operation.
