Product Description
Oil Immersed Series Transformer:
Introducing the transformative S11-M series, a hallmark of technological excellence in oil-immersed power transformers, meticulously engineered by Zhejiang Chaotai Complete Equipment Co., Ltd. This extraordinary transformer is replete with distinguishing features including its remarkable low energy dissipation, whisper-quiet operational sound, and unparalleled efficiency. It is the epitome of an energy-conserving marvel, significantly diminishing pollution and environmental repercussions. Diverging from conventional oil-immersed variants, this advanced model does away with the oil conservator requirement.

The fully sealed oil-immersed power transformer, an embodiment of innovation by Chaotai Power, exhibits low energy loss, silent operation, and exceptional efficiency. It stands as a prime energy-saving solution significantly reducing environmental pollution.
Contrasting traditional oil-immersed transformers, this fully sealed design eliminates the need for an oil conservator. It autonomously regulates oil volume changes with the elasticity of the corrugated oil tank, ensuring the transformer remains isolated from air. This critical feature not only prevents oil deterioration and insulation aging but also enhances reliability and negates the need for routine maintenance.
