Product Description
Oil Immersed Series Transformer:
The S11-M series fully sealed oil immersed power transformer, ingeniously engineered by Zhejiang Chaotai Complete Equipment Co., Ltd., offers remarkable advantages including minimal loss, whisper-quiet operation, and unparalleled efficiency. This transformer achieves outstanding energy conservation and significantly reduces environmental impact. Unlike conventional oil immersed transformers, this fully sealed marvel eliminates the need for an oil conservator. It automatically adjusts and compensates for oil volume changes through the smart elasticity of its corrugated oil tank. By isolating the transformer from the air, it effectively prevents oil deterioration and insulation aging, thereby enhancing reliability and minimizing maintenance demands during normal operation.

Our advanced fully sealed oil immersed power transformer, crafted by Chaotai Power, benefits from efficiencies like low loss and noise, achieving exceptional energy savings while minimizing pollution.
In comparison to traditional oil immersed transformers, our fully sealed model dispenses with the oil conservator. It self-regulates oil volume shifts using the corrugated oil tank's elasticity. This design innovation isolates the transformer from external air, significantly slowing oil degradation and insulation aging, thus bolstering operational reliability and diminishing the need for routine maintenance.
