Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series, a meticulously engineered fully sealed oil-immersed power transformer by Zhejiang Chaotai Complete Equipment Co., Ltd. This exceptional product showcases remarkable features such as low energy loss, whisper-quiet operation, and unparalleled efficiency, driving superior energy savings while minimizing environmental impact. Unlike conventional oil-immersed transformers, our fully sealed design eliminates the need for an oil conservator, leveraging a corrugated oil tank that adapts to oil volume changes via its flexible corrugated sheet. This innovative isolation from external air significantly slows oil deterioration and prevents insulation aging, thereby ensuring enhanced operational reliability and maintenance-free performance.

Our fully sealed oil-immersed power transformer by Chaotai Power stands out with its low-loss, low-noise, and high-efficiency operation, achieving remarkable energy savings and reducing environmental pollution.
This advanced transformer design, unlike traditional models, removes the necessity for an oil conservator. Instead, it employs a corrugated oil tank whose flexible design compensates automatically for oil volume changes. Its airtight separation from the environment prevents oil degradation and insulation aging, boosting reliability and eliminating the need for regular maintenance.
