Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series fully sealed oil immersed power transformer by Chaotai Power, a marvel of modern engineering that promises minimal energy loss, whisper-quiet operation, and outstanding efficiency. This state-of-the-art transformer is designed to deliver exceptional energy-saving results and significantly reduce environmental impact. Unlike conventional models, our fully sealed design eliminates the need for an oil conservator. Changes in oil volume are seamlessly adjusted by the corrugated oil tank's flexible corrugated sheet, making the unit impervious to air exposure. This isolation effectively prolongs oil life, mitigates insulation aging, boosts operational durability, and typically requires no maintenance during standard operations.

Our fully sealed oil immersed power transformer by Chaotai Power offers low loss, low noise, and high efficiency for exemplary energy savings and reduced environmental footprint.
Differing from traditional oil immersed transformers, our fully sealed design eliminates the oil conservator. Variations in oil volume are automatically balanced by the corrugated oil tank's resilient design, ensuring the unit remains isolated from air exposure. This isolation slows oil degradation and insulation aging, enhances operational reliability, and typically eliminates the need for maintenance during regular use.
