Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series fully sealed oil-immersed power transformer, a masterpiece developed and produced by Chaotai Power. This innovative transformer boasts exceptional qualities, including remarkably low loss, significantly reduced noise, and unparalleled efficiency. These features not only enhance energy-saving capabilities but also contribute to minimizing environmental pollution. Unlike conventional oil-immersed transformers, our fully sealed design eliminates the need for an oil conservator. The volume of oil within is smartly managed through the elasticity of the corrugated oil tank's sheet, automatically adjusting and compensating for any changes. This clever isolation from the air prevents and slows down oil degradation and insulation aging, thereby boosting operational reliability and eliminating the need for maintenance during regular use.

The fully sealed oil-immersed power transformer by Chaotai Power exemplifies excellence with its low loss, reduced noise, and extraordinary efficiency. It is a leader in energy conservation and pollution reduction.
In stark contrast to standard oil-immersed transformers, our fully sealed transformer eliminates the oil conservator. The oil volume changes are expertly managed by the elasticity of the corrugated oil tank, ensuring seamless adjustment and compensation. By isolating the transformer from air exposure, we effectively hinder oil degradation and insulation aging, thereby enhancing operational reliability and negating the need for routine maintenance.
