Product Description
Oil Immersed Series Transformer:
The S11-M series of fully sealed oil-immersed power transformers, innovatively crafted and produced by Chaotai Power, boast exceptional features such as low loss, minimal noise, and remarkable efficiency. These attributes collectively deliver an outstanding energy-saving performance while significantly minimizing environmental impact. Unlike conventional oil-immersed transformers, the fully sealed variant discards the oil conservator, employing a corrugated oil tank's elasticity to automatically adjust and compensate for oil volume changes. This seamless sealing isolates the transformer from atmospheric contact, dramatically slowing down oil degradation and insulation aging, thereby boosting operational reliability and negating the need for regular maintenance under normal conditions.

If standard conditions cannot be met, we ensure parameter modulation to comply with industry standards.
Chaotai Power's fully sealed oil-immersed transformers are engineered for excellence, offering low loss, minimal noise, and superior efficiency. This combination achieves remarkable energy savings and reduced environmental impact.
In contrast to standard oil-immersed transformers, the fully sealed design eliminates the oil conservator. Oil volume changes are seamlessly managed by the corrugated oil tank's elasticity. With full air isolation, this innovative design significantly retards oil degradation and insulation aging, enhancing operational reliability and eliminating regular maintenance requirements under typical conditions.
