Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series fully sealed oil-immersed power transformer, an innovation by Chaotai Power, designed with excellence to deliver numerous advantages such as low loss, minimal noise output, and high efficiency. This translates into outstanding energy-saving capabilities and pollution reduction. In comparison to typical oil-immersed transformers, our fully sealed design eliminates the need for an oil conservator. Instead, the oil volume is ingeniously adjusted and compensated by the elastic corrugated sheet within the corrugated oil tank. This cutting-edge feature ensures the transformer remains hermetically sealed from the air, effectively mitigating oil deterioration and insulation aging. Consequently, it enhances operational reliability and eliminates the necessity for maintenance during standard operations.

The fully sealed oil-immersed power transformer, a pioneering creation by Chaotai Power, boasts remarkable attributes of low loss, reduced noise, and impressive efficiency, ensuring exceptional energy savings and a smaller environmental footprint.
By eliminating the oil conservator, the fully sealed transformer distinguishes itself from conventional oil-immersed types. The corrugated oil tank's elasticity automatically adjusts oil volume changes, isolating the transformer from air exposure. This innovative approach significantly slows oil deterioration and insulation aging, boosting operational reliability and negating maintenance during typical operations.
