Product Description
Oil Immersed Series Transformer:
The S11-M series fully sealed oil-immersed power transformer, crafted by Chaotai Power, epitomizes advanced engineering with its exceptional attributes of low loss, minimal noise, and impressive efficiency. This design not only promotes significant energy savings but also contributes to environmental sustainability by reducing pollution. Unlike conventional oil-immersed transformers, this innovative model eliminates the need for an oil conservator. The genius of its design lies in the corrugated oil tank that automatically adjusts and compensates for changes in oil volume through its elastic corrugated sheet. The transformer is expertly shielded from air exposure, preventing the degradation of oil and slowing insulation aging. This enhances operational reliability and ensures maintenance-free performance during standard operations.
