Hermetically Sealed Oil-Immersed Transformer

The S11-M series of 10/20kV hermetically sealed oil-immersed power transformers offer advantages such as low loss, low noise, and high efficiency. Compared to conventional oil-immersed transformers, the hermetically sealed design eliminates the oil conservator. The expansion and contraction of the oil volume are accommodated by the elastic orrugated panels in the corrugated tank. By isolating the transformer from the atmosphere, this design prevents and slows down the deterioration of the oil and the aging of insulation, thereby enhancing operational reliability.
