Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series fully sealed oil-immersed power transformer, meticulously crafted by Chaotai Power. This innovative transformer is designed to offer remarkable benefits, including reduced energy loss, decreased noise levels, and superior efficiency. These features culminate in substantial energy savings and minimized environmental impact. This advanced transformer distinguishes itself from conventional oil-immersed models by eliminating the oil conservator. Instead, it utilizes the flexible corrugated sheet of the oil tank to automatically adjust and compensate for changes in oil volume. Isolated from the air, this design not only mitigates oil deterioration and insulation aging but also significantly improves operational reliability, effectively eliminating the need for maintenance during standard operations.

The fully sealed oil-immersed power transformer by Chaotai Power boasts low energy loss, minimal noise, and high efficiency, ensuring significant energy savings and reduced pollution.
Unlike typical oil-immersed transformers, this fully sealed model removes the need for an oil conservator. It smartly adapts to oil volume changes through the elasticity of the corrugated oil tank. By isolating the transformer from air exposure, it effectively prevents oil degradation and insulation aging, enhancing reliability and eliminating maintenance needs during normal operation.
