Product Description
Oil immersed series transformer:
The S11-M series, a hallmark of Chaotai Power's innovation, is a fully sealed oil-immersed power transformer that stands out for its remarkable low loss, low noise, and high efficiency. These attributes collectively foster excellent energy-saving performance, significantly cutting down pollution levels. This advanced design distinguishes itself from conventional oil-immersed transformers by eliminating the oil conservator. Instead, it features an adaptive mechanism where oil volume variations are seamlessly managed by the corrugated oil tank's elastic corrugated sheet. This unique feature ensures the transformer remains isolated from air exposure, thereby decelerating oil degradation and insulation aging. Consequently, this enhances reliability and minimizes maintenance needs during standard operations.
