Product Description
Oil Immersed Series Transformer:
Zhejiang Chaotai Complete Equipment Co., Ltd. proudly presents the S11-M series fully sealed oil immersed power transformer. Meticulously developed and produced by Chaotai Power, these state-of-the-art transformers boast exceptional features, including low loss, minimal noise, and heightened efficiency, delivering outstanding energy-saving benefits and pollution reduction. Unlike conventional oil immersed transformers, our fully sealed transformer innovatively eliminates the oil conservator. The oil volume variations are seamlessly adjusted and compensated through the elasticity of the corrugated sheet of the corrugated oil tank, ensuring the transformer remains isolated from air exposure. This clever design significantly slows down oil deterioration and insulation aging, thus enhancing operational reliability and negating the need for maintenance under normal conditions.
