Product Description
Oil Immersed Series Transformer:
Introducing the S11-M Series, a state-of-the-art fully sealed oil-immersed power transformer engineered by Zhejiang Chaotai Complete Equipment Co., Ltd. This innovative product stands out with its exceptional attributes of low loss, minimal noise, and remarkable efficiency, offering an outstanding energy-saving solution that actively contributes to pollution reduction. Unlike conventional oil-immersed transformers, this advanced model eliminates the need for an oil conservator. Instead, the volume of oil is deftly managed through the elasticity of the corrugated oil tank, making automatic adjustments to ensure seamless operation. By being isolated from air exposure, this transformer significantly inhibits oil deterioration and insulation aging, thereby bolstering operational reliability and virtually eliminating the need for maintenance during regular use.
