Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series, an extraordinary fully sealed oil-immersed power transformer, designed and meticulously manufactured by Zhejiang Chaotai Complete Equipment Co., Ltd. This transformative innovation excels with its remarkable qualities of low energy loss, whisper-quiet operation, and unparalleled efficiency. It provides a leading-edge, energy-conserving solution that drastically reduces pollution and minimizes environmental impact. Diverging from conventional oil-immersed transformers, this avant-garde model entirely removes the necessity for an oil conservator. Through the elasticity of its corrugated oil tank, the design intelligently self-regulates and compensates for oil volume changes, ensuring the transformer remains hermetically sealed from air exposure. This revolutionary feature safeguards the oil from degradation, prolongs insulation lifespan, and significantly boosts operational reliability, while removing the burden of maintenance during routine operations.

The fully sealed oil-immersed power transformer, a crowning achievement of Chaotai Power, offers unparalleled low energy loss, serene operation, and exceptional efficiency. It provides an outstanding energy-saving solution that drastically reduces pollution.
Unlike traditional oil-immersed transformers, this entirely sealed design does away with the oil conservator. It autonomously handles oil volume changes through the elasticity of the corrugated oil tank sheet, ensuring the transformer stays isolated from air. This critical feature not only protects against oil deterioration and insulation aging but also enhances reliability and negates the requirement for regular maintenance.
