Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series, a fully sealed oil-immersed power transformer, meticulously engineered and produced by Zhejiang Chaotai Complete Equipment Co., Ltd. This exceptional transformer is distinguished by its outstanding features of low energy consumption, minimal noise, and superior efficiency. It serves as a prime energy-saving solution, dramatically minimizing environmental pollution and impact. Departing from conventional oil-immersed models, this forward-thinking design eliminates the necessity for an oil conservator. The ingenious configuration allows autonomous adjustment and compensation for oil volume variations via the flexibility of the corrugated oil tank, safeguarding the transformer from air contact. This pioneering feature halts oil degradation, slows the aging of insulation, and significantly boosts operational reliability, all while negating the need for maintenance during regular operations.

The fully sealed oil-immersed power transformer, an innovative marvel by Chaotai Power, is characterized by low energy loss, quiet operation, and high efficiency. It provides an exceptional energy-saving solution that greatly reduces pollution.
Unlike traditional oil-immersed transformers, this fully sealed configuration eradicates the need for an oil conservator. It autonomously adjusts and manages oil volume changes with the elasticity of the corrugated oil tank sheet, ensuring the transformer remains isolated from air exposure. This critical feature not only prevents oil degradation and slows insulation aging but also enhances reliability and eliminates the necessity for regular maintenance.
