Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series fully sealed oil-immersed power transformer, designed and meticulously crafted by Chaotai Power. It boasts outstanding features such as low loss, minimal noise, and exceptional efficiency, ensuring remarkable energy-saving potential while contributing to pollution reduction. Unlike traditional oil-immersed transformers, this innovative design eliminates the need for an oil conservator. The volume changes in oil are effortlessly managed by the flexible, corrugated sheet within the oil tank, maintaining a seal against air to prevent oil degradation and insulation aging. This guarantees enhanced operational reliability and eliminates the need for maintenance under standard operating conditions.
