Product Description
Oil Immersed Series Transformer:
The S11-M series fully sealed oil immersed power transformer, proudly developed and produced by Chaotai Power, offers remarkable advantages including minimal loss, reduced noise, and superior efficiency. This translates into significant energy savings and lowered pollution. Unlike conventional oil immersed transformers, this fully sealed marvel eliminates the need for an oil conservator. Instead, it utilizes the corrugated oil tank's elastic corrugated sheet, which automatically adjusts and compensates for oil volume changes. This innovative design isolates the transformer from air, thereby preventing and delaying oil deterioration and insulation aging. The result is enhanced operational reliability and a maintenance-free performance during standard operations.

The fully sealed oil immersed power transformer by Chaotai Power is engineered for low loss, minimal noise, and high efficiency, delivering outstanding energy-saving performance and reducing environmental impact.
Designed to surpass the ordinary, the fully sealed transformer discards the conventional oil conservator. It adapts to oil volume changes automatically through the elasticity of the corrugated oil tank's sheet, maintaining isolation from air, thereby slowing oil degradation and insulation aging. This enhances reliability and ensures maintenance-free operation under standard conditions.
