Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series, a revolutionary fully sealed oil immersed power transformer meticulously crafted by Chaotai Power. This marvel of engineering is designed to offer unparalleled benefits including reduced loss, minimal noise, and exceptional efficiency. These advantages translate into a remarkable energy-saving performance while significantly lowering environmental pollution. Unlike ordinary oil immersed transformers, this fully sealed variant eliminates the need for an oil conservator. The ingenious design features a corrugated oil tank, where the elasticity of the corrugated sheet automatically adjusts and compensates for oil volume changes. Isolated completely from ambient air, this transformer dramatically slows oil deterioration and insulation aging, ensuring enhanced reliability and long-lasting operation without the need for routine maintenance.

The fully sealed oil immersed power transformer from Chaotai Power is expertly engineered for low energy loss, minimal noise, and outstanding efficiency. These attributes deliver superior energy savings and significantly reduce environmental impact.
In comparison to conventional oil immersed transformers, our fully sealed design eliminates the need for an oil conservator. This innovation allows the oil volume to be automatically adjusted via the elasticity of the corrugated oil tank's sheet, providing complete isolation from the air. This design helps in preventing and significantly slowing oil deterioration and insulation aging, thereby boosting operational reliability and eliminating the need for maintenance during regular operations.
