Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series fully sealed oil-immersed power transformer by Chaotai Power! This exceptional transformer boasts remarkable features like low loss, minimal noise, and outstanding efficiency, ensuring a substantial energy-saving impact while minimizing pollution. Unlike ordinary oil-immersed transformers, this cutting-edge fully sealed variant eliminates the need for an oil conservator. Instead, it ingeniously utilizes the elasticity of the corrugated sheet within the corrugated oil tank to automatically adjust and compensate for changes in oil volume. Isolated from air exposure, it significantly mitigates oil deterioration and insulation aging, thereby enhancing operational reliability and ensuring maintenance-free performance during standard operations.

The fully sealed oil-immersed power transformer by Chaotai Power is designed for low loss, low noise, and high efficiency, achieving superb energy-saving results while minimizing environmental impact.
In contrast to standard oil-immersed transformers, the revolutionary fully sealed design eliminates the oil conservator. The oil volume adaptation and compensation are seamlessly managed by the corrugated sheet's elasticity within the oil tank, isolating the transformer from air. This isolation effectively prevents oil deterioration and insulation aging, boosting operational reliability and eliminating the need for routine maintenance.
