Product Description
Oil Immersed Series Transformer:
The S11-M series fully sealed oil-immersed power transformer, crafted by Chaotai Power, stands out for its remarkable features: low loss, minimal noise, and exceptional efficiency. These characteristics not only promise significant energy conservation but also contribute to environmental sustainability by reducing pollution. Unlike traditional oil-immersed transformers, this advanced fully-sealed model eliminates the need for an oil conservator. The ingenious design ensures that the changing oil volume is adjusted and compensated automatically by the flexible corrugated sheet within the corrugated oil tank. This innovation isolates the transformer from air exposure, effectively preventing oil deterioration and insulation aging. As a result, operational reliability is vastly improved, offering maintenance-free convenience during normal operations.

Chaotai Power's fully sealed oil-immersed power transformer is an engineering marvel that offers low loss, minimal noise, and impeccable efficiency. This innovative design not only enhances energy savings but also significantly curtails pollution levels.
In contrast to conventional oil-immersed transformers, this cutting-edge fully sealed variant eliminates the need for an oil conservator. The dynamic design ensures oil volume changes are automatically managed through the elasticity of the corrugated oil tank sheet. This setup effectively isolates the transformer from direct air exposure, thereby protecting against oil degradation and insulation aging. Consequently, it bolsters operational reliability and negates the need for regular maintenance under standard operating conditions.
