Product Description
Oil Immersed Series Transformer:
The S11-M series fully sealed oil immersed power transformer, proudly developed and produced by Chaotai Power, boasts remarkable features such as low loss, minimal noise, and exceptional efficiency. These attributes ensure superior energy-saving performance while significantly reducing pollution. Unlike conventional oil immersed transformers, this advanced model features a fully sealed design that eliminates the oil conservator. The transformative change in oil volume is seamlessly adjusted and compensated by the corrugated sheet's elasticity within the corrugated oil tank. This innovative design isolates the transformer from air exposure, effectively preventing and decelerating oil deterioration and insulation aging. As a result, it enhances operation reliability and eliminates the need for maintenance during normal operation.

Chaotai Power's fully sealed oil immersed power transformer stands out with its low loss, low noise, and high efficiency, delivering impressive energy-saving results and reducing environmental pollution.
In contrast to regular oil immersed transformers, this innovative fully sealed model eliminates the need for an oil conservator. The elastic properties of the corrugated sheet within the tank automatically adjust and compensate for changes in oil volume. This design effectively isolates the transformer from air exposure, thereby slowing oil deterioration and insulation aging, enhancing reliability, and negating the need for routine maintenance.
