Product Description
Oil Immersed Series Transformer:
The S11-M series fully sealed oil-immersed power transformer, crafted by Chaotai Power, stands out with its remarkable attributes of reduced loss, minimal noise, and superior efficiency. This innovative design not only ensures substantial energy savings but also significantly curtails pollution. Unlike conventional transformers, this advanced model eliminates the need for an oil conservator. The ingenious flexibility of the corrugated oil tank's sheet allows for automatic adjustment and compensation of oil volume changes. Fully isolated from air, this transformer effectively prevents oil deterioration and insulation aging, thereby enhancing operational reliability and eliminating the need for maintenance during normal operation.
