Product Description
Oil Immersed Series Transformer:
The S11-M series fully sealed oil immersed power transformer, meticulously developed and crafted by Chaotai Power, stands out with its remarkable advantages of reduced loss, minimal noise, and heightened efficiency. This translates into significant energy savings and a reduction in pollution. Unlike the conventional oil-immersed transformer, this innovative fully sealed design eliminates the need for an oil conservator. The change in oil volume is seamlessly managed and adjusted by the corrugated oil tank's elastic corrugated sheet. Being completely isolated from air exposure, it effectively slows down oil degradation and insulation aging, thereby enhancing operational reliability and eliminating the need for maintenance during normal operations.

The fully sealed oil immersed power transformer, innovatively developed by Chaotai Power, boasts of low loss, quiet operation, and exceptional efficiency. It serves as a powerful energy-saving solution that mitigates pollution.
In a departure from traditional oil-immersed transformers, this fully sealed variant eliminates the oil conservator. The oil volume changes are cleverly managed by the elasticity of the corrugated oil tank's sheet. Its design ensures total isolation from air, preventing oil degradation and insulation aging, thus bolstering operational reliability and negating the need for routine maintenance.
