Product Description
Oil Immersed Series Transformer:
Introducing the S11-M Series Fully Sealed Oil Immersed Power Transformer by Chaotai Power. This innovative transformer offers remarkable advantages such as low loss, minimal noise, and impressive high efficiency, contributing to outstanding energy-saving results and pollution reduction. Unlike conventional oil-immersed transformers, our fully sealed design eliminates the need for an oil conservator, with oil volume changes cleverly managed and compensated by the flexible corrugated sheet of the tank. This design isolates the transformer from the air, effectively delaying oil deterioration and insulation aging, thereby enhancing operational reliability and ensuring maintenance-free performance during normal operations.
