Product Description
Oil Immersed Series Transformer:
The S11-M series, an exceptional fully sealed oil-immersed power transformer crafted by Chaotai Power, boasts remarkable advantages such as low loss, minimal noise, and supreme efficiency. These features ensure outstanding energy conservation and pollution reduction. Unlike ordinary oil-immersed transformers, this fully sealed marvel omits the oil conservator, with oil volume changes seamlessly managed and compensated by the corrugated oil tank's elastic corrugated sheet. This innovative design isolates the transformer from air, thereby preventing and delaying oil deterioration and insulation aging, enhancing operational reliability, and eliminating the need for maintenance during normal operation.
