Product Description
Oil Immersed Transformer Series:
Introducing the S11-M series, a fully sealed oil immersed power transformer by Chaotai Power that stands out with its remarkable features: low loss, low noise, and exceptional efficiency. This innovative design not only delivers substantial energy savings but also curtails environmental pollution. Unlike traditional oil-immersed transformers, our fully sealed models eliminate the need for an oil conservator. The oil volume changes are ingeniously managed by the flexible corrugated sheet of the oil tank, ensuring optimal performance. By isolating the transformer from ambient air, it significantly delays oil deterioration and insulation aging, thereby enhancing operational reliability and reducing the need for maintenance under normal operating conditions.
