Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series, a cutting-edge, fully sealed oil immersed power transformer crafted by Chaotai Power. This innovative transformer boasts remarkable benefits, including significantly reduced energy loss, minimal noise output, and exceptional operational efficiency. Designed for optimal energy conservation, it not only decreases pollution but also enhances sustainability. Unlike conventional oil immersed transformers, this state-of-the-art model eliminates the need for an oil conservator. Instead, it cleverly adapts to changes in oil volume through the flexible corrugated sheets of its oil tank, ensuring automatic adjustment and compensation. This clever design keeps the transformer protected from air exposure, thereby preventing rapid oil deterioration and insulation aging. As a result, operational reliability is significantly enhanced, and maintenance demands are minimized under normal operational conditions.
