Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series fully sealed oil-immersed power transformer, proudly developed and manufactured by Chaotai Power. This state-of-the-art transformer boasts remarkable features such as low loss, minimal noise, and exceptional efficiency, making it a beacon of energy-saving excellence and environmental responsibility. Unlike conventional oil-immersed transformers, our innovative fully sealed design eliminates the need for an oil conservator. The oil volume changes are expertly managed and compensated by the flexible corrugated sheets of the oil tank, ensuring seamless operation. The fully sealed unit is perfectly isolated from external air, significantly mitigating oil degradation and insulation aging. This enhancement elevates operation reliability and reduces maintenance requirements during standard operation.
