Product Description
Oil Immersed Series Transformer:
Introducing the S11-M Series Fully Sealed Oil Immersed Power Transformer by Chaotai Power, engineered with precision to deliver outstanding performance. This transformer stands out with its remarkable features: low loss, low noise, and high efficiency. These attributes ensure significant energy savings and a notable reduction in environmental impact. Unlike traditional transformers, this innovative model eliminates the need for an oil conservator. The adaptable corrugated oil tank automatically adjusts the oil volume through its elastic corrugated sheet, ensuring seamless operation. By being hermetically sealed from the atmosphere, it protects against oil degradation and insulation aging, significantly boosting reliability and minimizing the need for maintenance during regular operation.
