Product Description
Oil Immersed Series Transformer:
The S11-M series fully sealed oil-immersed power transformer, masterfully developed by Chaotai Power, stands as a testament to engineering excellence with its impressive features of low loss, minimal noise, and unmatched efficiency. This transformer not only performs brilliantly in terms of energy conservation but also substantially curtails environmental pollution. Unlike conventional oil-immersed transformers, this innovative design eliminates the oil conservator. The adaptive oil volume adjustment is facilitated by the corrugated oil tank's elasticity, ensuring the transformer remains sealed from any air exposure. This ingenious design prevents oil degradation and insulation aging, thereby significantly enhancing reliability and ensuring a maintenance-free operation over its standard lifecycle.
