Product Description
Oil Immersed Series Transformer:
The S11-M series fully sealed oil immersed power transformer, innovatively developed and crafted by Chaotai Power, stands out with its exceptional advantages of minimized loss, reduced noise, and maximized efficiency. This cutting-edge transformer not only ensures an outstanding energy-saving performance but also actively contributes to pollution reduction. Unlike conventional oil-immersed transformers, our fully sealed design eliminates the need for an oil conservator, where fluctuations in oil volume are seamlessly managed by the corrugated oil tank's elasticity. This strategic isolation from air effectively curtails oil degradation and insulation aging, significantly boosting operational reliability while eliminating the need for maintenance during normal operations.
