Product Description
Oil immersed series transformer:
The S11-M series fully sealed oil immersed power transformer, proudly developed and produced by Chaotai Power, boasts exceptional performance with its low loss, low noise, and high efficiency attributes. This cutting-edge transformer delivers significant energy-saving benefits and substantially reduces environmental impact. Unlike conventional oil immersed transformers, this innovative design eliminates the need for an oil conservator.
