High Voltage Three-Phase Oil-Immersed Power Transformer by Linmai, Fixed Type

Introducing the cutting-edge S11-M series fully sealed oil-immersed power transformers, meticulously crafted by Chaotai Power. These transformers boast exceptional features such as minimal energy loss, whisper-quiet operation, and outstanding efficiency, providing a substantial energy-saving solution and minimizing environmental impact. Unlike traditional oil-immersed transformers, the fully sealed variant eliminates the need for an oil conservator. Instead, it ingeniously adapts to oil volume changes with the flexible corrugated sheet of the corrugated oil tank. This innovative design ensures the transformer remains isolated from air exposure, significantly reducing the risk of oil degradation and insulation aging, thereby enhancing operational reliability and negating the need for maintenance during regular operation.
