Product Description
Oil Immersed Series Transformer:
The S11-M series is a fully sealed oil immersed power transformer, meticulously crafted by Chaotai Power. It stands out with its remarkable advantages: reduced energy loss, whisper-quiet operation, and outstanding efficiency. This cutting-edge transformer is designed to deliver excellent energy-saving performance and to minimize environmental impact. Unlike conventional oil immersed transformers, the fully sealed design does away with the oil conservator. Instead, it leverages the elasticity of the corrugated oil tank to automatically adjust and compensate for changes in oil volume. This innovation ensures the transformer is hermetically sealed from the air, effectively slowing oil degradation and insulation aging, enhancing operational reliability, and eliminating the need for maintenance during standard operations.
