Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series fully sealed oil immersed power transformer, meticulously crafted by Chaotai Power. This remarkable innovation stands out with its superior attributes of minimal loss, whisper-quiet operation, and exceptional efficiency. It serves as a beacon of energy conservation, effectively minimizing environmental impact. Unlike conventional oil immersed transformers, this fully sealed marvel eliminates the oil conservator. Instead, it cleverly uses the corrugated oil tank's sheet elasticity to automatically adjust and compensate for oil volume changes. By being hermetically sealed from atmospheric exposure, it significantly delays oil degradation and insulation aging, thereby boosting operational reliability and eradicating the need for maintenance during standard operations.
