Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series, a masterpiece of engineering in the realm of fully sealed oil-immersed transformers, meticulously crafted by Zhejiang Chaotai Complete Equipment Co., Ltd. This outstanding transformer is distinguished by its unparalleled attributes: from unprecedented low energy loss to whisper-quiet operation, all while maintaining top-tier efficiency. As a beacon of eco-friendly technology, it dramatically diminishes environmental pollution. Departing from traditional designs, this state-of-the-art model requires no oil conservator, thanks to its ingenious design that leverages the elasticity of the corrugated oil tank to autonomously regulate and accommodate oil volume fluctuations. This ensures the transformer is hermetically sealed from atmospheric exposure, safeguarding against oil degradation and insulation aging. The result is a significant boost in operational reliability and a maintenance-free experience during normal operations.
