Product Description
Oil Immersed Series Transformer:
The S11-M series fully sealed oil immersed power transformer, proudly crafted by Chaotai Power, stands as a beacon of innovation with its commendable attributes of minimal loss, serene operation, and heightened efficiency. This marvel not only champions energy conservation but also significantly curtails environmental contamination. Elevating above the conventional oil-immersed counterparts, this transformer ingeniously omits the oil conservator. It intelligently manages oil volume fluctuations through the resilient corrugated sheets of its oil tank, ensuring a seamless adjustment. Safeguarded from atmospheric exposure, it expertly retards oil degradation and insulation wear, thereby enhancing operational dependability and negating the need for maintenance during standard operations.
