Product Description
Oil Immersed Series Transformer:
The S11-M series fully sealed oil immersed power transformer, meticulously engineered and manufactured by Zhejiang Chaotai Complete Equipment Co., Ltd., is a marvel in modern energy management solutions. Featuring low loss, minimal noise, and exceptional efficiency, this transformer significantly enhances energy savings and reduces environmental impact. In comparison to traditional oil immersed transformers, our advanced fully sealed model ingeniously eliminates the oil conservator. Instead, it offers automatic oil volume adjustment and compensation through the innovative elastic corrugated sheets of its oil tank. By isolating the transformer from ambient air, we effectively shield it from oil deterioration and insulation aging, thereby boosting operational reliability and ensuring maintenance-free performance during regular operations.
