The insulating oil serves multiple crucial functions. Firstly, it provides electrical insulation, preventing short &#8211; circuits between the windings and the core. Secondly, it acts as a coolant, dissipating the heat generated during the operation of the transformer. This helps to maintain the temperature of the transformer within a safe range, ensuring its reliable and efficient performance. Oil &#8211; immersed transformers are widely used in power distribution networks, industrial plants, and various electrical systems due to their high capacity, long &#8211; term stability, and relatively low cost. <a href=\"https:\/\/www.nantongyawei.com\/structural-transformer\/oil-immersed-transformer\/\">Oil Immersed Transformer<\/a><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.nantongyawei.com\/uploads\/47635\/small\/step-up-power-transformer38d4b.jpg\"><\/p>\n<h2>1. <a href=\"https:\/\/www.nantongyawei.com\/\">Nantong Yawei New Energy Technology Co., Ltd.<\/a><\/h2>\n<h3>Company Introduction<\/h3>\n<p>Nantong Yawei New Energy Technology Co., Ltd. is a forward &#8211; looking enterprise that focuses on the research, development, production, and sales of new &#8211; energy &#8211; related electrical equipment, including high &#8211; quality oil &#8211; immersed transformers.
