The insulating oil serves multiple crucial functions. Firstly, it provides electrical insulation, preventing short &#8211; circuits between different parts of the transformer. Secondly, it acts as a coolant, carrying away the heat generated during the operation of the transformer, ensuring its stable performance and long &#8211; term reliability. Oil &#8211; immersed transformers are widely used in power systems, from large &#8211; scale power generation plants to distribution networks, due to their high efficiency, good insulation properties, and relatively long service life. <a href=\"https:\/\/www.deyunelectric.com\/transformer\/oil-immersed-transformer\/\">Oil Immersed Transformer<\/a><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.deyunelectric.com\/uploads\/202543378\/small\/24kv-outdoor-vacuum-circuit-breaker2f3795f5-d592-4ed3-ba4c-acf8cab187db.jpg\"><\/p>\n<h2>1. <a href=\"https:\/\/www.deyunelectric.com\/\">Deepwill International Technology Development (Jiangsu) Co., Ltd.<\/a><\/h2>\n<h3>Company Introduction<\/h3>\n<p>Deepwill International Technology Development (Jiangsu) Co., Ltd. is a leading player in the field of electrical equipment manufacturing.
