What is an oil immersed transformer
In modern power systems, the oil immersed transformer stands as a cornerstone technology, enabling efficient and reliable transmission and distribution of electrical energy. As a type of power transformer, it utilizes insulating oil as both a cooling medium and an electrical insulator, distinguishing itself from dry-type transformers that rely on air or other gases. This dual functionality allows oil immersed transformers to handle higher power capacities, operate under harsher environmental conditions, and maintain long-term stability, making them indispensable in industrial, commercial, and utility applications.
