Introduction
An oil-immersed transformer is a transformer device that uses oil cooling to reduce the temperature of a transformer. The body of the oil-immersed transformer is installed in a welded steel tank filled with insulating oil. When an oil-immersed transformer is running, the heat from the coil and core is first transferred to the insulating oil and then to the cooling medium. The power range is 6-35kV, which can be divided into immersion free cooling transformers and immersion forced air cooling transformers according to the size of the capacity.
 
 
A transformer is a device that uses the principle of electromagnetic induction to change the alternating voltage, and the main components are the primary coil, the secondary coil and the core (magnetic core). In electrical equipment and wireless circuits, it is often used as rising and falling voltage, matching impedance, safety isolation, etc.
