Cooling; also the oil will prevent arcing since it has a higher dielectric strength than air.
---------------------------------------------------------------------------------------------------
Actually, there are no moving contacts in a transformer, so (normally) no arcing should occur.
The oil cools the windings by carrying heat generated via current flow away from the windings. The oil is moved either by natural thermo-siphon (the upward movement of a higher temperature substance and downward movement of a cooler substance), or by forced circulation, through cooling fins located on the outside of the transformer shell, where either ambient air or forced air (fans) remove the heat.
Additionally, the oil forms a moisture barrier between the transformer windings and the outside air, preventing insulation breakdown and the potential for primary-to-secondary or turn-to-turn shorts.

What is the purpose of the oil in a oil filled transformer?
cooling Not only that, but also to protect the windings from moisture.
What purpose of oil filter in transformer?
To remove impurity particles which could reduce the insulation property of the oil as well as that of the windings.
What is oil transformer?
Transformer oil is pure insulating oil.
What is the present excise duty of transformer oil?
to cool a winding of transformer and it is a insulating material and transformer oil is a purifing oil
What type of oil transformer is nytro Libra oil?
Nytro libra is an uninhibited transformer oil
What is difference between interposing voltage transformer and potential transformer?
potential transformer is to maser and protection purpose the ivt is used for synchronicing purpose
Name of transformer oil?
An oil transformer is filled with PCB oil to better transfer heat from the windings to the outside case (and into the air).
How does conservator work in transformer?
To allow room for oil expansion and contraction. The transformer is completely filled with the oil and when it heats up under load or due to ambient temperatures, the oil has to have a place to go. In the event of colder weather or if the transformer is not under heavy load the oil cools and contracts creating a slight vacuum inside the tank. The conservator acts as a reservoir of oil that can then flow back into the tank so that no air enters it.
What is means of transformer oil what contents is there in that oil?
transformer consists of polychlorinated biphenyls,...etc
What is insulation in transformer?
Depending on the size of the transformer, several different types of insulator are used. These include varnishes, plastics, paper, and fabrics (to insulate the windings), wood (spacers), and oil. Transformer oil improves the insulation value of paper, fabrics, and wood when absorbed by them. The oil has a secondary purpose, which is to cool the transformer.
WHAT will happen if you run oil transformer with out oil?
As well as providing a cooling medium, transformer oil is also used to insulate a transformer. As its dielectric strength (how well it insulates) is much higher than air, it means that components within a transformer that are at different potentials can be placed much closer together if they are immersed in oil. So, operating an oil-filled transformer without oil will likely cause insulation breakdown within the transformer.
How the transformer oil is circulated and how it works in the transformer?
convection currents
