How long's a piece of string? It obviously depends on how big the transformer is!
to cool a winding of transformer and it is a insulating material and transformer oil is a purifing oil
Significantly-better cooling and insulation than air. This means that the transformer can operate at higher power ratings than an equivalent air-cooled transformer, and its internal electrical components can be much closer together, giving an oil transformer a much smaller footprint so it takes up far less space in a substation.

When the water content in the oil in the Oil rises up to or more than 2% than it is needed to replace the transformer oil or filter it.

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.
That depends on the model of the transformer. I have seen transformers that required 7500 liters and some that needed 2,5 liters.
Transformer oil is pure insulating oil.

An oil transformer is filled with PCB oil to better transfer heat from the windings to the outside case (and into the air).
