It is mineral oil nafta or parafin based.
An oil filled transformer is usually used outdoors and a dry core transformer is usually used indoors.
Mineral oil
it is a pit which is used to drain leakage oil of transformers .AnswerIt's a walled area, surrounding a transformer, intended to contain any oil leakage from a transformer.
The oil level indicator in a transformer is used to show the oil level.
Transformer oil is a highly refined mineral oil.
Mineral oil
Transformer oil is pure insulating 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.
to cool a winding of transformer and it is a insulating material and transformer oil is a purifing oil
Oil or similar is used as a cooling fluid in electrical transformer, because it is electrically insulating - which water is not. The figure of merit is the lack of conductivity.
Oil is used to cool the transformer. There is no telling what the transformer in question uses without knowing the specific part number and looking up the specification.
Nytro libra is an uninhibited transformer oil
