Oil is used in Transformers to insulate and cool the windings.since heat reduces the efficiency of every electrical machine, oil is used in transformer for example to cool and maintain the efficiency level of the transformer .

∙ 10y agoOil has two functions: (1) to limit its temperature increase, and (2) to insulate those internal components that are at different potentials.
Because oil has a much greater specific heat capacity than air, it allows the transformer to supply greater loads without overheating than if it used air for cooling.
Because oil is a much better insulator than air, internal components at different potentials can be placed much closer together and this reduces the overall size and, therefore, the 'footprint' of the transformer, so it can occupy far less space.

What is the oil used in a transformers?
Transformer oil is a highly refined mineral oil.
Why desiel is used in transformers?
Transformers use transformer oil as an insulator and to conduct the heat away from the windings. The oil usually flows through a radiator in a closed circuit on high-power transformers.
Why grease is used in electrical transformers?
Grease is not used in transformers. An insulation oil is used to circulate around the internal coils to dissipate the heat generated when the transformer is in operation. Thermo syphon principals are used. Warm oil moves to the top of the transformer case and is displaced by cooler oil moving to the bottom creating a flow in the oil and there by aiding in the cooling of the coils. Transformers in larger sizes have cooling fins or tubes through which the oil flows to give more surface area to dissipate the internal coil heat. Smaller size transformers use the oil contact with the oil containment shell of the transformer to dissipate the heat.
What are the advantages of dry type over oil type transformers?
what are the major advantages of dry type transformers over oil type transformers
Is there need of transformer oil in all transformers?
No not really only some do :DAnswerFor transformers used in transmission and distribution systems, yes. Transformer oil is necessary for cooling and insulation purposes, enabling the 'footprint' of an oil-filled transformer to be smaller, and its rating to be higher, compared with those not filled with oil.
Was electric transformers filled with 1p2p oil?

Which oil is used in x ray machine for insulation and cooling?
Oil used in electric transformers.

Different types of insulation used for transformers?
Most transformers are insulated with polymers or porcelain. Some transformers have an oil based insulation which must be kept dry to remain effective.

How do oil cooled transformers without conservator work?
Oil filled transformers without a conservator are usually distribution transformers with relatively-low kV.A ratings. The volume of oil in these transformers is comparatively low and there is no need to allow for any substantial expansion, which is the main purpose of a conservator tank.
Definition working principles of oilfilled transformer?
Oil Filled Transformers Oil Filled Transformers are known for consistent performance even in harsh weather conditions like extreme temperature and atmospheric pollution. We follow oil impregnation procedure is used in the oil filling in these transformers. These are also known for low power loss, low noise and longer functional life. We have a vast array of Oil Filled Transformers for our clients that we manufacture as per the industry standards. In our range, clients can avail Amorphous Core Transformers, Converter Duty Transformers, Furnace Duty Transformers and Power Transformer. Besides, we also meet the demands of Distribution Transformers in Voltage ranges of 11 KV, 22 KV and 33 KV, Power Transformers upto 60 MVA in voltages of 11 KV, 22 KV, 33 KV, 66 KV & 132 KV and Isolation Transformers.
