Transformers can be filled with various types of Refined Mineral Oil. That coefficient is something you would find in specifications of the supplier.
Commonly, it is .08% per degree Centigrade.

What is Coefficient of cubical expansion of heavy water?
The coefficient of thermal expansion depends on the temperature and pressure. It a pressure of 1 atmosphere the coefficient of thermal expansion are:at 4 deg C : –0.1321 at 20 deg C : 0.1212 at 50 deg C : 0.4280 at 100 deg C: 0.7454.
Is phenyl-2propanone in trasformer cooling oil?
Phenyl-2propanone, also known as P2P, is not typically found in transformer cooling oil. Transformer cooling oil usually consists of mineral oil or synthetic fluids designed to provide proper insulation and heat transfer properties for the transformer. P2P is a organic compound that is not commonly used in transformer applications.
What are the three physical properties that vary with temperature?
Three physical properties that vary with temperature are volume, density, and thermal expansion coefficient. As temperature increases, volume generally expands, which can lead to a decrease in density. The thermal expansion coefficient quantifies how much a material expands or contracts with changes in temperature.
Why should the coefficient of thermal expansion of a refractory metal be the lowest?
refractory metals have high melting points and are used in extremely hot environments; if expansion coefficient is lower this prevents high stresses that can develop due to thermal gradients during the high heat up. It helps to have high thermal conductivity as well
What term is given to the non expansion of material at high temperatures?
The term is "thermal expansion." When materials are heated, they typically expand due to increased molecular motion. Not expanding at high temperatures would suggest that the material has a low coefficient of thermal expansion.
What is the expansion coefficient of edible oil?
I think 0.000621
What is the thermal expansion coefficient for hydraulic oil?
The thermal expansion coefficient for hydraulic oil typically ranges from 0.0007 to 0.0008 per degree Celsius. This coefficient represents the change in volume of the hydraulic oil per unit change in temperature. It is important to consider when designing hydraulic systems to account for thermal expansion effects.
What is the relation between the coefficient of linear and superficial and volume expansion respectively?
The coefficient of linear expansion (α) is one-third of the coefficient of superficial expansion (β), and the coefficient of superficial expansion is one-third of the coefficient of volume expansion (γ). This relationship follows from the dimensional analysis of the expansion coefficients in the respective directions.
A material has a coefficient of volume expansion of 60×10^-6/degree celsius. What is its coefficient of expansion?
The coefficient of volume expansion is the triple of the linear expansion coefficient. So with a volume expansion coefficient of 60×10^-6/°C, the linear expansion coefficient would be 20×10^-6/°C.
What is the cubical coefficient of thermal expansion for metals?
Since most metals are isotropic, the cubical coefficient of expansion is three times the linear coefficient of expansion. The linear coefficient of expansion is obtained from measurement and tables for the specific material which are readily available.
Why liquids have two coefficient of expansion?
Liquids have two coefficients of expansion because they can expand in both volume (volume coefficient of expansion) and in area (area coefficient of expansion) when heated. The volume coefficient of expansion relates to changes in the volume of the liquid, while the area coefficient of expansion relates to changes in the surface area.
What material has the highest coefficient of thermal expansion?
The material with the highest coefficient of thermal expansion is typically graphite.
What is the coefficient of thermal expansion of air?
The coefficient of thermal expansion of air is approximately 0.00367 per degree Celsius.
What is oil transformer?
Transformer oil is pure insulating oil.
What is the relationship of coefficient linear expansion to actual expansion?
The coefficient of linear expansion is a constant value that quantifies how much a material expands per degree Celsius increase in temperature. The actual expansion of an object can be calculated by multiplying the coefficient of linear expansion by the original length of the object and the temperature change.
What is the coefficient of expansion of brass?
.000019
What is a binomial coefficient?
A binomial coefficient is a coefficient of any of the terms in the expansion of the binomial (x+y)^n.
