Most Transformers are insulated with polymers or porcelain. Some transformers have an oil based insulation which must be kept dry to remain effective.

Which types of transformers used in industries?
There are many different types of transformers used in industry. They include polyphase, capacitor voltage, and resonant transformers.
Why high voltage transformers have graded insulation?
It is to decrease the amt of insullation materials used. It can be used only for star connection.Answer'Graded insulation' is all about controlling the shape of the electric field within the insulator to prevent breakdown due to local peaks in potential difference across that insulation.
What are electrical sleeves used for?
In the electrical industry there are many different types of sleeves used. There are insulation sleeves, linesman's high voltage sleeves and conduit sleeves to name a few. The insulation sleeve is used for the protection of electrical conductors. Linesman's sleeves are used for extensions to the protective rubber gauntlets that they wear when working on high tension wiring systems. Conduit sleeves are used when a broken conduit needs to be repaired in situ.
High AC voltages are usually measured with?
They are usually measured using potential transformers that lower the voltages so that normal metering equipment can be used. Potential transformers PT's are almost no different that regular transformers except they are designed to be extremely accurate since they are used for metering purposes.
What are the advantages of power transformers over voltage transformers?
Power transformers can be used for power transformation. Voltage transformers are not suitable for high power applications.

What are three different product I could use for soundproofing my bedroom?
Different types of insulation are used for soundproofing. Felt insulation, acoustic foam insulation and mineral fiber are the most common types.
Which oil is used in x ray machine for insulation and cooling?
Oil used in electric transformers.
What types of insulation can be used to insulate a house?
There are many types of insulation that can be used to insulate a house. There is fiberglass, mineral, plastic fibers, and natural fibers insulation.There is also insulation boards.

What types of transformers are used in an x-ray machine?
Auto bots.
Where you used the oil type transformer?
we always used them when there is a major step in amperage and it generates a bit of heat. The oilbath transformers (such as the ones you see on the pole) can reduce or increase the amperage in the line so that it is no longer a distribution level, but instead one that is safe for home electronics and appliances.AnswerAll transmission and distribution transformers are oil-immersed types. This is to improve their insulation, allowing them to be made more compact and occupying a smaller 'footprint', and to enable them to be kept cool. So the answer is oil is used for insulation and cooling.
Why is class A winding insulation is only used in oil filled transformers?
This is because the oil has flash over point at 140 deg.Cl and the winding insulation cannot exceed the flash point of the oil.
What model of phone was in the transformers movie?
To find out the type of phones in the move "Transformers" you would have to watch the movie carefully and identify the types of phones used.
What is the two types of transformer commonly used in industry?
Step-up and Step-down transformers
What is a type of insulation?
There is more than one kind of insulation, the main types being thermal and electrical. Fiber glass is commonly used for thermal insulation, and rubber is a good electrical insulator.
What is a transformer oil analysis looking for?
Stuff that shouldn't be in the oil - depending on what has happened to the transformer, different particulates will be found. Gasing, internal arcing, insulation degredation, etc. will have different "fingerprints", or patterns of molecules in the oil. Oil analysis can be used to identify transformers that are at risk of failure in the near future.
