Presumably, you are asking "What is the function of transformer laminations?", rather than their "uses".
A transformer's magnetic circuit, or core, is made from thin sheets of silicon steel, each insulated from each other, and termed laminations.
The alternating current flowing through a transformer's primary winding not only induces a voltage into the secondary windings, but into the core itself, resulting in circulating currents, called eddy currents, which result in energy losses. The very low cross-sectional area of each lamination acts to offer a high resistance to the flow of these eddy currents, thus minimising these currents, and the associated eddy-current losses.

How do you preserve a spare power transformer?
Small electrical transformers typically are stored in a cool, dry environment to reduce insulation deterioration. Large transformers are typically stored in a similar way, however they are usually only stored for short periods are demand for large transformers is very high and power companies usually find uses for them rapidly.
What is transformers job?
It depends on the type of transformer:transmission/distribution transformers step up or step down system voltagesisolation transformers electrically isolate two systems without affecting their voltagesmatching transformers are used in electronic circuits for impedance matchinginstrument transformers step down voltages (voltage transformers) or currents (current transformers) for measurement or protection applications
What are at least 2 types of electrical transformers in science?
A variety of electrical transformers are produced for a variety of purposes. All of the types use the same principle discovered by Michael Faraday, and employ many of the same parts. The various types include. Audio transformers, Instrument transformers, Pulse transformers, Power transformers, RF transformers. .
Do shale and mudstone have the same appearance?
Very similar, yes, but without the lamination that shale exhibits.
Are Malibu low voltage transformers AC or DC?
All transformers are a.c. machines.
Why pet film used for lamination?
its good for lamination
What are cold lamination machines?
Cold lamination machines offer an alternative method of lamination by using adhesives instead of heat. As opposed to traditional thermal machines, cold lamination machines are significantly less expensive and will not damage materials vulnerable to heat.
Uses of transformer?
transformers are used to step up or step down the voltages
Who voices Bumblebee in Transformers 2 Revenge of the Fallen?

Does Galvatron turn back into Megatron in Transformers G1?

What websites sell laminator pouches?
A laminating pouch is a lamination-plastic sleeve that a sheet of paper or other thin object can be inserted in, to allow easy lamination using a home lamination machine. Amazon sells laminating pouches, as does a site called Lamination Depot.
How do you defeat bumblebee on transformers?

Is there a cover you can put over your laptop screen so it is not so bright and not such a strain on your eyes?
You can use a tinted lamination from any place where they stick lamination on windscreens in automobiles who use dry lamination.
What do you call gluing wood pieces parallel to each other?
Lamination is the gluing together of sheets of wood .
What is theMethod of lamination for flexible packaging?
Dear friend , The techniques used for lamination can be classified on the basis of adhesive system used. The most common lamination techniques are · Wet lamination - By using water based adhesives · Dry lamination - By using solvent based or solventless adhesives · Hot melt or wax lamination - By using wax or polymers like polyethylene, polyamides etc. · Extrusion lamination - By extruding polymers between two substrates In packaging industry, solvent-based & solvent free adhesives are commonly used for most of the flexible laminates .

How much is the 2004 Iowa statehood quarter with a lamination error worth?
State quarter lamination errors retail for about $10.
Why does one hear a hum when standing near a power tranformer?
Why do transformers hum?We could use the tired saying 'because they don't know the words,' but that might get us sidetracked.The short and simple answer is that transformers hum because of an effect known as 'lamination rattle' caused by DC voltage on the line or poor construction or both. 'Lam' rattle occurs in all transformers to some degree, that degree being related to the quality of the transformer and the quality of the line voltage.
