Zenith Computer's ,thanks to made you this machine.I'm very proud of you.sir can i ask about I core? how many pieces I core you use it or many layer at.....I'm from Philippines.thanks.....

Thank you

40mm*50mm*100mm

Kiska coil lagaia aluminium or copper please reply me.

How deferent ampear aluminium and copper coil?

Thank you

@@zenithcomputers3286Sir- are you also selling this transformer i need 200A transformer ? You may reply at my whatsapp no 9380879567

Typically.whats the name of winding of transformer?

@@zenithcomputers3286 yea,I know it insulating varnish. But please what I want to,is the name of the Product. Thank you.

@@zenithcomputers3286 Ok . Thank you.

Yess I doo

Cooper is better...

did not think of that!!!!

How can i order sir...

Growley M pls consider i am not literate of electrical matters but may i ask what is this lacquer?

It is sort of a varnish. It provides a thin layer of electrical insulation. It prevents electrical current from circulating in the core, but allows magnetic flux to circulate. The electrical eddy currents waste energy, as heat, and in worse case scenarios will cause the transformer to overheat and melt insulation. I am sure that there is an industry accepted type or formulation of lacquer for transformer or motor or generator core laminations but you could experiment with different types of shellac or varnish, maybe. Possibly you might find an inexpensive substitute that would work okay. The very reason why transformer cores are made from laminations is so you can prevent or confine these eddy currents, so it makes sense to insulate them from one another. The insulation should be very thin, of course. Kapton tape might even work. Paper? Maybe. Anyway the ends and edges as well as the surfaces should be insulated as well. As you have seen, it will work with no insulation, but it would without a doubt work better with an insulation coating on the lamination pieces, running cooler and more efficiently. If you tear apart most commercial transformers you will see that there is a layer of lacquer on the laminations. Also often the wire is coated with lacquer and has no cotton, fiberglass, PVC, etc insulation. You can verify that this thin coating actually does insulate, with an ohmmeter or multimeter. One advantage of lacquer insulated transformer wire is that the copper coils can be wound more compactly. It could break down, electrically, at very high voltages which is why many old tube type television transformers had secondary wire insulated with silk, cotton, or other fiber. The various vacuum tubes and especially the picture tube required high voltages that could arc through ordinary enamel coating on the transformer windings. For a welder, you are actually stepping down the voltage, and so enameled wire, also called magnet wire, might work quite well, if you have a source for heavy enough wire and can form it into coils.

I only have one question, what kind of rolled steel I can use, where I live does not sell to silica, please help.

You really think it's necessary to further insulate insulated wire? I can understand doing so with magnet wire which has such thin insulation, but that insulated wire should be plenty well insulated as-is. I can't imagine lacquer does much more. Though on the other hand, adding some sort of coil dope (personally, I've not found anything better than good old fashioned xylene and styrofoam) to fill the gaps between the wires to reduce the noise

@@growleym504 Please Sir, Can I use the lacquer for Coating Copper wire's; Will also withstand High Heat? Please help me. Thank you Sir.

En serie para 220v. y en paralelo para 110 v. El secundario siempre en serie.

Hola...las bobinas primarias se conectan,en serie (220v.); en paralelo (110v.).El secundario solo trabaja en serie.No hay otras derivaciones pero puedes hacerlas en una de las bobinas... aunque no creo que logres variar en mucho el amperaje.Suerte.
