[terry the tiler]

Someone on site said "its full of sand, undo it and tip it out?" You need to undo the top half of his head and tip a brain in.

My biggest one is 5kva, now that is heavy.

[Dave]

The weight comes from the Tar insulation as neale said.. then you have the weight of the transformer itself..

my transformer turns into a car then i just drive it to the job

They used to be a lot heavier.

All mine are 3KVAs one of them is really noisy, and was told when it's on to hit the side with a big hammer to stop plates inside from vibrating just haven't had the bottle to try it.

Was it the same guy that thinks they are full of sand?


Dont hit it, get it checked by an electrician or buy a new one.

mine are also 3KVAs and are 18kgs !!!! its ridiculous. you can get a light weight transformer around 10 kgs i think but its almost double in price.

I knew it was your mate Tel, just wondered if he got around a bit, as in going to Kent.

At a guess i would say that it needs to be earthed ,never gave it much thought before.Although my back has screamed out a few times

The link merle gave is for a totally diffrent thing,more like an industrial generator

What a guy....I tried searching for the same thing and all I got was stuff on bleedin' robots! Didn't even say what voltage they worked on.

[Dave]

I smashed one open as a lad.. it had black tar like base..

1st job for the apprentice get the transformer then make a brew

[cooperrmb]

Your transformers are called isolation transformers the input voltage is 230v and output is 110 v. There is a primary and secondary winding which is copper wire they are isolated from each other and the voltage is developed with the magnetic field. The copper windings are wrapped around an iron core which is very heavy. Larger transformers for hotels eg weigh several tonnes.

Some of them are full of concrete.........




At least the one that a mate of mine bought at a car boot sale was
