Placing a bushing on a new transformer

Dan moves a new bushing to a new transformer that was manufactured in: Where else? ~ China
This takes place at a switching station in Southern Nevada.
Transformer: A device used to transfer electric energy from one circuit to another, especially a pair of multiply wound, inductively coupled wire coils that effect such a transfer with a change in voltage, current, phase, or other electric characteristic.
Bushing: An insulating lining for an aperture through which a conductor passes.
Conductor: A substance or medium that conducts heat, light, sound, or especially an electric charge

500kv?

[1blujay]

525KV to 230KV

uhm...music just runs out there buddy...

i swear i saw him drop a spanner in the main tank ! sitting right on the winding !

Hi , You could try Googling Super high voltage / experimental high voltage cable / systems. Other than that Im not sure where you can read about this. Ill try and find out some info , possibly some websites / links ,etc. DC is starting to take off here in the UK ( where are you )? So called " light " DC systems are becoming popular especially in connection with wind-farm generation. They use plastic insulated ( PVC & XLPE ) cables up to 600KV DC ( although 200KV DC is more common here ).

is there a place where I can read more about this? My only experience is with cables between 33kV to 500kV (pex and oil-filled cables). But this was interesting. I have a little experience with DC cables, but I thought this was only long sub-sea cables.. We have a couple of those between Norway and Europe-mainland.

These very high voltage cables are plastic insulated but they are strictly experimental to date. Some of these super high voltage systems are DC. Anything over around 1300 / 1400 KV has to be underground ( or at least insulated cable) as this is around the voltage limit for open uninsulated conductors ( overhead lines)in air (although Sweden has an experimental 1500KV overhead line).Corona / leader formation means that this is the absolute limit possible for open overhead line conductors in air.

@TheLowey08

alright. thank you. i'll be in sweden this autumn to install 220kV undergroundcables.. Did not know that it was possible with that high voltage in undergroundcables. How are they insulated and who manufactures this kind of cable?

[TheLowey08]

Hi , higest voltage transmission line currently in everyday use is 1150 KV in Russia on the trans-Siberian power line. There are 1500KV and 2200KV ( the latter is underground cable ) in Sweden and Italy repectively but these are experimental only , for assesing materials , switchgear , transformers , etc , at very high voltages , and not " everyday " power lines.

a chinese transformer? ... im sure theres lead in the paint and it'll blow after a week.

[soundseeker63]

That is for WAY mor than 132 kv lol!!! 132 Kv insulators are roughly as tall is I am (5'8) Id say they are 500 or 525kv bushes.
