what is a liquid electrical insulator?

Question

its for my homework i need to describe the properties and a typical application of a liquid electricl insulator

Plz help !!!!!!

i have to use as much detail as possiable !

Answer 1

A liquid insulator is typically also used as a coolant.

Liquid insulators are used in very high power, high current devices, where using solid insulation and a heat sink would be too bulky, or where a very large amount of waste heat has to be removed from a relatively small area.

Distilled water is a good insulator and an excellent coolant, provided you can keep the water free of even small amounts of impurities.

More commonly silicone oil is used, since it doesn't need to be especially pure, and is much less likely to cause corrosion. The major drawback here is that oil is not as good of a coolant as water. Silicone oils are also not very environmentally friendly.

Typical applications include large DC inverters, high power transistors and switching diodes, and compact high current transformers.

Hope that makes sense,

Solid, ceramic materials, glass. Properties solid and an insulator. Uses supporting high voltage power lines on electricity pylons. Liquid oil. Properties a liquid and an insulator. Uses in cooling transformers. Gas Sulphur hexafluoride. Properties a gas and an insulator. Uses in electrical switch gear to prevent arcing.

Answer 4

Pure water doesn't conduct well. There are plenty of oils, I'm sure, that conduct poorly.

Oh, well in that case, why don't we just write your homework for you. How many words do you need? We'd better hurry. You can't turn it in in our handwriting. ;)

Answer 5

water that has all salt's and minerals removed from it will not conduct electricity.
