All atoms have electrons that orbit the nucleus, we are concerned with the outermost orbit. The outer orbit shell can have from 1 to 8 electrons. The fewer electrons an atom has in this orbit the better it is at conduction (one or two electrons, it is easy to knock one of the electrons out of orbit and pass to the next atom). The more electrons you have, the better it is at insulating. Nothing is a perfect insulator, if you apply enough voltage the electrons will move (current will flow). This is why the insulation on conductors have a voltage rating.
Yes.
A copper pipe would work as a conductor because most metals like copper, they are well conductors. If you want to know an example of an insulator, you can say rubber is a good insulator.
It is an insulator.
Insulator strings are normally used for high tension wires. They work as the main insulators for wires and assure a smooth connection between the conductors and the poles.

He's an insulator. I work with him.
the same way an insulator and a conductor will work with out the electron theory!
Rubber is an insulator for normal voltages.
