Insulators are made of non conductive materials and that is the point. Insulators are used to prevent electrical current from leaving the circuit being utilized.
"insulators"
Any material that electricity can't pass through is classed as an insulator. Examples of insulators are glass, ceramics, plastic, dry wood, and so on.
Note that "electricity" doesn't flow, only current does, which is one aspect of electricity, does. Current is the flow of electrons. The main materials that do not allow the easy flow of electrons are rubber, nylon wood, glass, ceramic, plastic and free air.
The current cannot pass through the oils.Oils are moleculer so molecules cannot conduct electric current

There are types of aluminum and carbon crystals that can be seen through. Then there is meta-materials, like invisibility cloaks, but they are beyond our current technology.

insulators
First of all, because that's the definition of an insulator - a substance that doesn't easily let current pass. As to the mechanism, that has to do with how freely the charge carriers (usually electrons) can move.
Yes.
