The only time I ever heard the word "Insultator" was in an episode of Beyond Belief: Fact or Fiction. In this episode, the Insultator is an electronic device a taxi driver installs in his cab that plays insults about people being "cheap" to passengers who don't tip, e.g., "Nice tip, you must be saving your money for a facelift."
I Googled it and also discovered that it now appears to be a French app on iTunes that generates insults.
Bizarre!
Insultator
because you need it for insultator in the body during cold weather
An insulator is a material that does not conduct heat or electricity well, preventing the flow of energy. Examples include rubber, plastic, and glass for electrical insulation, and materials like wood, fiberglass, and foam for thermal insulation.
It is an electrical conductor, because it is made of iron. Iron, like all metals, contains "free" or "conduction" electrons which can move through the metal and carry charge. Iron is also a thermal conductor, for the same reason.
A conductor is a material that allows electric current to flow through it easily, such as metals. An insulator is a material that does not allow electric current to flow through it easily, such as rubber or glass. Conductors have free-moving electrons, while insulators have tightly bound electrons.
