insulator

[′in·sə‚lād·ər]
(electricity)
A device having high electrical resistance and used for supporting or separating conductors to prevent undesired flow of current from them to other objects. Also known as electrical insulator.
(materials)
A material that is a poor conductor of heat, sound, or electricity.
(solid-state physics)
A substance in which the normal energy band is full and is separated from the first excitation band by a forbidden band that can be penetrated only by an electron having an energy of several electronvolts, sufficient to disrupt the substance.

electrical insulator

A component or device made from material having great enough resistance to the flow of electric current to be effectively considered as a nonconductor of current.

insulator

A material that does not conduct electricity. Contrast with conductor.
