Translationsinsulator
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 insulatorA 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.insulatorA material that does not conduct electricity.
