Definition of "Insulator" |
A non-conductor of electricity (or heat). / Material of such low conductivity that the flow of current through it can usually be neglected. A device having high electrical resistance; used for supporting or separating conductors so as to prevent undesired flow of current from the conductors to other objects. Glass or ceramic materials are commonly used insulators. / A device that is used to electrically isolate a conductor or electrical device from ground or a different electrical potential. Electrical insulators are manufactured by Porcelain Products Company and W.H. Salisbury & Company. / (1) a device designed to separate and prevent the flow of current between conductors. Properties of the dielectric (insulating) material and geometry of the insulator determine maximum voltage and temperature ratings. |
