    • n insulator One who or that which insulates; specifically, a substance or body that interrupts the communication of electricity or heat to surrounding objects; a non-conductor; anything through which an electric current will not pass. The figures show the usual forms of insulators employed in telegraph-lines to support the wire on the post. They are frequently made of porcelain or glass, and in the shape of an inverted cup, round which the wire is wrapped or is attached by a hook depending from it, or the like. In the case of electricity the commonest insulators for supports are glass, porcelain, and vulcanized rubber; and for covering wires conveying currents, silk, cotton, gutta-percha, and rubber. These substances do not absolutely prevent the communication of electricity, but a good glass Leyden jar, for example, will hold a charge for months. No perfect insulator for either electricity or heat is known, and the distinction between conductors and insulators is some what arbitrary.
