“Dielectric material acts as a nonconductor to a direct electric current and is used to help ensure that an electro-static discharge does not accidentally set off the main charge of the weapon.”

As is well known, gases under ordinary conditions are nonconductors.

The hair furnishes protection against extreme and sudden variations of temperature by reason of the fact that hairs are poor conductors of heat, and inclose between them a still layer of air, itself a nonconductor.

Long before electricity was invented, human nature knew all about interposing nonconductors between itself and the truth.

It is a remarkably good nonconductor of electricity, and therefore it has been generally used to protect ocean cables, though recently rubber has been taking its place.
