An insulating (non-conducting) material.
Nonconductive. Fibre optic cables may be constructed using all dielectric materials. These cables are especially suitable for use in high EMI environments and areas of high electrical potential.
Substance that is a poor conductor of electricity and will sustain the force of an electric field passing through it. Also called an insulator.
Non-metallic. All-dielectric cables are nonconductive, contain no metal & are lightning resistant.
A medium through which electric attraction or repulsion may be sustained - an insulator.
Non-metallic and therefore, non-conductive. Glass fibers are considered dielectric. A dielectric cable contains no metallic components.
A material that does not conduct electrical current through its matrix body. However, most of these materials will give up or add surface electrons easily when an incentive presents itself. Thus, significant static charge can occur on a dielectric material, especially one that is running over rolls in a coating and drying process.
material is a substance that is a poor conductor of electricity, but an efficient supporter of electrostatic fields.
An insulating material, or a material that can sustain an electric field with very little dissipation of power.
Usually Teflon, polyethylene or other plastics that acts as insulators and encapsulate signal-carrying conductors.
A material having low electrical conductivity compared to that of metal.
Insulating materials exposed to electric fields are called dielectrics. Dielectrics are necessary parts in the construction of any cable because they prevent oxidation and keep the conductors from touching one another. In audio cables, relatively low voltage and current levels mean that dielectric strength is not the most important factor. Far more significant in its effect on the sound is a material's dielectric absorption. This characteristic describes the way a dielectric may discharge a secondary signal into the conductor out of phase with the audio signal. As a current is passed through a conductor, an electromagnetic field is created which interacts with the dielectric material and temporarily displaces the molecular structure. If the dielectric material has good elasticity and can return quickly to its normal state, then the material is said to have low dielectric hysteresis or loss and will have little audible effect on the signal.
The insulating part of a capacitor. In small examples it may be mica or paraffin waxed paper. In larger it may be oil or air.
Material that does not conduct electricity readily, i.e., an insulator. A good dielectric should also have other properties: It must resist breakdown under high voltages; it should not itself draw appreciable power from the circuit; it must have reasonable physical stability; and none of its characteristics should vary much over a fairly wide temperature range. One important application of dielectrics is as the material separating the plates of a capacitor.
a non-conductive material used to separate conductive wires. Typically used to describe the material used to fill the space between the center conductor and the shield on coaxial wire.

Fiber optic cable does not need insulation, but usually has it anyway for protection. Recent research has indicated that low insulation value shielding may actually be preferred to high insulation value in high quality copper communications cables to minimize electro-static problems.

More or less a synonym for electrical insulator, a material with a low (compared with that of a metal) electrical conductivity. The term insulator is more precise given that at some frequencies the relative permittivity (or dielectric function) of a material usually described as an insulator may have values thought to be characteristic of metals, and at other frequencies the relative permittivity of a metal may have values thought to be characteristic of a dielectric (insulator).
