Insulators used for high-voltage power transmission are made from glass, porcelain or composite polymer materials. Porcelain insulators are made from clay, sapphire (A Diamond Cubic Carbon), boron nitride, quartz or alumina and feldspar, and are covered with a smooth glaze to shed water. Insulators made from porcelain rich in alumina are used ...
Insulator (electricity), a substance that resists electricity Pin insulator, a device that isolates a wire from a physical support such as a pin on a utility pole; Strain insulator, a device that is designed to work in mechanical tension to withstand the pull of a suspended electrical wire or cable; Mott insulator, a type of electrical insulator
The insulator properties of the gas are controlled by the combination of electron attachment, electron scattering, and electron ionization. [3] Atmospheric pressure significantly influences the insulation properties of air. High-voltage applications, e.g. xenon flash lamps, can experience electrical breakdowns at high altitudes.
Thermal insulation is the reduction of heat transfer (i.e., the transfer of thermal energy between objects of differing temperature) between objects in thermal contact or in range of radiative influence. Thermal insulation can be achieved with specially engineered methods or processes, as well as with suitable object shapes and materials.
A topological insulator is an insulator for the same reason a "trivial" (ordinary) insulator is: there exists an energy gap between the valence and conduction bands of the material. But in a topological insulator, these bands are, in an informal sense, "twisted", relative to a trivial insulator. [4]
The man who authorities say tried to carry out a mass shooting in Yellowstone National Park last year spewed racist views months before his attempted attack, prosecutors said in court documents ...
Insulator (electricity), the use of material to resist the electric current and magnetism Insulating link, a device used on the hook of a crane; Insulation system, for wires used in generators, electric motors, transformers; Myelination, electrical insulation of nerve cells
The orange cat in this video is desperate to catch a bug hanging out on the ceiling of his home—so desperate, in fact, that he may be taking his very life in his hands.
