Определение insulator в Английский Язык Английский Язык словарь
100px|right|insulator A non-conductive structure, coating or device that does not transmit sound, heat or electricity (see image)
To isolate electrical wires from the pylons supporting them, one often uses glass insulators.
A substance that does not transmit heat (thermal insulator), sound (acoustic insulator) or electricity (electrical insulator)
insulators resist the flow of electricity Insulating materials are used to coat copper conducting wires and are used to make electrical work gloves Insulators help to protect humans from coming into contact with electricity flowing through conductors
An insulator is a material that insulates something. Fat is an excellent insulator against the cold. a material or object which does not allow electricity, heat, or sound to pass through it conductor. Substance that blocks or retards the flow of electric current or heat. An insulator is a poor conductor because it has a high resistance to such flow. Electrical insulators are commonly used to hold conductors in place, separating them from one another and from surrounding structures to form a barrier between energized parts of an electric circuit and confine the flow of current to wires or other conducting paths. Electrical insulators include rubber, plastic, porcelain, and mica. Thermal insulators. which break up the heat-flow path by absorbing radiant heat, include fiberglass, cork, and rock wool
A material that is a poor conductor of electricity or heat, and used to separate conductors from one another or to protect personnel from active electrical devices Examples: silicon dioxide (glass), silicon nitride, rubber, ceramics, wood
An insulator is a material that electricity has a hard time moving through, if it can at all For a true insulator it takes a very high voltage to produce any current at all, and that often results in damage to the insulator The opposite of a conductor
Any material that will not conduct electricity, such as rubber Used on poles to carry wire and insulates the conductor from the ground
A material that is a poor conductor of electricity - used to separate conductors from one another or to protect personnel from electricity
a nonmetallic material that has a filled valence band at 0 K and a relatively wide energy band gap; consequently the room-temperature electrical conductivity is very low
A material which will not conduct electricity Insulators can often tribocharge to very high levels since a charge will remain stationary, or static, on its surface for long periods of time unless neutralized in some way, such as ionization
Any material that does not conduct electricity Glass and rubber are common insulators These materials are made of atoms which don't allow electrons to move freely, which means there can be no electric current
{i} something which blocks or retards the passage of heat (or electricity, sound, etc.)
Material that is very poor conductor of electricity Mica, glass, porcelain, rubber, paper, plastic, oils and varnishes are considered good insulators
Something that does not allow electricity to flow through it easily Glass and special rubber are good insulators Insulators do not allow electricity to flow through them easily because the electrons in their atoms do not move easily from atom to atom
A material that prevents the passage of heat or electricity or sound into or out of it
A non-conductive structure or device that does not transmit sound, heat, or electricity
Material through which the flow of electrical charge carriers or heat is greatly reduced
An INSULATOR is a material or object through which electricity cannot easily pass Some common insulators are porcelain, glass, rubber and wood
A device, made of non-conducting material, used to give support to electrical conductors and shield them from ground or other conductors An insulator inhibits the flow of current from the conductor to the earth or another conductor
Materials such as plastic, quartz, ceramics, glass and silicon that do not conduct current Charge on an insulator will not distribute itself over the material's entire surface, but will stay fixed at the generating site Back to top
"Jewels of the wire" as they are known by American collectors, are not readily found in South Africa but are extremely collectable overseas There are more than 20 websites dedicated to insulator collecting
