Insulator definition

A material or an object that does not easily allow heat, electricity, light, or sound to pass through it. What does insulated mean? Definition of insulator. An insulating material used in bulk to wrap electrical cables or other equipment is called insulation.

The term insulator is also used more specifically to refer to insulating supports used to attach electric power distribution or transmission lines to utility poles and transmission towers.

They support the weight of the suspended wires without allowing the current to flow through the tower to ground. Any material that keeps energy such as electricity, heat, or cold from easily transferring through is an insulator. Woo plastic, rubber, and glass are good insulators. Insulator, any of various substances that block or retard the flow of electrical or thermal currents.

Insulator may refer to: Insulator (electricity), a substance that resists electricity Insulator (genetics), an element in the genetic code. Thermal insulation, a material used to resist the flow of heat Building insulation, the material used in building construction to prevent heat loss Mott insulator,. The insulator sheets are used on molds and dies between the top clamping plate and the stationary platen and between the bottom of the ejector housing and the movable platen.

The definition of an insulator is something that is used to keep heat or sound containe or something that does not conduct electricity.

Soundproofing material is an example of an insulator. Electricity a material of such low conductivity that the flow of current through it is negligible. Wool is fluffy and airy so it serves as an insulator to prevent the heat of the body from escaping.

Solid ice is a poor insulator , when compared to compressed snow. If hindered from escaping by an insulator , the heat accumulates to a degree that can be exploited for generating electricity. Insulation is the process of keeping heat, soun or electricity from spreading. If you can hear your neighbor snoring at night, you might need better sound insulation. This contrasts with other materials, semiconductors and conductors, which conduct electric current more easily.

Not surprisingly, materials that are good conductors have high conductivity, while materials that are good insulators have low conductivity. The conductivity of a material is dependent on the number of free electrons available, and this varies greatly between the different types of atoms. Oxford Dictionaries as A substance which does not readily allow the passage of heat or sound.

Find out information about insulator. A device having high electrical resistance and used for supporting or separating conductors to prevent undesired flow of current from them to other objects. Under the action of the same or identical electric forces the intensity of this state in various insulators is determined by a quality of them called their dielectric constant, specific inductive capacity or inductivity. Insulators protect conductors and protect people from conductors.

Whether a material is a conductor or an insulator depends on its atoms and on the relationship of each atom to its surrounding atoms.

Conductors carry electric current. In summary, an insulator is any material that prevents the transmission of electricity, heat, or sound. Electrical insulators prevent electrons from moving through a substance. This keeps electricity on the correct and most efficient path in our homes.

Plastic, wood and glass are good electrical insulators. In contrast to conductors, insulators are materials that impede the free flow of electrons from atom to atom and molecule to molecule. Materials that do not conduct heat or electricity are known as insulators.

If charge is transferred to an insulator at a given location, the excess charge will remain at the initial location of charging.
