The difference between dielectric and insulator lies in its field of application.
Dielectrics are used to store the electric charges, while insulators are used to block the flow of electric charges ( they more or less act like a wall).
While all dielectrics are insulators (they don't allow the flow of electric charges through them) all insulators aren't dielectric because they can't store charges unlike dielectrics.

What is difference between breakdown voltage and dielectric strength of transformer?
The dielectric strenght of a transformer represents the maximum voltage permissible to apply across the transformer insulation i.e. between the transformer winding to another part of the transformer, normally the chassis or another winding and without break-down of the insulation ocurring (e.g. arcing). The breakdown voltage of a transformer represents a voltage that exceeds its dielectric strenght and that causes breakdown e.g. arcing across the insulation.
What is dielectric test in transformer?
why need dielectric test for transformer
What is the sodium hypochlorite dielectric constant?
dielectric constant for sodium Hypochlorite
What is the difference between complex permittivity and static dielectric conatant?
What is the difference between complex permittivity and static dielectric conatant?
What is the definition of a Teflon capacitor?
A teflon capacitor uses teflon as the dielectric, or insulator, between plates.
What is the use of dielectric between capacitors?
A dielectric is an insulator between the plates of a capacitor. They allow us to build the plates closer together, without allowing them to short together, thereby increasing capacitance.
If you take out the battery in a capacitor before inserting a dielectric will there still be charge on the dielectric?
The charge in a capacitor is between the plates. The dielectric is only an insulator that allows the plates to be very close without touching and discharging the charge. There is no battery in a capacitor.
What is the insulator in a coaxial cable called?
It's called the Dielectric
What is dielectric matter?
An electrical insulator that can be polarized by an external electric field.
Why such materials are good insulators?
Dielectric meterials are good insulator materials
Where is the knowledge of dielectric strength helpful?
One field in which this is helpful is in the manufacture of insulating materials. Dielectric strength determines the strongest electric field an insulator can withstand before it fails. For example, if the insulation around a wire melts or breaks, the insulator's dielectric strength is compromised.
Dielectric constant of insulator depends on?
Frequency of alternating field applied & temperature
What is the difference between copper and polystyrene as an insulator?
The mobility of the electrons.
What is the major difference between conductor and dielectric?
A conductor is a material which allows elctronic flow through it with some finite (though usually very small) resistance as opposed to a dielectric, the other name for an insulator, that provides ideally infinite resistance to current flow at all temperatures.
What happens when dielectric breakdown occurs?
The dielectric,usually the insulator between the plates of a capacitor, can be overstressed by the application of too high voltages applied to the capacitor plates. The dielectric breaks down and a current flows between the plates until,either they are discharged, or an equilibrium is reached,below the working voltage of the capacitor. If the dielectric is damaged in this process he capacitor must be replaced. Some dielectric material self heal and can recover from an over voltage.
