In insulators the bond energy between atoms in the material they form is very high. We need to give large energy to overcome that bond energy and set free the electrons.
As electrons are not freely available It doesnt conduct well.
There's a kind of circularity in the question. Anything that doesn't conduct electricity for any reason is called an insulator. So any substance where the electrons are too tightly bound to atoms and cannot migrate is called an insulator. Anything that manages to let electrons migrate wouldn't be called an insulator.
Insulators
Conductors conduct heat and electricity well because they have delocalised electrons in their structure. Insulators, on the other hand, do not have delocalised electrons and therefore do not conduct heat and electricity as a conductor, although they do conduct to some extent.
Insulators are materials that don't conduct heat well, or (for electricity), materials that don't let electricity pass through them. In general they are non-metallic materials.
Most metals are well known to be good conductors of heat. Examples of such metals are aluminum and copper. Objects that do not conduct electricity are known as insulators.
In electricity, Insulators help insulate electric charges. Conductors conduct the electric charges and make them into electricity.
because insulators don't conduct any electricity but conductors do conduct electricity
Insulators
No. Insulators by definition don't conduct electricity.

Insulators are materials that don't conduct heat well, or (for electricity), materials that don't let electricity pass through them. In general they are non-metallic materials.
Materials that do not conduct electricity well are Insulating materials, or insulators. Examples include glass, rubber, plastic, air, ceramic, porcelain, dry paper and dry wood. Pure water will not conduct electricity at all.

In electricity, Insulators help insulate electric charges. Conductors conduct the electric charges and make them into electricity.
Pure water does not conduct electricity (insulator) whereas water with dissolved impurities can conduct electricity fairly well (conductor). Water is considered as a universal solvents. Water is absolutely essential for all the chemical reactions in our body.
Conductors conduct electricity because most of them are made of metals and metals are good conductors of electricity while insulators are made of rubber and rubber does not conduct electricity. To conduct electricity, the atoms that make up the material, have to have free electrons that can pass a charge on. Metals have these free electrons, whereas insulators do not.
