Best Answer

In case of electrical insulator the electrons are tightly bound to the nuclei of the atoms and no free electrons are available. In reality free electrons are the carriers of electrical charges through the conductor. As free electrons are not available then current becomes zero for even little bit high voltages. Glass, mica, rubber are examples.
