It is usually a material that has no free electrons in its out valance rings. This condition makes it hard for free electrons to move from one atom to another atom easily. Without this movement of electrons the material is classed as an insulator. Easy movement of electrons from one atom to another is classed as a conductor the very opposite of an insulator.
In the electrical field, the purpose of any insulating material is to separate electrical conductors without passing current through it. Material like PVC, glass, asbestos, rigid laminate, varnish, resin, paper, Teflon, and rubber are very good electrical insulators. Insulating material is used as a protective coating on electrical wire and cables.

What does Good electrical insulator mean?
An insulator is a material that does not conduct well, so an electrical insulator is a material that does not conduct electricity well. A metal is a bad electrical insulator as it has delocalised electrons, therefore conducts electricity, but most plastics and materials like rubber do not conduct electricity, so they are good electrical insulators. Hope that makes sense and helps? :3AnswerAn insulator is a material with insufficient free charge carriers to support conduction.
Is leather is a conductor of electicity?
Leather is not a good conductor of electricity. It is an insulator, meaning it does not allow electricity to flow through it easily.
