Double insolated cases
An electrical appliance which is double insulated does not have an earth wire fitted. The appliance is designed in such a way that the electrical parts can never come into contact with the outer casing of the device. Common double insulated appliances are hair dryers, radios and cassette players. A wet double insulated appliance is exceptionally dangerous - water is a good conductor of electricity and will easily reach the live electrical components within the case. Any human user touching the casing will then receive an electric shock. It is important to note that the human conductivity is increased when hands are wet, allowing a greater current to flow through the casualty. For this reason, do not operate a mains radio, hairdryer or double insulated appliance in any wet area - especially a bathroom Do not touch any person who has been electrocuted until you are sure that the electricity supply has been shut off.

what may happen if wires are not insulated
Drill cases are made of plastic to keep the operator from being electrocuted. This is called "double insulation" - the wiring inside the drill is insulated, and the case of the drill is a second insulator. Some of the gears in a drill are made of nylon because nylon is strong enough for the application and it's less expensive to form into a gear shape.
Hairdryers often have a double-insulated design, which means they have an extra layer of insulation to protect against electric shocks. This eliminates the need for an earth wire in the cable because the double insulation provides adequate protection against electric leakage.
Mugs made of materials such as ceramic, stainless steel, or double-walled insulated tumblers tend to keep water warmer for longer periods of time compared to mugs made of glass or thin plastic. These materials provide better insulation and help retain heat better. Double-walled insulated tumblers, in particular, are designed to keep drinks hot or cold for an extended period due to the air barrier between the walls.

Air insulated substation means air acts as the dielectric medium but in case of gas insulated substation SF6 is the dielectric medium. Gas insulated substations are having more advantages than air insulated substations.
