More information

Insulators are commonly used as a flexible coating on electric wire and cable. Since air is an insulator, no other substance is needed to keep power where it should be. High-voltage power lines commonly use just air, since a solid (e.g., plastic) coating would be impractical. However, wires which touch each other will produce cross connections, short circuits, and fire hazards.
