Plastic materials, such as PVC (polyvinyl chloride) and PE (polyethylene), are the most commonly used insulating materials for conductors in electrical wiring and cables. They have good insulation properties, are easy to manufacture and work with, and are relatively inexpensive. Copper and aluminum are conductive materials and not suitable for insulation, while silk is not commonly used due to its high cost and limited availability.
