Which of the following materials is commonly used for conduits?

Rigid PVC is commonly used for conduits due to its advantageous properties that make it suitable for electrical and telecommunications installations. PVC, or polyvinyl chloride, is a durable plastic material that is resistant to corrosion, chemicals, and moisture, which helps protect electrical wiring from damage and prolongs the lifespan of the installation. Additionally, rigid PVC conduits are lightweight, easy to install, and can be molded into various shapes and sizes, making them very versatile for different applications.

The effectiveness of rigid PVC in providing electrical insulation enhances safety in various environments, which is crucial in maintaining the integrity of electrical systems. Its non-conductive nature also makes it an ideal choice for preventing any electrical faults or hazards. Other materials like wood, glass, or rubber do not provide the same level of performance and protection as rigid PVC in the context of conduit use.
