What is the primary purpose of using Schedule 80 PVC in electrical installations?

The primary purpose of using Schedule 80 PVC in electrical installations is its strength and durability. Schedule 80 PVC is thicker than Schedule 40 PVC, providing a greater resistance to impact, higher pressure ratings, and improved structural integrity. This more robust construction makes it suitable for environments where there may be physical stress, potential impacts, or exposure to harsher conditions, such as underground or exposed installations.

Additionally, its durability helps protect electrical conductors and components from damage due to environmental factors, which is crucial for maintaining the integrity and safety of electrical systems. While factors like cost, weight, and insulation properties might be considerations in various contexts, the standout feature of Schedule 80 PVC is its ability to withstand rigorous conditions, making it the preferred choice for ensuring long-lasting installations.
