A prefabricated power duct

This utility model discloses a prefabricated power duct, including a duct body with multiple reinforcing bars cast inside. The duct body has an inner cavity with a pipe hole. Multiple lifting rings are fixedly connected to the upper surface of the duct body. A limiting component is fixedly installed inside the pipe hole to clamp cables of different diameters, ensuring cable operation safety. A protective component for wrapping the cable is slidably installed inside the pipe hole to prevent damage to the cable insulation layer and ensure cable lifespan. The limiting component and the protective component work together to clamp and fix the cable, ensuring that the cable does not shift or loosen during long-term operation. It also accurately corrects the direction during the initial cable insertion, reducing the risk of scratches caused by angular deviations. This comprehensively protects the cable insulation layer, preventing faults caused by friction, displacement, or entanglement, ensuring long-term stable cable operation, and reducing maintenance risks and costs.
