[0002] CPVC power conduit is commonly used as cable protection conduit. This product features high strength, good flexibility, high temperature resistance, corrosion resistance, flame retardancy, excellent insulation properties, no pollution, resistance to aging, light weight, and easy installation. However, cable protection conduits require a cap. For example, a Chinese patent (publication number: CN107947066A) discloses a cap for the opening of a cable protection conduit. Traditionally, the port is sealed with cement to prevent the entry of rainwater, mud, and debris, protecting the cable for normal and safe use. This type of cap cannot be opened and is prone to corrosion over time. Caps require specific models and require threads at the opening of the conduit, making them less adaptable.
