Technical Field

[0001] The utility model relates to the technical field of power cable protection pipes, in particular to an antioxidant multi-layer PVC power cable pipe. Background Technique

[0002] With the rapid development of the power industry, as the main carrier of power transmission, the safety and reliability of power cables have received increasing attention. In order to protect power cables, corresponding power cable pipes are required.

[0003] A PVC power cable protection pipe with the reference publication number of CN205565655U includes a CPVC plastic pipe body. A first heat insulation layer is arranged on the outer side of the CPVC plastic pipe body, and the first heat insulation layer is composed of ceramic microbubble heat insulation and heat preservation coating. A flame retardant layer is arranged on the first heat insulation layer, and the flame retardant layer is composed of magnesium hydroxide flame retardant material. A second heat insulation layer is arranged on the inner wall of the CPVC plastic pipe body, and the second heat insulation layer is uniformly coated with polytetrafluoroethylene material. Among them, the connecting sleeve and the CPVC plastic pipe body are fixedly connected to each other by hot melting and heat connection. Such a connection method can melt the connecting sleeve and the CPVC plastic pipe body into one body, ensuring the connection and installation stability of the PVC power cable protection pipe after laying. According to the above, although this power cable pipe can be well applied, it is usually not convenient to shield and protect both ends of the cable pipe in the unused state, resulting in the phenomenon that external dust easily flows into the cable pipe and erodes its interior, which often troubles users.

[0013] (1) Through the settings of the first magnetic suction ring and the second magnetic suction ring, the first circular metal baffle and the second circular metal baffle are respectively adsorbed and installed at one end of the first annular connection seat and the second annular connection seat. Thus, the two circular metal baffles can shield and protect both ends of the cable pipe in the unused state, thereby reducing the phenomenon of dust flowing into the cable pipe interior and causing erosion;
