Abstract
The utility model discloses a buried type middle voltage electric power cable protecting sleeve pipe comprising a protecting sleeve pipe and a screw thread pipe that are interconnected in an integrated manner, the protecting sleeve pipe and the screw thread pipe are made of hard polyvinyl chloride materials, the surface of the protecting sleeve pipe is provided with a strengthening layer, and the two faces of the strengthening layer are respectively connected with a flame retardation layer and a wearing layer. Through the above mode, after being subjected to high temperature extruding and molding operation through a plastic extruding machine, the buried type middle voltage electric power cable protecting sleeve pipe of the utility model is characterized by corrosion resistance, high strength, high temperature resistance, and long service life; voltage of 2000 V and less can be withstood, and critical defects of a cement asbestos pipe are overcome. The buried type high voltage electric power cable protecting sleeve pipe is mainly applied to laying pipelines for electric power cables of 26/35 kV and less.
Description
Technical field
The utility model relates to field of cables, particularly relates to a kind of buried medium-pressure power cable protecting pipe.
