Description

Technical Field

[0001] This utility model belongs to the field of cable conduit technology, specifically relating to an anti-tangle high-strength CPVC power cable conduit. Background Technology

[0002] Power cable conduits, also known as power cable protection pipes, are primarily installed at intersections where communication cables and power lines cross. They prevent short circuits caused by power line breaks, which could energize communication cables and steel ropes, protecting cables, switches, circuit boards, and even the entire device from burnout. They also provide some isolation against magnetic field interference from power lines. Power cable conduits are made from various materials; CPVC power cable conduits use heat-resistant and highly insulating CPVC resin as the main material, and are rigid, solid-walled pipes. Currently, CPVC power cable conduits are generally single-hole pipe structures. When multiple power cables pass through the conduit, they are prone to tangling, which can damage the cables and hinder maintenance. Furthermore, when there are many power cables in the conduit, their weight is significant, putting considerable pressure on the conduit when it is suspended. The conduit also sometimes has to withstand significant external pressure. Therefore, the existing design of CPVC power cable conduits needs further improvement. Utility Model Content

A flame-retardant layer and a wear-resistant layer are sequentially provided on the outside of the middle rubber layer. Two corresponding connectors, a first connector and a second connector, are fixed at both ends of the pipe body. The first connector includes an annular plate, with a connecting cylinder on the inner side of the annular plate. Multiple through holes are evenly distributed on the annular plate. First, a positioning head is provided on the outer side of the annular plate 1; the second connector includes an annular plate 2, and a connecting cylinder 2 is provided on the inner side of the annular plate 2. Multiple through holes 2 are evenly distributed on the annular plate 2, and positioning holes adapted to the positioning head are provided on the outer side of the annular plate 2; the first connecting cylinder and the second connecting cylinder are both fixed to the pipe body by an adhesive layer; the inside of the pipe body is provided with a pipe rack with a quincunx cross-section, and the pipe rack is provided with multiple through holes for cables to pass through; the inner diameter of the pipe body is equal to the inner diameter of the annular plate 1 and the annular plate 2.
