High-performance anti-twist MPP power cable protection pipe structure

Abstract

This utility model discloses a high-performance anti-torsion MPP power cable protection pipe structure, belonging to the technical field of cable protection pipes. Its key technical features include a cable protection pipe body, an anti-torsion structure fixedly connected to the inner side of the cable protection pipe body, and buffer mechanisms fixedly connected to both sides of the anti-torsion structure. The double-layer flexible design of the flexible inner sleeve and flexible outer sleeve in the anti-torsion structure can absorb external torsional forces to a certain extent, preventing direct transmission to the cable. A stable frame constructed by connecting plates, connecting rods, and reinforcing ribs tightly connects the flexible inner sleeve, the cable protection pipe body, and the flexible outer sleeve, effectively dispersing stress and improving overall torsional strength. The reinforcing ribs, located on the inner wall of the flexible outer sleeve, enhance the rigidity of the protection pipe, resist torsional deformation, and further ensure cable safety. The buffer mechanism allows the flexible inner sleeve to slide relative to the cable protection pipe body under the restriction of a limiting rod when the protection pipe is subjected to torsional forces.
