This utility model relates to the field of power facility technology, and in particular to a PE and PVC blended structural wall
pipe. The technical solution includes: a
pipe body and an overhead ring. The
pipe body is composed of a non-toxic bitter layer, a hardened layer, a composite layer, a core, and an antistatic
coating. The non-toxic bitter layer, hardened layer, composite layer, core, and antistatic
coating are arranged sequentially from the outside to the inside. The outer ring surface of the overhead ring is equidistantly fixed with ball seats, and rolling balls are rotatably mounted on the ball seats, rolling in contact with the inner wall of the pipe body. This utility model, through the synergistic design of a multi-layered composite protective pipe body and a ball-supported overhead ring, achieves an integrated cable protection structure that is
rodent-proof, abrasion-proof, antistatic, and has high-strength
compressive strength, significantly improving the safety and durability of cable laying.
