The proportion of cables in power lines is gradually increasing.

[0003] Power cable protection pipes are tubular structures that protect power cables. They are mostly made of high-strength materials and are laid underground, in walls, and other environments. They can isolate external factors such as soil corrosion, mechanical impact, and moisture, prevent damage to the cable insulation layer, ensure stable power transmission, and facilitate later cable maintenance and replacement. Each cable protection pipe is connected to the other through a connecting structure.
