HDPE cable conduit is manufactured from PE100 or PE80 high-density polyethylene, engineered specifically for buried power and communication cable protection. It provides outstanding electrical insulation, compressive strength and corrosion resistance.

High ring stiffness allows the pipe to withstand vehicular loads and deep soil pressure without cracking or deformation. It is resistant to acids, alkalis, salts and extreme temperatures, performing reliably in deserts, swamps, mountainous areas and coastal regions. The smooth inner wall reduces pulling friction for easy cable installation, while good flexibility permits bending around underground obstacles.

Joints are made via butt fusion or electrofusion, ensuring watertight sealing. The conduit is widely used in urban grid renovation, municipal power networks, residential underground cabling, industrial park power distribution, road and bridge construction and rail transit cable protection.

Notes on pipelines：

1. The pipeline shall be laid with a certain drainage slope to prevent accumulated water from corroding the cable; joint sealing must be tight to avoid water and moisture intrusion.

2. When pulling cables, control the traction force evenly, use special traction tools, and prohibit forced dragging to prevent scratching the cable insulation layer and pipe inner wall.

3. The minimum bending radius shall not be less than 12 times the pipe outer diameter, avoid sharp bending, folding and distortion, so as not to affect cable threading and pipeline mechanical strength.

4. In road sections, parking lots and other areas with heavy vehicle loads, increase the buried depth or add concrete protection layer to prevent pipeline crushing and deformation.

5. Hot-melt connection shall be operated by professional workers, ensure the joint is fully fused, no virtual welding or leakage; do not use unqualified fittings.

6. Avoid contact with sharp metal objects during trench backfill, prevent pipe wall puncture; do not stack heavy objects on the pipeline surface for a long time.
