PVC-U multi-hole conduit is an integrally extruded multi-duct bundle available in 1, 2, 4, 5 and 7-hole configurations, maximizing space utilization and enabling simultaneous installation of multiple cables with independent routing.

High structural rigidity, deformation resistance, chemical resistance and waterproofing provide reliable cable protection. The conduit can be directly buried with minimal joints, ensuring neat cabling and convenient future expansion, maintenance and cable replacement.

It is widely used in telecom central office cabling, urban utility tunnels, intelligent community low-voltage systems, CATV networks, municipal communication trunks and security monitoring line infrastructure.

Notes on pipelines：

1. Protect each hole of the pipeline during construction, prevent sand, mud and debris from entering, block the hole mouth in time to avoid blockage.

2. Lay the pipeline smoothly, avoid twisting, distortion and sharp bending, ensure the internal holes are not deformed and damaged.

3. The joint connection shall be aligned and sealed, prevent water intrusion and cross-hole interference, facilitate classified threading of different cables.

4. Suitable for communication, intelligent community and comprehensive pipeline network, realize multi-cable simultaneous laying, improve space utilization.

5. Avoid heavy pressure and impact during backfill, protect the integrated multi-hole structure from damage; handle gently to prevent pipe fracture.

6. Regularly check the hole blockage and pipeline deformation, facilitate later cable expansion, maintenance and replacement.
