The PVC 7-Hole Plum Tube is an innovative multi-channel conduit designed for organizing and protecting fiber optic, telecom, and power cables. Its unique 7-core honeycomb structure maximizes space efficiency while ensuring robust cable management. Manufactured from high-grade rigid PVC, this conduit offers exceptional impact resistance, corrosion resistance, and a service life exceeding 50 years. Ideal for underground utility projects, it simplifies installation and reduces long-term maintenance costs
.
Key Features & Advantages
Optimized Multi-Core Design
The honeycomb configuration provides separate channels for different cable types, preventing tangling and interference. Each tube’s smooth interior allows easy cable pulling, reducing friction by up to 40% compared to traditional pipes
.
Lightweight & Durable
Weighing 1/8 of conventional concrete or metal conduits, the plum tube simplifies transport and handling. Its PVC material resists chemicals, moisture, and UV radiation, maintaining structural integrity in temperatures from -40°C to 80°C
.
Easy Installation & Cost Efficiency
The integrated sleeve-and-sub-pipe design eliminates the need for secondary installation. Coupled with push-fit connections, it reduces labor time by 50% and project costs by 20–30% compared to PE/MPP alternatives
.
High Flexibility & Space-Saving
With a bending radius of up to 4 meters per 6-meter tube, it adapts to terrain obstacles without additional fittings. Its compact design reduces trench excavation width by 90% versus, minimizing urban disruption
