HDPE Corrugated Duct 77mm OD, With 3 Sub-ducts
HDPE Corrugated Duct 77mm OD with 3 Sub-Ducts
Premium Multi-Cable Protection for GCC Telecom & Electrical Networks
Key Features
✔ EFFICIENT CABLE ROUTING WITH 3 SUB-DUCT SYSTEM
The three sub-ducts that are uniform allow the installation of multiple cables next to each other without any issue of interference or tangling.
✔ HDPE CONSTRUCTION WITH HIGH DENSITY
HDPE not only gives the strength of being a tough plastic but also the ability to withstand impacts, weather, chemicals, and pressures.
✔ OUTER DESIGN WITH CORRUGATION
It can be re-directed easily, however, its strength is still enough for it the load that comes with being buried underground.
✔ UV AND HEAT RESISTANT
Ideal for outdoor installation during the Gulf's harsh climatic conditions.
✔ INNER SURFACE THAT IS SMOOTH
It lowers the amount of force that has to be applied during the pulling of the cable and makes it possible to pull it over longer distances.
✔ LIGHTWEIGHT AND INSTALLATION IS EASY
The overall cost of transport and labor is reduced significantly due to this factor.
✔ MAINTENANCE-FREE OPERATION
The equipment requires very little maintenance and provides performance of many decades once it’s installed.

How It Is Used (Step-by-Step Process)
1. Trench Preparation
Digging the trench or path has to be done in accordance with the project requirements for depth and dimensions.
2. Duct Placement
Installation of the 77mm HDPE corrugated duct is to be done in the trench or cable way.
3. Jointing & Extension
Piping lengths should be joined with the help of couplers or connectors.
4. Sub-Duct Identification
It should be indicated clearly which sub-duct corresponds to what cable.
5. Cable Pulling
Using pulling ropes or fish tape will ensure a smooth cable insertion.
6. Backfilling
Using fine soil or sand as backfill will not only give support but also protect against sharp stones.
7. Sealing & Testing
The ends of the ducts are to be sealed and a test for blockages or collapse done.

Conclusion
The HDPE-Corrugated Duct 77 mm OD with 3 Sub-Ducts is a pioneer, strong and powerful tool for more than just multi-cable installations in Saudi Arabia but also in the Gulf region. Its ability to withstand extreme conditions is one of the main features of the duct and therefore thermoplastic gives its long life to the whole installation including the telecommunications, fibre-optics, electric, and industrial cables.
The duct's interior design, which is able to house a large number of cables, and at the same time the endurance of HDPE make it fully future-proof choice for contractors, telecom operators, MEP companies, utility providers, and government infrastructure projects. The duct in smart cities, highways, renewable energy projects, or commercial installations not only ensures high performance, low maintenance, but also provides reliable cable management for decades.
