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

The smart city project alongside the digital infrastructure and advanced connectivity in the Kingdom of Saudi Arabia and the Gulf region has made it a common scenario that high-quality cable protection systems are in more demand than before at the same time. Meanwhile, the conduits required for modern telecom, fibre-optic, power distribution, and industrial facilities must possess durability, multi-cable capacity, flexibility, and long-term reliability.

The 77 mm OD HDPE-Corrugated Duct with 3 Sub-Ducts is one of the products that has a very high demand all over the locations of KSA, UAE, Oman, Qatar, Bahrain, and Kuwait. The duct is a multi-cable installation solution and provides a secure, easy, and efficient way for the telecom, power, fiber, and low-voltage cables and industrial wiring to pass through.

The duct is made of HDPE, which is high-density polyethylene, and has a corrugated outer surface. This has been specially designed and therefore, offers the best combination of strength, impact-resistance, temperature-stability, and flexibility making it the perfect choice for both underground and surface installations. Moreover, the three sub-ducts inside the main duct provide individual channels, thereby reducing cable interference and making future upgrades more accessible.

The HDPE-Corrugated Duct 77 mm OD with 3 Sub-Ducts is a versatile and high-strength conduit designed for projects requiring multiple cables in a single ducting system. Its three sub-ducts make it ideal for installations where cables must remain separate, organized, and easily accessible for maintenance.

The duct is engineered to withstand harsh Gulf environmental conditions, including:

Intense UV radiation
Sandstorms and abrasive soil
Extreme heat (often crossing 50°C)
Saline coastal environments
Heavy underground pressure

Constructed from premium HDPE, the duct offers a smooth inner surface that ensures low friction during cable pulling, along with a corrugated outer profile for excellent flexibility and structural strength.

It is widely used in:

Telecom networks
Fibre-optic FTTH/FTTB projects
LV & MV electrical routing
Traffic management systems
Smart city cable infrastructure
Industrial automation
Solar and renewable energy cable pathways

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.

HDPE Corrugated Duct Technical Guide & Industry Best Practices

HDPE Corrugated Duct with Subducts vs Without Subducts

Feature	Corrugated Duct with Subducts	Corrugated Duct Without Subducts
Cable Organization	Excellent – separate fiber paths	Single cable path
Network Expansion	Easier future expansion	Limited expansion capability
Cable Protection	High	High
Installation Efficiency	Faster cable management	Requires additional subduct installation
Typical Use	FTTx networks and telecom backbones	Standard underground cable protection

Best Industry Practices for Installing HDPE Corrugated Telecom Ducts

- Maintain trench depth of 700 to 1200 millimeters, based on the infrastructure load.
- Use a sand bed or protective backfill to protect the duct from damage.
- Install detectable warning tape above duct routes.
- Maintain spacing between ducts for ease of maintenance access.
- Seal duct openings to prevent water and debris from entering the duct.
- Follow telecom infrastructure standards for the installation of fibre cables.

The above practices will support long-term reliability of fibre networks and the safety of infra structure.
