HDPE Corrugated Duct

Introduction – Saudi Electricity PECD 110mm 4 in-built 38/32mm Subduct

The Saudi Electricity PECD 110mm 4 in-built 38/32mm Subduct is a multi-breakout duct system made of HDPE that allows for orderly cable running and underground building projects. The 110mm outside diameter of the duct and the 38/32mm diameter of the subduct create the possibility of establishing internal routes for conducting wires through the ducts, thus enhancing the quality of separation between cables and ensuring order of installation and maintenance of the network in the future.

The presence of the pull ropes ensures a substantial advantage when laying cables owing to the presence of a ready-made pulling way inside the subducts, thus allowing the installation crews to make the pulling process easier and reducing the need for other pulling solutions.

This PECD construction is intended for use in projects connected with the issues of electricity supply, telecommunications, fiber optics, broadband provision, and underground communication network laying.

Product Overview

This particular subduct made by Saudi Electric, called PECD 110mm, is an outer duct that consists of a PECD outer pipe made of 110mm in size that contains 4 in-built pipe passages in 38/32 diameter with pull ropes.
The subduct system allows for the different cable paths to be made inside the large outer pipe. The subduct allows the works to be divided into pieces of work instead of putting one or many cables into one duct.
This arrangement is really helpful in the installation process of wires when the cable routing plays an important role in the installation process and also for future development of the whole project.
As the name shows, we are dealing with a product produced by Saudi Electricity Company, so it is important to know exactly what is the size since mistakes can happen while buying it.

Key Features

1. Outer duct of 110mm PECD

The 110mm PECD outer duct serves as the main protection channel of this system. The outer duct with a larger cross-section accommodates the system of internal subducts and gives the required structure for cable laying underground.

2. Subducts of 38/32mm size

The system has 38/32mm subducts that provide internal paths for installing the cables. The dimensions of the subducts have to be verified according to the approved drawings and the datasheet data before using them.

3. Pull wires are incorporated

The inner ducts are equipped with pull wires for facilitating the process of pulling the cables. The presence of pull wires inside the subducts makes the preparation process of cable laying much easier.

4. Well-structured paths for the cables

Having several independent paths makes it possible to separate cables and have a better management of the underground rendszer.

5. Duct made of HDPE materials

The HDPE ducts are widely used for underground communications because they possess all the properties necessary for such facilities.

6. Suitable for Infrastructure Projects

The configuration can be considered for underground power, telecom, fiber optic, broadband, and other cable infrastructure where dedicated duct pathways are required.

7. Easier Cable Installation Planning

Dedicated subduct pathways allow installation teams to plan cable routes more systematically, particularly on projects involving multiple cable systems.

Technical Specifications

Important: The exact number of internal subducts, wall thickness, rope specification, color configuration, SDR/classification, operating temperature range, and other dimensional details should be confirmed from the manufacturer’s approved datasheet or project specification before procurement.

Understanding the 38/32mm Subduct Configuration

The 38/32mm specification is very significant in terms of product specification.

In duct engineering, this kind of measurement can refer to the nominal exterior and interior sizes of the subduct used, but this meaning should be checked against the technical datasheet of the manufacturer.

Regarding project presentation, it is particularly important to know the confirmed internal diameter since the size of the wire, way of installation of the wire, pulling force, bending radius, and available free space all play a role in the issue of whether a specific wire can be installed correctly.

In this context, engineers need to check the following:

• The external diameter of the subduct
• The internal size of the subduct
• The cable diameter
• The presence of a free internal volume
• The cable pulling conditions
• The minimum bending radius
• The pulling force
• The length of the route
• The number of bends and transitions.

This verification contributes to the assurance of compatibility of the Saudi Electricity PECD 110mm 38/32mm Subduct to the cable system.

Pull Rope for Cable Installation

One of the most useful features of this type of duct is the built-in pull ropes.

When installing underground cables, a pre-prepared pull rope can provide an interface between a cable and the equipment used for pulling it. This allows for a more controlled initial pulling of the cable without needing to set up separate pull arrangements.

Before starting the installation work, the contractors must check the material of the pull rope, its diameter, tensile strength, fixing method, and the procedures for the installation recommended by the manufacturer.

The pulling system has to be used only within the limits established by the manufacturer.

Cable Separation and Route Organization

The subduct system is especially advantageous due to the creation of a dedicated cable route.

When installing cables in an open duct, various cables may share the same space. Using a subduct system separates and organizes cables into their respective paths.

This allows for:

• Improved cable routing
• Easier identification of cable routes
• Simplified maintenance of cable routes
• Well-defined expansion of the cable system
• Reduced confusion about cable routing
• More detailed documentation

It is especially beneficial for big infrastructure projects where the installation of various cabling systems changes over time.
