PVC Type EB-20 Conduit – 40 mm (1¼″)

Concrete Encased Electrical Conduit for Underground Installations in KSA & Gulf Region

As a part of the Gulf region, Saudi Arabia included, electrical infrastructure projects require the best quality, the longest lasting, and the most regulatory-compliant solutions. The PVC Type EB-20 Conduit 40 mm (1¼″) is made specifically for underground installations in concrete and provides mechanical protection, resistance to any corrosion, and the safety of electrical operations for both low and medium voltage cables.

The 40 mm diameter of the conduit permits larger cable capacity thus it can be used in branch circuits, lighting systems, control wiring, and in low-voltage installations. The EB-20 conduits, when embedded in concrete, offer protection against external pressure, heavy construction loads, and environmental factors which might lead to deterioration of the product thus ensuring long-term reliability in the case of residential, commercial, industrial, and municipal projects.

The PVC Type EB-20 Conduit – 40 mm (1¼″) is a rigid PVC electrical conduit engineered for concrete encasement. EB-20 classification provides medium-duty mechanical protection, safeguarding electrical cables from external forces, soil pressure, and construction activities.

Manufactured from high-grade PVC, the conduit is non-conductive, corrosion-resistant, and highly durable, making it ideal for long-term underground electrical installations. Its smooth internal bore allows easy cable pulling, reducing labor and minimizing cable damage.

This conduit is widely used in building foundations, slabs, duct banks, basements, and underground utility corridors, making it an essential component for Gulf-region infrastructure projects.

Key Features and Benefits

Concrete-Encased Mechanical Protection

Impact, pressure, and heavy construction loads resistance is guaranteed when the material is encased in concrete.

Electrical Safety

PVC is a non-conductive material that completely removes the possibility of electric shocks and grounding problems.

Corrosion & Moisture Resistance

EB-20 PVC is not affected by rust, corrosion, or chemical attack, even in alkaline concrete environments which are very hostile for metals.

Smooth Internal Bore

It makes the cable installation easy and damage-free so as to reduce labor time and effort.

Heat & UV Resistance

It is reliable to operate even in the extreme conditions of Saudi Arabia and the Gulf region.

Lightweight & Installer-Friendly

It is very convenient in terms of handling, transportation, and installation.

Long Operational Life

It is a product with a long life expectancy of being maintenance-free for decades, thus resulting in a cost-effective infrastructure.

Installation Method (How It Is Used)

Step 1: Site Evaluation and Design

Mark the routing of the conduits according to the approved electrical drawings.

Step 2: Trench Preparation or Steel Rebars

Prepare the reinforcing base for trenches or slabs.

Step 3: Conduit Placement

Secure the EB-20 40 mm conduits, ensuring that they are properly aligned.

Step 4: Joining

Generally speaking, PVC couplers are used to join conduits; the joints shall be firmly sealed with appropriate connections and PVC solvent cement.

Step 5: Casting Concrete

Pour concrete around the conduits in a manner that will fasten them.

Step 6: Wire Pulling

After the concrete has hardened, pull the cables with ease through the conduit.

Accessories & Fittings
