Heavy-Duty Direct Burial Electrical Conduit for Power, Telecom & Utility Projects in KSA & Gulf Region
The infrastructural progress in Saudi Arabia as well as the whole Gulf region necessitates the use of underground conduits that are not only strong and high-capacity but also economical. The choice of the conduit for such applications as power distribution, fiber optic networks, municipal utilities, and industrial installations shall determine the degree of safety, the length of service, and the maintenance costs.
The PVC Type DB‑100 Conduit – 75 mm (2½″) | Direct Burial is specifically designed for underground cable installations that involve large-scale and high-capacity types of cables. It offers heavy-duty protection, resistance to corrosion, and is also easy to install. Its 75 mm diameter permits running multiple cables within one conduit, thereby meeting the present project requirements and allowing future expansion.
The PVC Type DB-100 Conduit – 75 mm (2½″) is a heavy-wall rigid PVC conduit which is intended for direct burial applications thus giving maximum protection to the underground electric, telecom, and control cables. The DB-100 classification of this product makes it superior in mechanical strength and therefore it is suitable for each and every type of project across the Gulf region consisting of residential, commercial, municipal, and industrial like Saudi Arabia, UAE, Qatar, Oman, Bahrain, and Kuwait.
This conduit with a 75 mm inner diameter allows for large cable bundles or multiple cable runs and hence is a perfect match for power distribution, fiber optic, and communication networks with a high capacity. The thick wall of the DB-100 type conduit protects the wires from soil pressure, slight impacts, and other environmental stressors while direct burial without concrete encasement minimizes installation costs and thus quickens project timelines.
Using high-quality rigid PVC as a material, it is immune to corrosion, chemically stable, and a non-conductor thus giving safe and reliable performance even in the harsh environment of the Gulf region. With a lifespan of 30–50+ years, the PVC DB-100 75 mm conduit is a reliable, cost-effective, and future-proof solution for all underground cable installations that do not require frequent maintenance.

PVC Type DB-100 Conduit - 75 mm (2½″) is a heavy-wall rigid PVC conduit suitable for underground installations where direct burial is done. The large size of the conduit enables a number of cables with high capacity to be installed simultaneously, such as power feeders, communication, and fiber optic lines. The DB-100 rating guarantees the highest mechanical strength, giving cables the protection against soil pressure, minor impacts, and environmental stress.
DB‑100 conduits are heavy-wall PVC conduits designed for direct burial, providing maximum mechanical and environmental protection for underground cabling.
Key Characteristics:
Heavy-wall for high mechanical protection
Suitable for direct burial without concrete encasement
Resistant to soil pressure, moisture, and minor impact
Ideal for residential, commercial, municipal, and industrial projects
The PVC material is not susceptible to rusting or corroding and it can thus be used in poisonous, alkaline or wet soils.
The material preserves its performance even at very hot temperatures, which are typical of the Gulf countries.
The non-conductive feature of the substance eliminates any possibility of stray currents or earthing problems.
Its lightness makes transportation, handling, and installation easier which in turn cuts down on labor costs and project timelines.
The underground cable protection will be reliable for a period ranging from 30 to 50+ years.
