PVC Type EB-35 Conduit – 225 mm (9″)

Heavy Concrete Encasement Duct for KSA & Gulf Infrastructure

The PVC Type EB-35 Conduit – 225 mm (9″) | Heavy Concrete Encasement is the full construction of the maximum heavy concrete protection, the most durable underground electrical and utility infrastructure with the longest life expectancy of anywhere. When talking about heavy concrete encasement, this conduit holds its own ground by granting power and communication cables a superior guarantee against very high weights, soil pressure and any kind of environmental stress.

Having the very wide 225 mm internal diameter, this EB-35 conduit is the perfect match for high-capacity power feeders, utility corridors, duct banks, substations and industrial facilities all over Saudi Arabia and the GCC. Its classification as heavy-duty implies a lot of heavy-duty applications in different areas of concern like airports, metros, oil & gas facilities, data centers and smart cities.

The conduit is made of high-quality rigid PVC which will not corrode, moisture, chemicals, and high temperatures, offering guarantee of reliable performance in extreme climate of the Gulf. It is a future-ready solution for those projects that are put in mind safety, scalability, and extended service life.

The PVC Type EB-35 225 mm conduit is a heavy-duty rigid PVC duct designed exclusively for concrete-encased underground installations. The EB-35 rating indicates enhanced wall thickness and compressive strength, making it suitable for environments exposed to heavy vehicular loads, deep burial, and structural stress.

Key Product Highlights

  • Heavy-duty EB-35 classification

  • 225 mm (9″) large diameter for multi-cable systems

  • Rigid PVC construction for strength and longevity

  • Smooth internal bore for easy cable pulling

  • Non-conductive and corrosion-proof

  • Fully compatible with PVC couplers, bends, spacers, and inspection chambers

This conduit is widely used where future cable expansion, operational reliability, and minimal maintenance are required.

Key Features and Benefits

1. Heavy Mechanical Protection

The outlook of the product is its capacity to bear combo of high soil load, traffic load, and structural stress plus tons of weight when buried in concrete.

2. Large Cable Capacity

The size of 225 mm diameter is a good option for large power cables, fiber optics, and a control system installed in one duct.

3. Electrical Safety

Grounding risks and electrical hazards are eliminated by the use of non-conductive PVC.

4. Corrosion & Moisture Resistance

A perfect selection for saline soils, coastal areas, and chemically aggressive environments, such as those found in the Gulf.

5. Smooth Internal Bore

The smooth internal bore diminishes friction, thus causing less cable damage and faster installation.

6. Extreme Climate Performance

Keeps the structure sound when subjected to very high temperatures and desert-like conditions.

Applications

  • Utility duct banks

  • High-voltage and low-voltage power distribution

  • Substations and transformer yards

  • Airports, metros, and rail projects

  • Oil & gas and petrochemical facilities

  • Data centers and industrial zones

  • Municipal and smart city infrastructure

  • Commercial and industrial foundations

Installation Method (Concrete Encasement)

  1. Route Planning & Marking – Adhere to sanctioned drawings and calculations of load
  2. Excavation & Bedding – Dig trench with correct positioning
  3. Conduit Laying – Place EB-35 conduits with the help of spacers
  4. Jointing – Apply solvent weld or mechanical coupling
  5. Concrete Pouring – Protect cable structurally by burying it completely in the concrete
  6. Curing & Cable Pulling – Once the curing is done, pull cables in a gentle manner.

Compatible Fittings & Accessories

  • Heavy-duty PVC couplers

  • Long-radius bends (45° / 90°)
