Why PVC DB‑120 is Ideal for Gulf Region

  1. High Heat Resistance: Does not lose its strength even when exposed to very high temperatures in the desert.
  2. Saline and Alkaline Soil Resistance: Prevents wear and tear caused by soils of coastal areas.
  3. High Mechanical Strength: Acts as a shielding material to withstand both static soil and dynamic surface loads.
  4. Lightweight Construction: Makes the process of managing and installing easier.
  5. Long-Term Durability: Guarantees a service life of 30–50+ years, which significantly reduces maintenance costs.

Installation Guide

  1. Site Assessment & Trench Design: Determine the location, depth, and straightness of the trench.
  2. Excavation: Dig out rocks and other materials, and make the trench base even.
  3. Bedding Preparation: Pour in sand or soft earth to shield the duct.
  4. Laying Duct Sections: Put the pieces together considering the correct slope and position.
  5. Jointing: Employ solvent welding or mechanical couplers for durable connections.
  6. Cable Pulling: Feed the wires using lubricants to lower the friction.
  7. Backfilling: The ducts are secured and the cables are protected by layered compaction.
  8. Warning Tape Installation: Install above the ducts for safety during future excavation.
