Installation Guide
- Site Assessment & Trench Design: Determine the location, depth, and straightness of the trench.
- Excavation: Dig out rocks and other materials, and make the trench base even.
- Bedding Preparation: Pour in sand or soft earth to shield the duct.
- Laying Duct Sections: Put the pieces together considering the correct slope and position.
- Jointing: Employ solvent welding or mechanical couplers for durable connections.
- Cable Pulling: Feed the wires using lubricants to lower the friction.
- Backfilling: The ducts are secured and the cables are protected by layered compaction.
- Warning Tape Installation: Install above the ducts for safety during future excavation.
Accessories & Fittings
Solvent Weld & Mechanical Couplers: For strong, leak-proof joints.
Elbows (45° & 90°): Smooth directional changes.
