Advantages Over Metal Conduits
| Feature | uPVC Class 4 | Metal Conduit |
|---|---|---|
| Corrosion Resistance | Excellent | Poor in humid/saline conditions |
| Electrical Insulation | Non-conductive | Conductive, requires earthing |
| Weight | Lightweight | Heavy, difficult to handle |
| Installation | Quick & easy | Requires threading/welding |
| Maintenance | Minimal | Moderate to high |
| Flame Resistance | Yes, self-extinguishing | Depends on coating |
Suitability for Gulf Climate
The severe Gulf weather conditions characterized by extreme temperatures, dust storms, high humidity, and saline atmosphere are really a test for metal conduits. To combat these harsh environments, uPVC Class 4 conduits are created to last with no deterioration, hence the quality and safety of installation is guaranteed.
Safety and Compliance
This conduit meets KSA & GCC building and electrical codes, reducing risks such as:
Cable damage
