uPVC Electrical Conduit – 20 mm (½″) – Class 3 | Medium Duty
uPVC Electrical Conduit 20mm (½″) Class 3 Medium Duty
GCC & Saudi Approved
Understanding 20 mm (½″) Class 3 Medium Duty Conduit
What Does 20 mm (½″) Indicate?
The 20 mm measure is the standard size of the conduit and it is thus applicable for:
- Light circuits
- Wiring for sockets
- Control and signal lines
- Low to medium voltage cabling
This diameter is one of the most often used conduits in wiring plans for both houses and offices.
What Is Class 3 – Medium Duty?
The characteristics of Class 3 conduits are:
- Ability to bear medium mechanical impacts
- The places where the conduits might be prone to being either exposed or buried in concrete
- Greater longevity over Class 2 (Light Duty)
- They are fit for wiring on the surface, installation in slabs, and even in commercial areas where more strength is demanded.

Key Features of uPVC Electrical Conduit 20 mm Class 3
1. Enhanced Mechanical Strength
Class 3 medium-duty conduits are stronger than light-duty conduits, making them suitable for commercial and semi-industrial applications.
2. Excellent Electrical Insulation
Being non-conductive, uPVC eliminates the risk of electric shock and current leakage, ensuring maximum safety.
3. Fire-Retardant & Self-Extinguishing
In the event of fire, the conduit does not propagate flames, helping prevent the spread of electrical fires.
4. Resistance to Heat & Harsh Climate
Engineered for high ambient temperatures commonly experienced in KSA and Gulf countries.
5. Corrosion & Moisture Resistance
Unlike metal conduits, uPVC does not rust, making it ideal for:
Coastal regions
High-humidity zones
Concrete-embedded installations
6. Smooth Internal Bore
The smooth inner surface ensures:
Easy cable pulling
Reduced installation time
Protection of cable insulation

How uPVC Electrical Conduit Is Used (Installation Process)
Step 1: Electrical Planning
All the electrical planning is done on the basis of the already approved drawings and electric installations of the area.
Step 2: Measuring & Cutting
The company employs standard cutting tools for splitting the tubing to the necessary size.
Step 3: Bending the Conduit
Heat is applied in just the right amount to make a bending of the conduit that will not break and will not decrease the strength of the material as well.
Step 4: Fixing the Conduit
The conduit is mounted on the surface using saddles or clamps. In addition, it is also installed concealed inside the walls, slabs, or ceilings.
Step 5: Jointing
Couplers, bends, junction boxes, and inspection boxes create a continuous conduit system.
Step 6: Cable Pulling
With the aid of draw wires or fish tape, the electrical cables are drawn out freely without any blockage.
