Circular cable trays in Lebanon can be installed using locally available wiremesh, solid, or perforated trays with flexible support systems, complying with international standards for safety and efficiency.

Types of Cable Trays Available

In Lebanon, suppliers like Legrand and SFSP offer a variety of cable trays suitable for circular or curved installations:

• Wiremesh Cable Trays (Cablofil): Highly flexible, 90% open structure for airflow, easy visual inspection, and minimal dust retention. Quick-fixing systems like Faslock auto allow on-site bends without special tools, ideal for circular routing .
• Solid or Perforated Sheet Metal Trays (P31 range): Available with convex and concave risers, 15°/30°/45°/90° bends, adjustable bends, and T-junctions. These trays provide high mechanical strength and fire resistance (E30/E90 certified) for curved installations .
• Basket Tray Systems: High-strength welded steel wires, continuous airflow, and fast connections with minimal tools, suitable for circular layouts .

Support and Accessories

Proper support is essential for circular cable tray installation:

• Wall brackets, suspension brackets, hangers, Strut rails, trapeze mounting systems, and ceiling brackets are available to maintain stability and alignment .
• Automatic couplers and interlocking systems simplify alignment and junction stability for curved sections .
• Accessories like end pieces, vertical junctions, and T-junctions allow smooth transitions in circular or curved paths.

Installation Guidelines

1. Planning the Route: Determine the circular path and radius, considering cable bend radius and load capacity.
2. Selecting Tray Type: Choose wiremesh for flexibility and ventilation, or solid/perforated trays for heavy-duty or fire-rated applications.
3. Mounting Supports: Install brackets or hangers at recommended intervals (per manufacturer guidelines) to prevent sagging.
4. Bending and Joining: Use pre-fabricated bends or on-site adjustable bends; interlocking systems or Faslock auto can simplify connections.
5. Cable Laying: Lay cables evenly, avoiding sharp bends, and maintain spacing for airflow and heat dissipation.
6. Compliance: Ensure installation meets IEC 61537, NEMA, BS EN standards, and local electrical codes .

Material and Finish Options

• Pre-Galvanized, Hot-Dip Galvanized, Stainless Steel (304L/316L), Aluminium for corrosion resistance and durability .
• Surface treatments and finishes are selected based on indoor, outdoor, or offshore environments.
