Polymer cable trays in Sri Lanka provide a safe, corrosion-resistant, and flexible solution for organized cable management in industrial and commercial installations.

Types of Polymer Cable Trays

Polymer cable trays, also known as FRP (Fiber Reinforced Plastic) or PVC trays, are widely used in Sri Lanka for environments where corrosion resistance, lightweight handling, and electrical insulation are critical. These trays are available in various forms:

• Ladder-type trays: Ideal for heavy-duty cables and long spans.
• Perforated trays: Allow ventilation and heat dissipation for sensitive cables.
• Solid-bottom trays: Provide full protection for cables in dusty or wet environments. Suppliers like PRISMA and Eastlink offer polymer trays with a range of accessories, including bends, couplers, and supports, designed for easy installation and compliance with international standards .

Installation Guidelines

1. Planning and Layout: Determine the cable routes, load requirements, and support spacing. Polymer trays are lighter than metal trays, allowing longer spans between supports, but always follow manufacturer specifications.
2. Support and Fixing: Use brackets, hangers, or wall-mounted supports to secure trays. Ensure proper alignment and leveling to prevent sagging.
3. Joining Sections: Connect tray sections using couplers or splice plates. For polymer trays, avoid over-tightening fasteners to prevent cracking.
4. Cable Laying: Lay cables neatly within the tray, maintaining separation for power, data, and control cables if required. Use cable ties or clamps compatible with polymer materials.
5. Grounding and Bonding: While polymer trays are non-conductive, ensure proper grounding of metallic accessories or hybrid systems if used.
6. Inspection and Maintenance: Periodically check for mechanical damage, UV degradation, or excessive load. Polymer trays require minimal maintenance compared to metal trays .

Advantages of Polymer Cable Trays

• Corrosion Resistance: Ideal for coastal or chemical-prone environments in Sri Lanka.
• Lightweight: Easier handling and installation, reducing labor costs.
• Electrical Insulation: Reduces risk of short circuits and enhances safety.
• Durability: Resistant to moisture, chemicals, and UV exposure.
• Flexibility: Can be cut or modified on-site to fit complex layouts .
