Composite Cable Tray Models and Specifications

Composite cable trays, typically made from FRP/GRP, offer lightweight, corrosion-resistant, and fire-retardant solutions for industrial and commercial cable management.

Types of Composite Cable Trays

1. Ladder Type Cable Tray

• Constructed with two side rails connected by transverse rungs.
• Open design allows excellent ventilation and heat dissipation.
• Suitable for power cables, large-diameter control cables, and industrial plants.
• Available in light, medium, and heavy-duty load classes with variable rung spacing . 2. Trough or Channel Cable Tray
• Features a bottom plate with side rails, providing moderate protection while allowing some ventilation.
• Ideal for control, communication, and instrumentation cables.
• Can be supplied with optional covers for outdoor or dusty environments . 3. Solid Bottom Cable Tray
• Fully enclosed bottom and continuous side walls.
• Offers maximum protection against dust, liquids, and mechanical damage.
• Commonly used in sensitive or harsh environments . 4. Cushioned or Specialized Designs
• Some manufacturers provide cushioned trays for vibration-sensitive installations.
• Accessories include covers, divider strips, drop-outs, blind ends, adapters, hold-down clips, marine rungs, and strut rungs .

Materials and Resin Types

• Polyester Resin: Standard, UV and weather-resistant.
• Vinylester Resin: Superior corrosion and heat resistance.
• Epoxy Resin: Excellent electrical insulation for power projects.
• Phenolic Resin: Low smoke and toxicity, fire-retardant . All composite trays are non-conductive and non-magnetic, making them suitable for electrical and instrumentation applications.

Specifications and Features

• Load Capacity: Varies by tray type and resin; modular systems allow site-specific load handling.
• Span: Pultruded FRP profiles can achieve long spans without intermediate supports.
• Environmental Resistance: Resistant to corrosion, UV, extreme temperatures, moisture, and chemicals .
• Installation Options: Wall-mounted, roof-mounted, or floor-mounted.
• Modularity: Systems include straight sections, bends, tees, reducers, and connectors for flexible layouts .

Applications

• Industrial Plants: Chemical, power, and manufacturing facilities.
• Commercial Buildings: Offices, hotels, and supermarkets.
• Infrastructure Projects: Transportation, marine, and water treatment facilities.
• Harsh Environments: Corrosive, high-temperature, or fire-sensitive areas .
