Types of Fiberglass Cable Tray Supports

Fiberglass cable tray supports include ladder, trough, channel, and covered types, each designed for specific cable protection, ventilation, and load requirements.

Ladder Type Fiberglass Cable Tray

Ladder trays consist of two side rails connected by transverse rungs, forming a ladder-like structure. This open design allows excellent ventilation and heat dissipation, making it ideal for power cables and large-diameter control cables. Ladder trays are commonly used in power distribution, substations, and industrial plants.

They are easy to install, modify, and are available in light, medium, and heavy-duty load classes with varying rung spacing to accommodate different cable weights and sizes.

Trough or Channel Type Fiberglass Cable Tray

Trough or channel trays have a bottom plate with side rails, providing more protection for cables while still allowing some ventilation. They are suitable for control, communication, and instrumentation cables that require shielding from dust, debris, or mechanical damage. These trays are often used in telecom, computer, and sensitive signal cable installations.

Channel trays are compact and ideal for short runs or areas with space constraints.

Covered Fiberglass Cable Tray

Covered trays include a removable or fixed cover to protect cables from rain, UV exposure, dust, and falling objects. They are particularly useful in outdoor telecom sites, industrial plants, and corrosive environments. The cover enhances cable longevity and reduces maintenance needs while maintaining the lightweight and corrosion-resistant benefits of FRP.

Other Considerations

Fiberglass cable trays are lightweight, non-conductive, corrosion-resistant, and flame-retardant, making them suitable for harsh environments such as chemical plants, offshore oil and gas facilities, and coastal installations. They can be customized in resin type, wall thickness, and support spacing to meet specific load and environmental requirements. Accessories like bends, tees, reducers, and mounting hardware allow flexible installation and routing.

Summary

Choosing the right fiberglass cable tray support depends on cable type, load, environmental exposure, ventilation needs, and installation constraints. Ladder trays are best for heavy power cables and long runs, trough or channel trays for sensitive or protected cables, and covered trays for outdoor or corrosive conditions.
