Composite material trough-type cable trays

Trough-type cable trays made from composite materials like FRP provide durable, corrosion-resistant, and electrically non-conductive support for cables in harsh industrial and outdoor environments.

Overview

Composite material trough-type cable trays are typically made from fiberglass-reinforced plastic (FRP) or glass-reinforced polymer (GRP), combining high-strength fibers with a resin matrix to create a lightweight yet robust support system for electrical and data cables. The trough design features a bottom plate with side rails, offering more protection than ladder-type trays while still allowing some ventilation for heat dissipation. This makes them ideal for control cables, communication lines, and instrumentation circuits that require shielding from dust, moisture, and mechanical damage.

Key Advantages

Corrosion Resistance: FRP trays are highly resistant to chemicals, saline environments, and industrial pollutants, unlike steel trays which can rust or corrode. Electrical Insulation: Being non-conductive, FRP trays reduce the risk of electrical hazards and electromagnetic interference, making them suitable for sensitive installations. Lightweight and Strong: FRP offers a high strength-to-weight ratio, supporting heavy cable loads while remaining easy to handle and install.

Fire and U

V Resistance: Many FRP trays meet fire safety standards (UL-94, ASTM E84) and include UV inhibitors for outdoor durability. Low Maintenance: Once installed, these trays require minimal upkeep, with no need for grounding or corrosion-related repairs. ApplicationsTrough-type FRP cable trays are widely used in chemical plants, offshore platforms, water treatment facilities, power plants, and industrial complexes where environmental conditions are harsh.

They are also suitable for outdoor installations due to their UV and weather resistance. Optional covers can be added to protect cables from rain, snow, or falling debris, enhancing safety and longevity.

Installation and Design Considerations

Support and Mounting: FRP trough trays can be mounted on walls, ceilings, or elevated supports. They are compatible with FRP couplers, hangers, and support hardware. Ventilation: While the trough design provides partial ventilation, covers can be used in environments with high dust or moisture.

Customization: Available in various lengths, widths, and load capacities to accommodate different cable bundles and installation requirements.

Conclusion

Composite material trough-type cable trays offer a reliable, long-lasting, and safe solution for cable management in demanding environments. Their combination of corrosion resistance, electrical insulation, lightweight strength, and low maintenance makes them a superior alternative to traditional metal trays, particularly in industrial, chemical, and outdoor applications.
