Cable tray CT and FT

CT trays are continuously perforated, low-profile trays ideal for light to medium cable loads, while FT (Ladder or Trough) trays are designed for heavier loads and better heat dissipation.

C

T Cable TraysCT (Continuous Trough) cable trays are made from a single piece of material with continuous perforations along the base. They are designed for economical installation, shallow cable depth, and low-profile applications while maintaining good load-bearing capacity. Key features include: Perforated design: Allows maximum airflow around cables and easy securing with cable ties.

Material: Typically steel or aluminum, providing strength and durability. Installation: Pre-made fittings and taper-folded edges allow quick assembly and smooth joining of tray sections. Applications: Suitable for commercial and industrial sites where cable loads are moderate and a low-profile system is preferred.

Width range: 75–600 mm, accommodating various cable bundles.

F

T Cable TraysFT trays generally refer to Ladder or Trough (perforated) trays used for heavier cable loads and long support spans. They are designed to provide mechanical support, strain relief, and heat dissipation for large power or data cable runs. Key characteristics include: Ladder trays: Open rung design allows air circulation, reducing heat buildup and simplifying installation of large cables.

Trough/perforated trays: Provide continuous bottom support with ventilation openings, suitable for medium loads and sensitive instrumentation cables. Material thickness and side rail height: Critical for load capacity and long-term durability. Wider trays are preferred for high-current or solar DC runs to reduce cable stacking and heat concentration.

Applications: Ideal for industrial plants, data centers, and commercial buildings where heavy cable bundles and long spans are common.

Choosing the correct tray type depends on cable load, installation environment, and airflow requirements.
