Bridge-type cable trays and ladder-type cable trays

Fiber optic splice closure knowledge brief Published 22 Nov 2023

Prepared for preliminary research by the RIVO OPTICAL knowledge desk. Confirm cable count, splice capacity, sealing class, tray layout, protection sleeves and installation requirements against current standards and product documentation.

A bridge-type cable tray is not the same as a ladder-type cable tray; ladder trays have rungs like a ladder, while bridge-type trays are typically solid or perforated flat structures.Ladder-Type Cable Trays

Ladder-type cable trays, also called cable ladders, consist of two longitudinal side rails connected by evenly spaced rungs, resembling a ladder . This open design allows excellent ventilation, making them ideal for heavy-duty power cables and long-span installations . Cables can be easily accessed from the top or bottom, and the rungs allow secure fastening with cable ties or cleats. Ladder trays are commonly used in industrial plants, refineries, and power stations where large cables need robust support .

Bridge-Type Cable Trays

Bridge-type cable trays, sometimes referred to as solid or perforated trays, consist of a flat sheet of metal forming the base, often with slots or perforations for ventilation and cable fastening . Unlike ladder trays, they do not have rungs and provide continuous support along the cable length, which is useful for lightweight cables, instrumentation, or telecommunication lines. The enclosed or semi-enclosed design can also reduce electromagnetic interference and protect cables from environmental factors .

Key Differences
  • Structure: Ladder trays have rungs; bridge trays have a flat base.
  • Ventilation: Ladder trays offer maximum airflow; bridge trays provide moderate ventilation through perforations.
  • Applications: Ladder trays are suited for heavy power cables and long spans; bridge trays are better for lighter cables, sensitive instrumentation, or areas requiring EMI protection.
  • Accessibility: Ladder trays allow easier cable entry and exit along the run; bridge trays provide continuous support but less direct access. In summary, while both types are cable support systems, a bridge-type cable tray is not a ladder-type cable tray, and each is chosen based on cable weight, environmental conditions, and installation requirements .
