Does the cable tray include a cover plate

Fiber and communications infrastructure knowledge brief Published 02 Apr 2023

Use this reference to prepare product questions for CJC FIBRE. Check interfaces, capacity, protection and installation requirements against the current product documentation.

Cable trays can include cover plates, but whether a cover is provided depends on the tray type and application requirements. Cable trays are designed to support and organize electrical cables, and many systems offer optional or integral covers to protect the cables. Solid or ventilated covers can be added to ladder, trough, or channel-type trays to provide protection against dust, moisture, and electromagnetic interference, or to meet aesthetic or safety requirements.

Types of Cable Tray CoversDome-shaped, flat, peaked, corrugated, flanged, and perforated covers are commonly used, depending on the application and environmental conditions. Solid covers provide maximum protection and EMI/RFI shielding, while ventilated or perforated covers allow airflow to dissipate heat from current-carrying conductors. Covers can be made from metal, composite, rubber, or plastic, with metal and composite being the most common in industrial applications.

Standards and Specifications

Cable tray systems are defined to include straight sections, bends, tees, elbows, supports, and accessories, which may include covers. For steel trays, covers are typically made from mill or hot-dip galvanized steel, while aluminum and stainless steel trays have covers made from corresponding alloys. The inclusion of a cover is often determined by safety codes, environmental conditions, and the need for EMI/RFI protection.

Practical Considerations

Ladder trays often do not include covers by default to maximize airflow and reduce dust accumulation. Solid bottom trays or trays in sensitive installations may require covers to protect cables from moisture, dust, or mechanical damage. Covers are usually purchased as part of the tray system or as separate accessories, depending on the manufacturer and project specifications.

In summary, while cable trays can include cover plates, the decision to use a cover depends on the tray type, environmental conditions, and protection requirements. Covers are available in various designs and materials to suit specific applications.
