Covers:There are different types of covers.

1.Tray Covers

Tray covers are available for all classes of tray. They should be installed where falling objects may damage cables or where a vertical tray run is accessible by pedestrian or vehicular traffic.

Outside cable tray runs should be covered with a peaked flanged cover to protect cable from the elements and excess build up of snow and ice.

2.Solid Covers

These covers provide maximum mechanical protection for cables with limited heat build up. Solid covers are available with or without flange.

3.Ventilated Flanged Covers

This design offers excellent mechanical protection while allowing heat produced by cables to dissipate.

4.Peaked Flanged Covers

Peaked covers offer mechanical protection plus prevent accumulation of liquid on the cover. Peaked covers have 15° rise at the peak. 

Covers shall be supplied to protect tray cable where needed. Covers will be solid and contain three pair of turn-bolt locks to secure the covers to the lips of the cable tray, requiring only the use of a slotted screwdriver. 

Covers provide mechanical and environmental protection for cables being carried by cable ladder or cable tray, can be closed or ventilated and should be fitted in accordance with the manufacturer’s instructions. 

When covers are installed on outdoor cable ladder or cable tray, another factor to be considered is the aerodynamic effect which can produce a lift strong enough to separate a cover from an installation. Wind moving across a covered system creates a positive pressure inside the cable ladder or cable tray and a negative pressure above the cover (Bernoulli effect). This pressure difference can result in the cover being lifted off which can result in damage to the installation and possible injury to personnel or to the public.

It is recommended that closed cover types or covers with heavy duty cover clamps are used when an installation requiring covers is likely to be susceptible to strong winds. 

Covers on wide cable tray and/or cable tray installed at elevations high off the ground may require additional heavy duty clamps or thicker cover material.
