Cable Ladder

Cable Lader is used in the cable tray wiring system installations. It is the predominate cable tray type due to its many desirable features : 

A cable ladder without covers opermits the maximum free flow of air around the cables. This allows the produced in cable's conductors to effectively dissipate.

The rungs of the cable ladders provide convenient anchors for tying down the cables in any non-horizonal cable tray rungs or where the positions of the cable must be maintained in the horizontal cable tray rungs.

Cables may exit or enter the cable ladders through the top or the bottom of the cable tray. Where the cables enter or exit conduit, the conduit to cable tray clamps may be installed upright or inverted to terminate conduits on the top or bottom of the cable tray side rail.

The most common rung spacing for cable ladder is 300mm. But the slight amount of small diameter cable droping between may be aesthetically objectionable for some installations.
