Cable Tray Benefits

The 7 major benefits of a cable tray system (also referred to as cable ladder tray, ladder tray, LT3 or LT5 tray, Unistrut tray, 3 series or 5 series tray, burndy ladder tray, perforated tray, square edged tray) are:

1.) Safety features:

  • Doesn’t allow a path for corrosive, explosive or toxic gases to travel (by being open and aerated).
  • Doesn’t pipe explosive gases into the critical area e.g.
    • Maryland Columbia Liquefied Natural Gas facility had explosive gas travel through their conduit system, demolishing the substation, killing the foreman and badly burning an operator. This wouldn’t have occurred with a cable tray system.

2.) Dependability:

  • Over 40 years experience providing outstanding dependability for the control of data handling, instrumentation, communication and power systems
  • The most common industrial wiring system in the world.

3.) Space savings:

  • Can route more cables in substantially less space (and with less costs).

4.) Design cost savings:

  • Time
    • Can easily cope with continuous changes during engineering and drafting design phases.
  • Speed
    • Final drawings can be completed faster and sent out for bid or construction.
  • Flexibility
    • Cable can easily enter and exit cable trays anywhere along its route, allowing highly flexible designs.
    • Can be fabricated onsite, so specifications can be easily changed at any time.
  • Space
    • A cable tray system can hold greater volume than a conduit system.
    • A cable tray system allows for future expansion of services i.e. you can easily run additional services on existing cable tray (e.g. airports, hospitals).

5.) Installation cost savings:

  • Initial installation usually costs 10%-40% less (depending on the complexity and size).
  • Full installation is faster so there is less work space conflict with other construction disciplines (especially true if installations are elevated and if significant amounts of piping are being installed on the project).
  • Labour cost savings are significant (especially where banks of conduit would have been required).
  • Require only small electrician crews to install.
  • Have less individual components to be installed so handling time reduces.
  • Doesn’t require pull boxes, splice boxes or concentric bends. 
  • Cable pulling is less complicated and less time consuming.
  • Cable insulation damage is less common (since jamming doesn’t occur).

6.) Material savings:

  • Excluding cables (which typically cost the same) the cost of the cable tray supports and miscellaneous materials are significant cheaper.
  • Substantial cable tray capacity increases for a nominal additional cost e.g. when width is increased by 150mm, the cable tray cost increase is less than half.

7.) Maintenance savings:

  • Cables are easily installed in existing trays if there is space available (meaning faster wiring additions or modifications with minimum disruption to operations). 
  • Moisture passes through cable trays without pooling (like in a conduit system). Please note, moisture is a major cause of electrical equipment and material failure.
  • Damage to cable trays due to fire is most often limited to the area of the flame contact plus a few metres on either side. Please note, at an Ohio chemical plant, a fire damaged banks of conduits and runs of cable tray. The cable trays were repaired in 2 days. The conduits were repaired in 6 days.
  • Doesn’t have to be pulled into the termination equipment enclosure (a real advantage for projects with significant numbers of large cable terminations in switchgear).
